n8n vs Kestra: when each platform is the right choice
Choose n8n when the core job is connecting business applications and APIs through workflows that a mix of operations staff and developers will build and maintain, especially when the team wants a visual canvas with a large catalog of ready-made integrations. Choose Kestra when the core job is running scheduled and event-driven data or infrastructure pipelines defined as code, with version control and a team comfortable writing declarative YAML. The two overlap in scheduling and webhooks, so the decision rests on the workload rather than on feature checklists.
Start with license terms, because they decide whether the platform can be used at all in your model. n8n is licensed under the Sustainable Use License, which permits use or modification only for your own internal business purposes or for non-commercial or personal use, and files with .ee in their name need an n8n Enterprise License. Kestra's open-source edition is Apache-2.0. If you plan to offer the workflows to customers, embed them in a product, or resell them, have counsel read the n8n terms against that plan before you pilot anything. Confirm the same for Kestra's Enterprise Edition, which is a separate paid product.
Then decide who builds the workflows, because it sets the governance you need before go-live. In n8n, business users and developers often share the canvas, so the controls that matter are SSO, projects, environments and Git version control, which the pricing page places in the Business and Enterprise plans. In Kestra, flows are reviewed as YAML in Git, but the open-source edition has basic authentication, manual secret handling and no audit logging. Kestra Enterprise adds SSO, SCIM, RBAC, audit logs and external secrets managers. Write down which of these controls your auditors or security team require, then price that edition in your quote.
Which platform fits which scenario
This table maps common team scenarios to the platform that fits them better, with the supplied fact behind each choice. Read each row as a starting point: the deciding factor is often licensing, the build model or which governance features your organization must have in the free edition versus a paid tier.
| Scenario | Better fit | Why |
|---|---|---|
| Business app automation by non-engineers | n8n | The visual canvas and more than 1,500 advertised integrations let business users build SaaS-to-SaaS flows without writing YAML. Confirm that the Sustainable Use License allows your intended internal use. |
| Data pipeline orchestration by platform engineers | Kestra | Declarative YAML flows with Git version control, scheduled and event-driven triggers, and hundreds of built-in plugins for databases and cloud storage suit teams who manage pipelines as code. |
| Internal tools that call SaaS APIs | n8n | Visual HTTP and app nodes plus custom JavaScript or Python code let a small team wire up internal APIs quickly. Kestra also calls APIs, but its model favors scripted, reviewed pipelines over canvas-built tools. |
| Infrastructure runbooks and scheduled jobs in Git | Kestra | Flows stored as YAML, edited in a YAML editor that stays in sync with the no-code editor, and tracked through Git integration fit change-controlled operational work. |
| Regulated environment requiring SSO, RBAC and audit logs | Confirm requirements first | Kestra's open-source edition has basic authentication and no audit logging, while SSO, SCIM, RBAC and audit logs sit in the Enterprise Edition. n8n SSO and Git environments are in its Business and Enterprise plans. Confirm which controls your assessor expects before choosing a paid tier. |
| Commercial use of the platform for a product or client service | Confirm requirements first | The Sustainable Use License limits use to internal business, non-commercial or personal purposes, and Kestra's open-source edition is Apache-2.0. Have counsel confirm whether your planned use fits either license. |
| Need for an open-source license with no use restrictions | Kestra | Kestra's open-source edition is Apache-2.0 licensed, whereas n8n is licensed under the Sustainable Use License, which is not an OSI open-source license. |
| Multi-main high availability for the workflow engine | Confirm requirements first | n8n multi-main setup is restricted to Enterprise self-hosted deployments. Kestra's high availability architecture is listed under its Enterprise Edition. Confirm the availability model and paid tier each platform requires for your uptime target. |
How n8n and Kestra are built and what that means for operations
n8n and Kestra both run self-hosted, but they scale and recover in different ways. The cards below cover the deployment shapes, the secrets and encryption requirements, and the Enterprise-only features that decide how much operating work each platform creates for your team.
Regular mode versus queue mode
In regular mode, one n8n process runs triggers, webhooks and executions together, which is simple to operate but ties every workload to a single instance. Queue mode splits the work: the main instance handles timers and webhooks and passes execution IDs to Redis, while worker processes run executions and write results to the database. Running queue mode on SQLite is not recommended, so plan for PostgreSQL before you split the process. Ask your team how many executions must run in parallel before you commit to this shape.
Shared encryption key across workers
Credentials are stored encrypted in the database, and every worker and webhook processor must receive the main instance's encryption key so it can read them. This is an operational dependency: key rotation, secret distribution and container configuration must reach every node at once. Mismatched keys cause workers to fail on credential-bound workflows rather than at deploy time. Confirm in your environment how the key is injected, stored and rotated before you scale out.
Multi-main high availability is Enterprise only
Running several main instances for high availability is restricted to Enterprise self-hosted deployments. It is not available in the Community edition or on n8n Cloud. If your requirement is that the trigger and webhook layer survives the loss of one main instance, that requirement moves the decision to a paid Enterprise License, and you should price it before committing to the architecture. Queue mode with workers is a scaling decision and does not by itself provide multi-main resilience.
Kestra single-server default deployment
Kestra's open-source edition is fully functional for production, but its default deployment runs on a single server, with basic authentication and manual secret and access management. Operations on this shape are straightforward, yet the server is a single point of failure and recovery depends on your own backup and restore process. Decide early whether a single node meets your recovery objective, since the open-source edition does not provide the high availability design described below.
Kestra high availability needs Enterprise
Kestra's high availability architecture is part of the Enterprise Edition. It adds Kafka with Elasticsearch, Redis, AMQP or GCP Pub/Sub queue backends, worker groups, and task runners for Kubernetes and cloud batch services. Each backend is a system your team must run, secure, monitor and upgrade alongside Kestra itself. Ask the vendor which queue backend and worker isolation model apply to your environment and what support covers them.
Operations work each platform creates
n8n's operating load centers on the database, Redis, the encryption key and worker scaling, with optional Enterprise features such as log streaming and external secrets. Kestra's load centers on the server or cluster, queue backends in the Enterprise design, and the secret and access processes you build yourself on the open-source edition. Estimate the staff time for upgrades, since n8n and Kestra both publish breaking-change or major-version guidance. Confirm the upgrade path and who will perform it.
Capability comparison: n8n against Kestra
This table sets n8n's self-hosted features against Kestra's open-source and Enterprise Edition features, row by row. Read the license and governance rows first, because several controls that matter to regulated teams sit in each vendor's paid edition, and confirm any cell marked as a point to confirm before you score the two platforms.
| Capability | n8n | Kestra |
|---|---|---|
| License | Sustainable Use License, which permits internal business, non-commercial or personal use only; files with .ee in the name need an n8n Enterprise License | Apache License 2.0 for the open-source edition; Enterprise Edition is a separate paid product |
| Development model | Visual canvas with custom JavaScript or Python code inside workflows | Declarative YAML flows, editable in a YAML editor, a no-code editor and an AI Copilot that stay in sync |
| Triggers | Workflow triggers and webhooks handled by the main instance in queue mode | Scheduled and event-driven triggers listed in the project README |
| Integrations | More than 1,500 integrations advertised, with all integrations included on every plan | Hundreds of built-in plugins for databases, cloud storage and APIs |
| Scripting | Custom JavaScript or Python inside workflow steps | Scripts in any language run as tasks |
| Git version control | Environments with Git are included only in the Business and Enterprise plans | Git version control integration listed in the project README; confirm the edition it applies to |
| MCP and AI features | Point to confirm: current AI and MCP capabilities in your n8n edition | Built-in MCP server that exposes flows to AI agents, plus AI agent and RAG task types |
| SSO and RBAC | SAML SSO and LDAP included in Business and Enterprise plans; confirm role model needed for your teams | Open-source edition has basic authentication only; SSO, SCIM and RBAC are Enterprise Edition features |
| Audit logs | Log streaming is included only in Business and Enterprise plans; confirm audit log scope | No audit logging in the open-source edition; audit logs are an Enterprise Edition feature |
| Secrets management | Credentials are encrypted with a key that must be shared with all worker and webhook processors in queue mode | Manual secret management in open source; external secrets managers such as HashiCorp Vault and Azure Key Vault in Enterprise Edition |
| High availability and scaling | Queue mode with Redis and workers; multi-main high availability restricted to Enterprise self-hosted | Single-server default deployment in open source; high availability architecture with queue backends and worker groups in Enterprise Edition |
What the license and paid editions allow for each platform
n8n's Sustainable Use License is a source-available license, not an OSI-approved open-source license, and it sets the boundaries for what your team may do with the code. Under the n8n LICENSE.md, you may use and modify n8n for your own internal business purposes or for non-commercial or personal use. Distribution is allowed only free of charge and only for non-commercial purposes. Files with .ee in their name or directory fall outside that grant and need a valid n8n Enterprise License.
- Internal business use: Running workflows for your own staff and systems sits inside the grant, which covers most self-hosted deployments within a single organization.
- Resale and embedding: Reselling n8n, offering it as a managed service to customers or distributing it commercially falls outside the grant, so confirm the boundary before building a product on it.
- Community edition: The free self-hosted Community edition includes unlimited users, workflows and integrations, but it does not include SSO, Git environments or log streaming.
- Business and Enterprise: SSO and LDAP, environments with Git and log streaming are included only in Business and Enterprise, and SAML setup is documented for both. Business is listed as self-hosted only at 667 euros per month billed annually, while Enterprise uses custom pricing. Multi-main high availability is limited to Enterprise self-hosted.
- Enterprise files: Any code in a
.eepath requires an Enterprise License key, so check which parts of your intended feature set depend on it.
Before you standardize, ask counsel to review LICENSE.md against your intended use, and confirm with n8n exactly which features a given plan or key covers.
Kestra's open-source edition is licensed under the Apache License 2.0, a permissive open-source license, and Kestra publishes its feature split in an edition comparison. Kestra describes the open-source edition as fully functional for production. Its identity, secrets and governance controls are limited, and the paid Enterprise Edition adds the controls that many regulated teams need for shared operation.
- Authentication: The open-source edition offers basic authentication only, so a shared instance needs additional controls around access and the network perimeter.
- Secrets and access: Secret and access management is manual in the open-source edition. Enterprise adds external secrets managers such as HashiCorp Vault and Azure Key Vault.
- Audit logging: The open-source edition has no audit logging. Enterprise adds audit logs, which matter when you need to show who changed or ran a flow.
- Enterprise identity and tenancy: SSO, SCIM and RBAC, service accounts and API tokens, multi-tenancy and worker isolation are Enterprise features.
- Scale and high availability: The default open-source deployment is single-server. Enterprise adds a high availability architecture with Kafka plus Elasticsearch, Redis, AMQP or GCP Pub/Sub queue backends, worker groups and task runners for Kubernetes and cloud batch services.
Ask Kestra for the current Enterprise feature list and a written quote for your scope, and have counsel review the Apache-2.0 terms and any Enterprise agreement against your intended use.
What drives the running cost of n8n and Kestra
The running cost of n8n and Kestra depends less on the license fee than on who operates the stack and which components it needs. For n8n, the free Community edition has no subscription, so the recurring cost is the infrastructure, the database and the engineer time to patch and upgrade it. Per n8n's pricing page, the Business plan is listed at 667 euros per month billed annually and is currently self-hosted only, and it is the tier that adds SSO and LDAP, Git-based environments and log streaming. Enterprise is priced by quote for self-hosted or cloud. Confirm with n8n which plan your SSO, Git and log streaming requirements actually land on, because that decision is the largest recurring line item for a self-hosted team.
Scaling n8n moves cost into components. In queue mode, the main instance, Redis and the worker pool each need hosting, and workers read and write workflow data in PostgreSQL, which must be sized and backed up. Running queue mode on SQLite is not recommended, so budget for a managed or self-run PostgreSQL service from the start. Multi-main high availability is restricted to Enterprise self-hosted deployments, so an HA requirement adds a paid license on top of the infrastructure. Kestra's open-source edition runs as a single-server default, and its Enterprise Edition adds a high availability architecture using Kafka plus Elasticsearch, Redis, AMQP or GCP Pub/Sub queue backends, worker groups and task runners. That stack is a larger recurring footprint than most teams expect. Kestra Enterprise pricing is not published in the supplied facts, so obtain it from Kestra in writing.
Engineering skill and support shape the rest of the cost. Visual n8n flows can be built and reviewed by operations staff, while Kestra's declarative YAML flows, Git integration and plugin configuration usually need engineers who are comfortable with pipelines and infrastructure. Both platforms carry one-time costs for design, build and any migration, and recurring costs for hosting, maintenance and upgrades. Kestra 2.0 is a major release with breaking changes and a migration guide, so plan the upgrade effort for any 1.x estate. Ask vendors and partners for: the edition and plan named in the quote, every component in the HA or queue design, the support tier and SLA included, the upgrade and patch commitments, and which features are excluded. Partners such as DeployOpen quote fixed scope from written requirements.
Moving a workflow estate from n8n to Kestra or back
This sequence turns an existing n8n estate into a Kestra inventory, plugin mapping, rebuilt triggers and parallel-run cutover, and it works in either direction once the same inventory and mapping are reused.
Inventory every workflow, trigger and credential
Export the list of n8n workflows, including which are active, which trigger on schedules or webhooks, which call internal services, and which depend on credentials stored in n8n. Record the owner, the business purpose and the systems each workflow writes to. Credentials are listed by name and type only, never copied into a spreadsheet. The step is complete when every active workflow has an owner, a trigger type and a target system recorded, and the team has agreed which workflows are in scope for the first wave. Confirm whether any workflows run on a self-hosted queue mode deployment, since that affects where execution history lives.
Map each node to a Kestra plugin or script task
For each n8n node or integration in the inventory, identify the matching Kestra plugin, or decide that a script task in a supported language will carry the logic. Kestra advertises hundreds of built-in plugins for databases, cloud storage and APIs, but coverage for a specific SaaS node must be checked in the plugin catalog before work starts. Flag custom n8n nodes and any JavaScript or Python code blocks as items that must be rewritten by hand. The output is a mapping table with one row per node, a status of direct, script or rebuild, and a named owner for each row.
Rebuild triggers and schedules as YAML flows
Recreate each trigger as a Kestra flow definition in declarative YAML, covering schedules, webhooks and event triggers. Business logic moves as a sequence of tasks, but the trigger definitions are rebuilt, not transferred. Keep flow definitions in Git so changes are reviewed and version controlled, which Kestra's README lists as an integration. Test each flow in a non-production namespace with the same inputs an n8n run used. The step closes when each rebuilt flow reproduces the outputs of its n8n counterpart on recorded sample data, and the differences are logged.
Plan the change against Kestra 2.0 if targeting 2.x
If the target is Kestra 2.x, read the 2.0 migration guide before writing any flow, because 2.0 is a major release with breaking changes. The guide covers replacing ForEach and ForEachItem with a single Loop task, so any iteration logic in the mapping must be rewritten against that task. Confirm the exact current version in the Kestra releases page before pinning it, since patch releases continue on the 1.3 line. The output is a short compatibility note that lists every task type used in the flows and its 2.0 status.
Move credentials into the chosen secrets manager
Credentials do not transfer from n8n. Recreate each one in the secrets manager the team has chosen, and reference it from the Kestra flow rather than embedding values. Kestra's open-source edition relies on manual secret and access management, while the Enterprise Edition adds external secrets managers such as HashiCorp Vault and Azure Key Vault. Confirm which option your security policy requires before this step. Verify each rebuilt connection with a read-only test call, then rotate the upstream credentials so the old n8n values are no longer valid. The step is done when every flow authenticates from the secrets manager and the old values are revoked.
Run both platforms in parallel and compare outputs
Run the rebuilt Kestra flows alongside the live n8n workflows for an agreed period, with the n8n side writing to a staging target or the Kestra side in dry-run mode where the target supports it. Compare outputs, error counts, retry behavior and timing for each flow. Confirm that webhook consumers and upstream senders can point to the new endpoints without changing their payloads. The step is complete when each in-scope flow has matched outputs on live-equivalent traffic and every mismatch has an approved fix or an accepted exception.
Cut over and retire n8n workflows in stages
Switch each workflow to Kestra in the order set in the first step, starting with the lowest-impact flows. Disable the n8n version only after its Kestra replacement has run successfully through a full business cycle that the owner has reviewed. Keep exported n8n workflow JSON and execution records under the retention rules your organization applies, and confirm with your legal and records team how long they must be kept. The output is a signed-off cutover log and a retired workflow list. The same inventory, mapping and parallel-run steps apply if the migration runs from Kestra back to n8n, with the trigger and credential rebuild reversed.
Where n8n and Kestra implementation projects usually run long
Implementation effort for both platforms follows the same arc: stand up the self-hosted stack, connect identity, set up backups and key handling, then build and test the first production flows. The overruns come from the parts that look small at the start. For n8n, the encryption key is the first thing to get right. In queue mode the main instance's encryption key must be shared with every worker and webhook processor so they can read credentials stored in the database, so a key that is lost, rotated without a plan, or set differently on one node will break executions in ways that are hard to trace. For Kestra, the open-source edition relies on basic authentication, a single-server default deployment and manual secret and access management, so the work of building a secrets process and an access model falls to your team unless you move to the Enterprise Edition.
Identity and credential migration cause most of the schedule slips. n8n SAML single sign-on is available on the Business and Enterprise plans, and Kestra SSO, SCIM and RBAC sit in its Enterprise Edition. Before scoping, map every group in your identity provider to a role in each tool, decide who owns service accounts and API tokens, and inventory the credentials that existing automations use. Credential migration often takes longer than planned because each connection has to be re-authorized and tested against the target system. Custom node or plugin work is the other common overrun. Confirm which integrations you need from the built-in catalog and which require custom code, and note that some n8n features that depend on self-hosting, such as custom nodes, are a factor in the deployment choice.
Version upgrades need their own budget line. Kestra 2.0 is a major release with breaking changes and a dedicated migration guide, including replacing ForEach and ForEachItem with a single Loop task, so flows written on the 1.3 line need review before they move. n8n's current stable line is 2.x while 1.x still receives releases, so decide which line you run and how you will test upgrades. Fixed-scope work starts from a written scope that lists the stack, identity integration, migration volume, flows and tests, and DeployOpen does not publish a price list, so ask for a quote that prices each of these items separately and states what happens if the migration inventory grows.
Questions buyers ask before choosing n8n or Kestra
What does the Sustainable Use License mean for an internal deployment?
For an internal deployment, the Sustainable Use License allows you to use and modify n8n for your own internal business purposes, so a company can run its own instance for its own workflows. It is a source-available, fair-code license, and it does not meet the Open Source Initiative definition, which matters if your policy requires OSI-approved software. The limits matter once the deployment changes shape. Distribution is allowed only free of charge and only for non-commercial purposes, so offering n8n as a hosted service to customers or reselling it falls outside the grant. Files with .ee in their name are not covered and require a valid n8n Enterprise License. Have counsel check your intended use, including any embedding in a product, against the n8n LICENSE.md.
Does SSO require a paid edition on n8n and Kestra?
Yes on both platforms, although the paid tiers differ. On n8n, SSO and LDAP are included only in the Business and Enterprise plans according to n8n's pricing page, and SAML single sign-on is available on those plans, with setup guides for Okta Workforce Identity and Azure AD. On Kestra, the open-source edition provides basic authentication only, and SSO, SCIM and role-based access control come with Kestra Enterprise Edition. Confirm that the identity provider, group mapping and provisioning model you need are covered by the exact tier you buy. Get that entitlement in writing before your access design depends on it, and ask whether the n8n Business plan's self-hosted availability matches your deployment model.
How much effort does a self-hosted queue or HA setup need?
The effort depends on the topology you choose, and the supplied facts describe components rather than hours. For n8n queue mode, the main instance handles triggers and webhooks and passes executions through Redis to worker processes, which run executions and write results to the database, typically PostgreSQL. Every worker and webhook processor needs the main instance's encryption key, so key handling becomes part of your operating procedure, and SQLite is not recommended for queue mode. Multi-main high availability is limited to Enterprise self-hosted deployments. Kestra's open-source default is a single server, and its high availability architecture, with Kafka plus Elasticsearch, Redis, AMQP or GCP Pub/Sub queue backends, sits in Enterprise Edition. Ask your platform team to size the infrastructure and runbooks for the exact topology you intend to run.
Can non-engineers build n8n flows, or do Kestra flows need YAML?
n8n is the easier fit for non-engineering builders. Its visual canvas connects more than 1,500 integrations without code, and custom JavaScript or Python can be added to a step when the visual nodes are not enough. Kestra flows are defined in declarative YAML. Kestra's YAML editor, no-code editor and AI Copilot stay in sync, so a non-engineer can work in the no-code editor, but reviewers will still read the underlying YAML. Its Git version control integration suits teams that want flow changes reviewed the way code is reviewed. Decide before rollout who owns each flow after go-live, and set naming standards, documentation and access controls so a flow built by one group can be maintained by another.
How long does migrating between n8n and Kestra take?
The supplied facts do not give a migration duration, so treat any number a vendor or partner quotes as a claim to verify against your own inventory. The time depends on the number of workflows, how many use custom code, how many depend on stored credentials or external secrets, and how many triggers and webhooks must be re-pointed and tested. Kestra 2.0 is a major release with breaking changes, including replacing ForEach and ForEachItem with a single Loop task, so flows that iterate need rewriting and retesting. Moving from n8n also means each visual flow is rebuilt as YAML and needs its own test cases. Ask for a written, inventory-based scope with a test approach, cutover plan and rollback steps before you accept any timeline.
Can our own team run n8n or Kestra without outside help?
Possibly, if your team already runs containers, databases, identity integration and secrets management and can own upgrades. Both platforms are self-hosted, so the operations work stays with you. For n8n queue mode, that includes Redis, workers and encryption key handling. On Kestra's open-source edition, authentication is basic, secret and access management is manual and audit logging is absent, so your team builds those controls. Enterprise Edition adds SSO, SCIM, RBAC, external secrets managers and audit logs. Outside help is one option. DeployOpen plans, implements, integrates, hardens, backs up, upgrades and documents self-hosted platforms inside your own infrastructure, usually under fixed-scope agreements with written deliverables, and offers retainers for ongoing support and upgrades. Assess your team against these controls before deciding.
What do n8n and Kestra cost to license and run?
Licensing and running costs are separate. n8n's Community edition is free to self-host. Its pricing page lists cloud Starter and Pro plans at 20 euros and 50 euros per month billed annually, a Business plan at 667 euros per month billed annually that is currently self-hosted only, and Enterprise at custom pricing. All plans include unlimited users, workflows and integrations, and an execution counts as one run of a whole workflow. For Kestra, ask for a written quote covering Enterprise features and high availability, since that quote is where your figures come from. Recurring costs include servers, databases, queue backends, backups, staff time and any support retainer. One-time costs include design, migration and testing. Ask each vendor for an itemized quote by license tier, support level and environment count.
