EMQX vs Mosquitto: which MQTT broker fits your production design
Your device fleet or IoT platform needs MQTT in production, and the first decision is which broker to run. Choose Eclipse Mosquitto for a lightweight single broker under EPL-2.0 or BSD-3-Clause, where the workload fits one node and you want a small footprint from low-power single board computers up to full servers. Choose EMQX when you need clustering, a SQL-based rule engine and data integration with more than 50 systems, accepting the Business Source License and, for any cluster of more than one node, a license file. The decision turns on four things: how many nodes you need for availability, how many downstream systems the device data must reach, whether your legal team accepts the EMQX license terms, and how much operating capacity your team has to run clustering and integrations.
Start with cluster needs. Mosquitto's bridge option, documented in the mosquitto.conf manual, connects multiple brokers together, and its certificate and pre-shared-key TLS settings apply to bridge connections. That works for distributing load across a few sites, but you should test failover behavior against your own topology. Mosquitto's high availability, integrations, REST APIs and persistent queuing sit in Cedalo's commercial Pro Edition, so confirm with Cedalo which of those features your design needs before assuming they are included in the open-source build. EMQX offers masterless clustering in its open source line, and the license file requirement applies from version 5.9.0 onward. Confirm the current license terms in the EMQX LICENSE file for your exact release, because each release converts to Apache 2.0 four years after publication.
Which scenarios favor EMQX and which favor Mosquitto
This table maps common MQTT deployment scenarios to the broker that fits each one better, and names the condition that tips the choice. Read each row against your own topology, data destinations and who will use the service, because the license terms for production clustering and third-party hosting often decide the outcome.
| Scenario | Better fit | Condition that makes it so |
|---|---|---|
| Single-site broker on a gateway device | Mosquitto | Mosquitto is described as lightweight for devices from low-power single board computers upward, and its EPL-2.0 or BSD-3-Clause license places no cluster condition on one broker. EMQX also runs on one node in production under its single-node grant, so confirm footprint on your hardware before choosing. |
| Multi-node cluster for a regional fleet | EMQX | EMQX offers masterless clustering, but from 5.9.0 a cluster of more than one node requires loading a license file. Mosquitto's open-source edition does not provide high availability, so a clustered design there points to the commercial Cedalo Pro Edition, which you should price with Cedalo. |
| Pushing device data into Kafka or PostgreSQL | EMQX | EMQX's SQL-based rule engine and data integrations cover Kafka, PostgreSQL and more than 50 systems in total. Mosquitto's bridges connect brokers to each other, so an external consumer or pipeline must be built and operated separately. |
| Hosted service offered to third parties | Neither open edition without legal review | The EMQX license does not permit offering the software to third parties on a hosted or embedded basis, so a hosted offer needs a commercial agreement with EMQX. Mosquitto's permissive EPL-2.0 or BSD-3-Clause terms should be reviewed by counsel against your own service model. |
| Nonprofit or educational deployment | EMQX | The EMQX license allows production use without restriction by educational and non-profit users for non-commercial purposes, which covers clustering for that use case. Confirm that your use meets the non-commercial condition before relying on it. |
| Small deployment needing only core MQTT | Mosquitto | If you need MQTT 3.1.1 or 5.0 with TLS and client certificates and no rule engine, Mosquitto's smaller operational surface may suit you. Check that the bridge and admin tooling cover your operations model. |
| Protocol coverage beyond MQTT | EMQX | EMQX supports MQTT over QUIC and gateways for MQTT-SN, CoAP and LwM2M. Mosquitto's documented scope is MQTT, so confirm any other protocol with the Mosquitto project before assuming support. |
How each broker is built and what that means for operations
Mosquitto and EMQX make different bets about where complexity lives. One keeps the broker small and pushes scale and integration into bridges and your own tooling, the other builds clustering, gateways and data integration into the platform. The cards below show what each design means for upgrades, monitoring and failure handling, and what to confirm before you commit.
Mosquitto as a lightweight C broker
Mosquitto is a single broker process with a small footprint, documented as suitable for devices from low-power single board computers to full servers. Its operating model is simple: one binary, one configuration file, and a set of command-line tools for publishing, subscribing and administration. This suits sites where the broker is one component among many and the team wants few moving parts. Confirm the supported platforms and the upgrade path for each node in the version you plan to run, since every broker in your fleet is upgraded separately.
Bridges connect Mosquitto brokers
Mosquitto does not cluster in the way EMQX does. Multiple brokers are connected with bridges, which forward selected topics from one broker to another. Bridge connections can use certificate-based TLS or pre-shared-key TLS, so each link is authenticated at the transport layer. Operationally, you own the topology: you decide which topics cross which bridge, and a loop or misconfigured topic filter must be caught in your own review. Confirm the bridge configuration keys and the reconnect behavior in the manual before designing the topology.
EMQX as a masterless cluster
EMQX runs as a clustered platform in which nodes share the session and routing state without a single master node. For operations, this means a node can be added or replaced without designating a leader to fail over. Failure handling still needs testing: you should confirm how client sessions are handed over when a node drops, how the cluster behaves during a network partition, and how many nodes your license covers. The license note applies here, because from EMQX 5.9.0 a cluster of more than one node requires a license file.
Gateways for constrained protocols
EMQX includes gateways for MQTT-SN, CoAP and LwM2M, so constrained devices that do not speak MQTT directly can connect through the same platform. Mosquitto does not provide these gateways, so a site with such devices typically adds a translation component that it must patch and monitor on its own. Running gateways inside the broker reduces the number of services, but it also means one upgrade cycle covers more protocol surface. Confirm which gateway features your edition and license include before you plan device onboarding.
SQL rule engine and integrations
EMQX evaluates SQL-based rules on incoming messages and forwards results to downstream systems, with data integration to more than 50 systems. Rules move logic out of application code and into the broker configuration, which changes what you must monitor: rule errors, failed connector calls and backpressure now appear as broker metrics rather than as application logs. With Mosquitto, the equivalent work usually sits in a subscriber service that your team writes, tests and runs. Confirm how rule failures are retried and surfaced in the metrics your team already collects.
Upgrades, monitoring and version pinning
Both projects publish releases on GitHub, and the release cadence determines how often you schedule maintenance. Mosquitto 2.1.2 was tagged on February 9, 2026, and EMQX 6.3.2 was published on October 16, 2026. Before choosing a version, confirm the upgrade notes between your current release and the target, the supported configuration changes, and the metrics each broker exposes for alerting. A single broker is easier to roll back. A cluster needs a rolling upgrade plan that keeps enough nodes online for client sessions to survive each step.
Why the license file decides when a cluster is allowed
For EMQX, the cluster question is a licensing question before it is an architecture question. Starting with version 5.9.0, EMQX unified its former Open Source and Enterprise editions into a single offering under the Business Source License 1.1. Under that license, a single production node is permitted, provided the deployment is not offered to third parties on a hosted or embedded basis. From 5.9.0 onward, running a cluster of more than one node requires loading a license file. Before you design a multi-node EMQX deployment, confirm with the EMQX vendor which license tier and file your node count, regions and redundancy model require, and have your legal counsel read the license text against your intended use, including any customer-facing or embedded use.
The license also has a time dimension. Each EMQX release under the Business Source License converts to Apache 2.0 four years after it is published, so the terms that apply to a given version are fixed at its publication date. Plan your upgrade path with that in mind: a version you deploy today will not automatically become open terms for years, and a future upgrade may come with different commercial conditions. Ask the vendor for the current license terms in writing and record which EMQX release and license file each environment runs.
Eclipse Mosquitto takes the opposite approach at the license level. Mosquitto is dual licensed under the Eclipse Public License 2.0 or the Eclipse Distribution License 1.0 (EPL-2.0 OR BSD-3-Clause), so a broker in a multi-node design carries no license file requirement from the project itself. The trade-off is in the feature set. High availability, integrations, REST APIs, persistent queuing, cloud deployment and professional support are offered in Cedalo's commercial Pro Edition, not in open-source Mosquitto. If your cluster depends on high availability or durable queuing, price the Pro Edition alongside EMQX's license file in your comparison, and ask Cedalo and your legal counsel to confirm the Pro Edition terms before you rely on them.
Protocol, clustering, rule engine and authentication compared
This table compares what each broker supports at the protocol, clustering, rule engine and authentication layers. Read it as a checklist: where a row says EMQX only, the feature is absent from Mosquitto's supplied capabilities, and where a row asks you to confirm, the answer depends on your Mosquitto build or Pro Edition. The main takeaway is that EMQX covers more of the stack out of the box, while Mosquitto stays smaller and simpler for single-broker setups.
| Capability | EMQX | Eclipse Mosquitto |
|---|---|---|
| MQTT versions | MQTT 5.0, 3.1.1 and 3.1 | MQTT 5.0, 3.1.1 and 3.1 |
| MQTT over QUIC | Supported | Confirm with the Mosquitto docs for your build before relying on it |
| Gateway protocols | MQTT-SN, CoAP and LwM2M through gateways | Not listed in supplied facts; confirm with the vendor |
| Clustering | Masterless clustering; clusters of more than one node need a license file from 5.9.0 | Multi-broker connection via bridges; high availability is listed in the Pro Edition, so confirm open-source options |
| Rule engine and integrations | SQL-based rule engine and data integration with more than 50 systems, including Kafka, PostgreSQL and Redis | Not part of the core broker; integrations are a Pro Edition feature |
| Bridges and connectivity | Data integration through the rule engine | Bridges connect multiple Mosquitto brokers, with certificate and pre-shared-key TLS options |
| Authentication methods | Username and password, JWT, PSK and X.509 certificates over TLS/SSL and secure WebSocket | Confirm the supported methods and plugin model for your version in the mosquitto.conf manual |
| Client and admin tools | Confirm the tooling set in the EMQX documentation | mosquitto_pub, mosquitto_sub, mosquitto_rr, mosquitto_ctrl and mosquitto_passwd, plus C and C++ client libraries |
| Public test server | Confirm availability with EMQX before testing | test.mosquitto.org supports plain MQTT, TLS, client certificates and WebSockets |
| Latest release | EMQX 6.3.2, published October 16, 2026 | Mosquitto 2.1.2, tagged February 9, 2026 |
What each license allows and what each vendor sells
EMQX moved from Apache 2.0 to the Business Source License 1.1 starting with version 5.9.0, when its Open Source and Enterprise editions became a single offering. The license grants production use of a single node, so a standalone broker in your own environment does not need a commercial agreement under the terms of the license file. The grant stops at the boundaries the license draws, and those boundaries determine what you can build.
- Single-node production grant: The license permits production use of a single node, provided the node is not offered to third parties on a hosted or embedded basis.
- Hosted and embedded restriction: Offering EMQX to customers as a managed service or bundling it inside a product you sell is outside the grant. Confirm this with the license text before you plan a service model.
- Educational and non-profit use: Educational and non-profit users may use EMQX in production without restriction for non-commercial purposes.
- Cluster license file: From 5.9.0, a cluster of more than one node requires loading a license file, so multi-node production needs a license arrangement with EMQX.
- Four-year conversion: Each release converts to Apache 2.0 four years after publication, so older releases become Apache-licensed over time.
Confirm with EMQX and your legal team whether your single-node deployment is internal use, whether your architecture ever runs EMQX for a third party, and which license file terms apply to your planned cluster size.
Eclipse Mosquitto is dual licensed under the Eclipse Public License 2.0 or the Eclipse Distribution License 1.0, which is SPDX EPL-2.0 OR BSD-3-Clause. You may choose whichever license fits your use. The open-source broker has no node count restriction in its license, so the licensing question for Mosquitto is less about production scale and more about what you need the broker to do beyond core MQTT. The commercial path sits with Cedalo, which develops Mosquitto and sells a Pro Edition.
- Dual licensing: The project offers EPL-2.0 or BSD-3-Clause, and your legal team can select the one that matches your distribution model.
- Core open-source scope: The open-source edition covers core MQTT features, on-premises deployment and community forum support, according to mosquitto.org.
- Pro Edition high availability: Cedalo's commercially licensed Pro Edition adds high availability, which the open-source edition does not list.
- Pro Edition integrations and REST APIs: The Pro Edition adds integrations, REST APIs and persistent queuing.
- Pro Edition support and cloud: The Pro Edition adds cloud deployment and professional support.
Confirm the current Pro Edition terms, pricing model and support tiers directly with Cedalo, and check whether the open-source bridge configuration in the mosquitto.conf manual meets your redundancy needs without the Pro Edition.
What drives the running cost of each broker
This table sets out who is paid for what when running EMQX or Mosquitto, which costs are one-time and which recur, and what drives each one up or down. Read it as a checklist for a quote request: the licensing rows depend on whether you need a multi-node cluster or high availability, and the effort rows depend on your team's existing skills.
| Cost component | EMQX | Eclipse Mosquitto | What to request or confirm |
|---|---|---|---|
| Infrastructure footprint on devices and servers | Runs as a broker server with more resource needs than a lightweight daemon; sizing depends on connection count and rule load | Designed to run from low-power single board computers to full servers, so the smallest footprint of the two | Ask the vendor or DeployOpen for sizing against your connection count, message rate and retention, tested on your hardware |
| Cluster sizing and node count | Masterless clustering; a cluster of more than one node needs a license file from 5.9.0, so node count affects license scope | Single broker by default; multiple brokers are joined with bridges, which must be designed and monitored by your team | Ask for node count, failover design and expected growth, and whether the quote covers each node or the cluster |
| EMQX license for clusters | Recurring or term-based only if the vendor's license terms require it; the BSL 1.1 single-node production grant does not cover clusters | No license fee for the open-source broker; the EPL-2.0 or BSD-3-Clause terms apply | Request the EMQX license price in writing from the vendor, with the term, node scope and renewal conditions stated |
| Cedalo Pro licensing for high availability | High availability is built into the clustered platform under the same license model | Cedalo's commercially licensed Pro Edition adds high availability, integrations, REST APIs and persistent queuing; this is a separate recurring cost | Ask Cedalo which features you need, the license basis, support terms and renewal, and whether Pro is required for your HA design |
| Staff skills and training | Team learns the EMQX configuration model, rule engine and cluster operations; one-time ramp-up, then ongoing operating skill | Simple configuration and a small surface area; bridge and TLS design still need experienced staff for multi-site setups | Map existing skills to each platform and estimate training time with your own team lead, since no supplied figure applies |
| Upgrade and testing effort | Recurring with each release; test clustering, rule changes and license compliance before upgrades | Recurring with each release; smaller change surface, but bridge and plugin behavior still needs regression tests | Ask for the upgrade path, release cadence commitments and whether DeployOpen or the vendor provides regression test suites |
| Support options | Vendor support tiers sold alongside the license; response terms depend on the contract | Community forum support for open-source use; professional support comes with the Cedalo Pro Edition | Compare community and paid support options in writing, including response times and escalation paths |
| Integration build work | Rule engine and data integration with more than 50 systems, including Kafka, PostgreSQL and Redis, reduce custom code but still need configuration and testing | Core MQTT features are built in; data integration to databases or streams usually needs custom clients or Pro integrations | Inventory each downstream system and scope the build as a fixed-scope piece of work with written deliverables |
Moving a Mosquitto deployment to EMQX, or the reverse
This sequence gives a team a tested path between a Mosquitto deployment and an EMQX cluster, with devices moved in controlled batches, so the cutover happens only after both brokers have carried the same traffic. The output is a migrated fleet, a documented authentication and rule mapping, and a rollback path that stays open until the old broker is retired.
Inventory topics, QoS levels and retained messages
Start by exporting the topic tree, the QoS level each publisher and subscriber uses, and the set of retained messages the broker holds. Your platform or IoT engineers should record which topics carry commands, which carry telemetry, and which depend on retained values for new subscribers to start correctly. Also list every bridge defined in mosquitto.conf, since bridges are the mechanism Mosquitto uses to connect brokers and they will need an explicit replacement. You know this step is done when every topic has an owner, a QoS value and a retention decision, and the bridge list is signed off by the team that depends on it.
Map Mosquitto authentication to EMQX methods
Compare the password file, client certificate and any access control list configured on the current broker with the authentication options EMQX documents, which include username and password, JWT, PSK and X.509 certificates. Security engineers should decide which identity source each device class will use in EMQX and confirm that the chosen method works over the TLS or secure WebSocket connections your devices use today. Confirm in the EMQX documentation how authorization rules are expressed, because access control does not carry over as a file copy. The step is complete when each device class has a named authentication method and a test device has authenticated successfully against a staging EMQX node.
Rebuild rules and integrations in the rule engine
Any processing that ran outside the broker, such as a subscriber that wrote telemetry to a database or forwarded messages to another system, needs a decision: keep it as an external consumer, or rebuild it as an EMQX rule. EMQX provides a SQL-based rule engine and data integrations with a documented list of systems, so an integration engineer should check that each target system appears in that list or can be reached through an existing connector. Write each rule against sample payloads from the inventory and compare the output with what the old subscriber produced. The step closes when every rule has a matching test case and the outputs agree on the sample set.
Run both brokers in parallel with bridging
Stand up the EMQX cluster beside the existing Mosquitto broker and connect them with a bridge so messages published on one reach subscribers on the other. The platform team should confirm the EMQX license position before this stage, since a cluster of more than one node needs a license file from EMQX 5.9.0 onward, and a single node carries different terms. Monitor both brokers for message loss, duplicate delivery and topic mismatches during a period you set based on your own risk tolerance. The step is done when a defined set of test topics has shown consistent delivery in both directions and no unexplained loops or duplicates appear in the logs.
Migrate devices in batches
Move devices to EMQX in small, labeled groups, starting with a device class that is easy to recover and has a clear owner. For each group, update the broker address and credentials in the device configuration, then verify that the device reconnects, publishes at its expected QoS and receives commands. Keep a record of which devices have moved so a failed batch can be returned to Mosquitto without guessing. Devices with limited update channels or long firmware cycles should be identified early, because they will set the pace of the whole migration. The step is complete when every batch has passed its acceptance checks and the device inventory shows one broker of record for each device.
Cut over TLS certificates per device class
Plan certificate changes as their own step, because a device that trusts only the old certificate authority will refuse an EMQX endpoint presenting a different chain. Security engineers should confirm which certificate authority, server certificate and client certificate arrangement each device class expects, and whether pre-shared keys or X.509 client certificates are used in the EMQX configuration. Test the new chain on a device from each class before rolling it out, and keep the old trust anchor in place until the last device has moved. The step is done when each device class connects to EMQX over its production TLS configuration and the old trust anchor is scheduled for removal in a dated change record.
Confirm what does not transfer before cutover
Some behavior will not carry over automatically, and the team should check each item explicitly. Retained messages held by Mosquitto are not copied by a bridge in the sense that matters for new subscribers, so confirm how the EMQX side will receive its initial state. Client session state, subscription lists and any custom plugins or dynamic security settings must be recreated or replaced. Confirm the behavior of your Mosquitto bridge topic mappings against the EMQX rule and bridge configuration rather than assuming equivalence. Record each gap, its owner and its resolution in the cutover checklist before any production device is switched.
Test failure and rollback before retiring Mosquitto
Before the final cutover, rehearse the failure cases the operations team is most likely to face: an EMQX node leaving a cluster, a credential rejected for one device class, a rule that fails on malformed payloads, and a full return to Mosquitto. Measure whether devices reconnect within the window your service requirements set, and whether messages published during the failure are recovered or lost. The reverse path should be tested with the same care, because a migration from EMQX back to Mosquitto has the same gaps in reverse. Retire the old broker only after the rehearsals pass and the rollback procedure has been written and tested by someone other than its author.
Where MQTT broker projects usually run long
Most MQTT projects lose time on device identity long before they lose time on the broker. Whichever broker you choose, every device needs a credential the broker will accept, and that credential has to be issued, rotated and revoked across the fleet. With Mosquitto, the usual path is X.509 client certificates or username and password files managed with mosquitto_passwd, plus TLS settings in mosquitto.conf. With EMQX, you also configure authentication chains, and the options include username and password, JWT, PSK and X.509 certificates. The work that runs long is not the broker configuration itself. It is the provisioning pipeline and the firmware that must trust a new certificate authority or rotate a key. Fleets of devices that cannot update certificates quickly, such as field hardware on constrained networks, are where schedules slip most. Before committing, confirm with your device vendor how certificate replacement works over the air and how long a rollback path takes.
Access control design is the second common source of delay. Mosquitto's access control list is file-based and works well for a bounded set of topics and clients, but large fleets with per-device topic hierarchies tend to grow the file quickly and make changes risky. EMQX moves authorization into its own configuration layer, where rules can be sourced from databases or external services, which suits fleets whose topic permissions change often. That flexibility adds design work: someone must define topic namespaces, decide which identities may publish or subscribe to which trees, and test the rules under denial conditions. Plan for a review cycle with the team that owns device identity, and budget for testing of negative cases, because a permissive rule rarely fails in a way anyone notices early.
Cluster sizing, load testing and integration pipelines add the rest of the effort, and each needs a different skill set. Mosquitto's bridges connect brokers, and the mosquitto.conf manual documents certificate and pre-shared-key options for them, which is straightforward for small topologies but needs careful planning if you need high availability, since Mosquitto's own high availability features sit in Cedalo's commercial Pro Edition. EMQX clusters of more than one node need a license file from 5.9.0 onward, so ask for that requirement in writing before sizing hardware. Load tests should reproduce your real connection churn, retained message volume and QoS mix, and they need an engineer who can read broker metrics and tune the operating system. Integration into PostgreSQL, MySQL, MongoDB, Redis or Kafka is another area where teams underestimate the work. Confirm which connector versions you will run and who owns schema changes on the receiving side. Skills to plan for include TLS and PKI administration, MQTT protocol knowledge, Linux operations and, for EMQX, familiarity with its rule engine and clustering model.
Questions teams ask before choosing or hiring help
What does an EMQX cluster cost in license terms, and who quotes it?
EMQX sets the license price, and EMQX or its sales channel issues the quote, so ask them directly. From EMQX 5.9.0, a cluster of more than one node requires a license file, which makes the cluster license the main recurring licensing line in this comparison. Ask the quote to state the node count it covers, the term, what support is included, how added nodes are priced and what changes at renewal. DeployOpen does not publish or estimate license prices. Implementation effort is a separate line: planning, deployment, device migration and handover are largely one-time costs, quoted from a written scope and agreed before work starts. Confirm the license terms that apply to the exact version you plan to deploy.
Can a small team run Mosquitto alone in production?
Yes, for a single broker, a small team can run Mosquitto without a commercial license, since it is dual licensed under EPL-2.0 or BSD-3-Clause and runs on hardware ranging from low-power single board computers to full servers. The recurring work sits around the broker: TLS and client certificate management, password files, access control lists, monitoring, configuration backups and upgrades. Bridges connect multiple Mosquitto brokers, as the mosquitto.conf manual describes, but high availability and persistent queuing are listed as Pro Edition features. A team that needs failover or durable queuing during outages should confirm what the community build covers before committing to it.
How long does an MQTT broker migration take in practice?
No fixed duration applies, because the length depends on the device fleet and the systems that consume its data. The main drivers are the number of devices, whether they can be moved in waves, whether firmware must be reflashed or only reconfigured, and how topics and access rules map from the old broker to the new one. Authentication also changes the work: EMQX offers username and password, JWT, PSK and X.509 certificates, while Mosquitto uses password files managed with mosquitto_passwd. Downstream consumers and the period when both brokers run in parallel add time. Ask for a written plan with a pilot wave and a rollback step, and a timeline agreed in the written scope before work starts.
What does a broker migration need from device and network teams?
Device teams own the client side: configuration or firmware changes that set the broker address, TLS settings, client certificates or pre-shared keys, client IDs and reconnection behavior. Network teams own firewall rules for MQTT over TLS, WebSocket paths if browsers connect, DNS, load balancer or NAT behavior and the certificate chain. Both teams need a test plan that covers a sample of each device model, approved change windows and a rollback path. Confirm early whether devices accept remote configuration updates, since that decides whether migration happens over the air or during site visits. Agree in advance who signs off each wave.
Is a single EMQX node free for production use?
Under the Business Source License 1.1 in the EMQX LICENSE file, production use of a single node is permitted, provided you do not offer EMQX to third parties on a hosted or embedded basis. Educational and non-profit users may use it in production without restriction for non-commercial purposes. Two limits matter. A cluster of more than one node requires a license file from 5.9.0, and each release converts to Apache 2.0 four years after it is published. Read the EMQX LICENSE with counsel, especially if you embed the broker in a product sold to customers. A single node also provides no node-level redundancy.
Which Mosquitto Pro features do we need before buying?
Start from your requirements, then confirm each one with Cedalo, which drives Mosquitto development and sells the Pro Edition. According to mosquitto.org, Pro adds high availability, integrations, REST APIs, persistent queuing, cloud deployment and professional support, while the open-source edition covers core MQTT features, on-premises deployment and community forum support. Test each item against your needs: failover behavior, the integrations you require, whether you need an HTTP management interface, message durability during outages and whether cloud deployment is mandatory. Request the feature list and license terms in writing, and confirm version compatibility with the Mosquitto release you intend to run.
Can DeployOpen carry out this broker migration for us?
DeployOpen plans, implements, integrates, hardens, backs up, upgrades, documents and supports self-hosted open-source platforms inside your own infrastructure, including cloud accounts, data centers and air-gapped networks. Most engagements are fixed-scope, with scope, deliverables and timelines agreed in writing before work starts. Work can cover broker deployment, TLS and access setup, device and bridge integration, testing and handover. License selection and purchasing stay with your organization and the vendor. Ask for a written scope that names the platform, the broker topology, the device count and the handover items. Ongoing support, upgrades and continuous testing are available as retainers. A quote follows from the written scope, and DeployOpen does not publish a price list.
How DeployOpen helps choose and implement an MQTT broker
DeployOpen starts by mapping your device counts, QoS needs, protocol gateways and license position against EMQX and Mosquitto, then builds the chosen broker inside your own infrastructure. Every step, from the first scope call to the final runbook, is written down so your team can run what was delivered.

How we build
- We install the chosen broker in your cloud accounts, data centers or air-gapped network.
- We configure TLS, client certificates and authentication methods against your written security requirements.
- We connect the broker to downstream systems and test message flow under the agreed load scenarios.
How we hand over
- We document architecture, configuration, certificate handling and backup procedures for your operations team.
- We deliver runbooks for routine tasks, upgrades and incident response tied to your environment.
- We walk your engineers through the deployment so they can operate and extend the broker without us.
How we support
