Which fits: Sentry or SigNoz for error tracking and observability
Sentry fits teams whose main need is mature error grouping, release tracking and a broad SDK ecosystem, while SigNoz fits teams that want exceptions, traces, logs and metrics in one self-hosted OpenTelemetry tool. If your renewal is driven by error workflows such as issue assignment, regression detection across releases and wide client coverage, Sentry's product is built around that job. If the renewal is driven by fragmented tooling, with errors in one product, traces in another and logs in a third, a unified stack deserves a closer look. The decision turns on which matters more to your engineers day to day: error workflows or a single telemetry model. It also depends on your OpenTelemetry readiness. Check how many services already emit OTLP, whether your SDKs can export to a Collector, and whether exceptions are captured as OpenTelemetry events or only through a vendor SDK.
The second deciding factor is operating capacity. SigNoz stores telemetry in ClickHouse, and its architecture places an OpenTelemetry Collector, an API server and Alertmanager in front of that database, so someone on your team must own storage sizing, upgrades, backups and scaling. The free Community Edition includes APM and tracing, log management, infrastructure monitoring, alerting and LLM monitoring, but it omits SAML, SOC 2 and HIPAA compliance, anomaly detection and prebuilt integrations, and its support is community Slack only. If your auditors require SAML, a compliance attestation or a support contract, confirm with SigNoz whether the Teams or Enterprise plan meets that requirement before you plan a migration. Those conditions are not a judgment on Sentry, which offers its own hosted compliance and support terms. They are simply the checks a regulated team should complete before committing.
Which option fits which scenario
This table maps common team situations to the option that usually fits better, along with the condition that drives the choice. Read each row against your own error volume, existing SDK footprint, compliance deadlines and residency rules. The main takeaway is that Sentry fits error-first workflows with a large SDK footprint, while SigNoz fits teams that want errors, traces, logs and metrics in one self-hosted tool.
| Scenario | Better fit | Condition that drives the choice |
|---|---|---|
| Error-first team with an existing Sentry SDK footprint | Sentry SaaS or GlitchTip | Keeping Sentry SDKs and issue grouping matters more than correlating traces and logs in one tool. GlitchTip keeps the SDKs and drops the SaaS dependency. |
| Team consolidating APM, logs and metrics | SigNoz | You want exceptions, traces, logs, metrics and alerts in one OpenTelemetry-native self-hosted platform rather than separate error and APM tools. |
| Team needing SAML on day one | Sentry SaaS or SigNoz Teams or Enterprise | SigNoz lists SAML only on its Teams and Enterprise plans, so a self-hosted Community Edition deployment would not include it. Confirm current plan terms before deciding. |
| Team needing formal compliance evidence on day one | Sentry SaaS, or SigNoz with an independent assessment plan | SigNoz's Community Edition does not include SOC 2 or HIPAA compliance. Self-hosting shifts control evidence to your team, and an independent auditor must issue any report. |
| Team with strict data residency inside its own network | SigNoz self-hosted | All telemetry stays in ClickHouse on infrastructure you control. Confirm where your exceptions and user data are stored and who can access the database. |
| Team already standardized on OpenTelemetry | SigNoz, with OpenTelemetry Collector pipelines | Your SDKs and Collector configuration can send data to SigNoz without vendor-specific agents, which simplifies a later move between backends. |
| Team with limited operations capacity | Sentry SaaS or SigNoz Cloud | Self-hosting SigNoz means your team runs ClickHouse, the Collector, the API server and Alertmanager, including upgrades and backups. Weigh that effort against the subscription. |
| Team needing prebuilt integrations and vendor support | Sentry SaaS, or SigNoz Enterprise | SigNoz Community Edition support is through community Slack only, and prebuilt integrations are not included. Ask for written support terms before committing. |
Where the data lives and who runs it
Each option moves the hosting, operating and identity work to a different party. Read the cards together, because the region you choose, the plan you buy and the team that runs the platform decide where telemetry is stored and who is accountable for it.
Sentry SaaS hosting and region
Sentry SaaS stores events, issues and project data in the hosting region your organization selects, and that choice determines where your error data sits. Before committing, confirm with Sentry which region applies, which data stays in it and which metadata, such as account records, tokens and audit logs, is held elsewhere. Also ask whether the region can be changed after the organization is created. Record the answers, because they decide whether this option meets your residency rules.
Self-hosted Sentry under FSL
Self-hosted Sentry is a separate option from SaaS. Its code is published under the Functional Source License, which makes it source-available under a license that is not an open-source license, so legal and procurement teams should read the terms before planning a deployment. Your team would run the full application stack, its supporting data stores, upgrades and backups, and would carry the hardware and on-call load. Evaluate it on its own terms alongside SigNoz.
SigNoz self-hosted deployment
SigNoz can be self-hosted with Docker Standalone, Docker Swarm or Kubernetes with Helm. Its architecture combines an OpenTelemetry Collector that writes to ClickHouse, an API server that serves the frontend and query APIs, and Alertmanager for alert grouping and notification. Your team operates each component, including storage sizing, scaling, upgrades and backups. Confirm which deployment method fits your current platform and who owns the ClickHouse cluster before comparing costs.
SigNoz Cloud regions and dedicated options
SigNoz Cloud operates data centers in the US, EU and India, and the region you pick sets where your telemetry is stored. Enterprise customers can also choose SigNoz Cloud Dedicated or BYOC, where SigNoz manages the service inside your own cloud account. Under BYOC, confirm which components SigNoz operates, who holds administrative access and where backups are kept. Check these details against the current pricing and plan documentation before you sign.
SSO and SAML by plan
SigNoz lists SAML as available only on the Teams and Enterprise plans, although SSO appears on every plan, including the free Community Edition. If your identity provider policy requires SAML, the self-hosted Community Edition does not meet that requirement on its own. Map how your staff sign in today, identify which protocol your identity provider uses and confirm which accounts, such as administrators and read-only users, need SSO or SAML. Document the decision for your access reviews.
Compliance evidence and who assesses it
Your own team produces compliance evidence for a self-hosted platform, including configuration records, access reviews, backup logs and change history. SigNoz's pricing page states that the Community Edition does not include SOC 2 or HIPAA compliance, so those controls and their evidence are your responsibility. Independent auditors assess the evidence, and neither SigNoz nor DeployOpen issues an audit report or certification. DeployOpen can prepare the systems, controls and evidence for that assessment.
How SigNoz open core licensing affects the decision
Before committing to SigNoz, confirm that every feature you depend on sits outside the enterprise directories. According to SigNoz's LICENSE file, code outside the ee/ and cmd/enterprise/ directories is MIT licensed, while code inside those directories falls under a separate enterprise license. That split matters because the MIT part is what you can run, modify and redistribute freely, and the enterprise part is where a commercial agreement may be required. Read the SigNoz LICENSE file yourself, then ask your legal team to review the terms for any directory you plan to build from, patch or ship inside your own images.
The Community Edition, per SigNoz's pricing page, includes APM and tracing, log management, infrastructure monitoring, alerting and LLM monitoring at no license fee. It excludes SAML, SOC 2 and HIPAA compliance, anomaly detection and prebuilt integrations, and its support is community Slack only. SSO is listed on every plan, including Community, while SAML is limited to the Teams and Enterprise plans. If your identity provider requires SAML, or your audit scope expects SOC 2 or HIPAA evidence from the vendor, the Community Edition may not meet that requirement and you should plan for a paid tier or your own controls. Ask SigNoz in writing which features are gated and confirm the current list before you size the project.
Sentry's self-hosted edition is source-available under the Functional Source License, which is a different model from SigNoz's MIT core with a separate enterprise tree. Both let you inspect code and run it on your own infrastructure, but the terms governing commercial use, redistribution and competing services differ, so the comparison is about license terms, not about which project is more open. Check Sentry's own licensing against your use case, particularly if you plan to offer the software to third parties, embed it in a product or operate it as a managed service. Your decision should rest on the license text in force for the exact version you intend to deploy.
What each option costs to run, by component
Sentry and SigNoz price different things. Sentry charges through a subscription and event quotas, while self-hosted SigNoz moves the cost to infrastructure, storage and the people who run it. The cards below separate one-time setup from recurring spend and list what to request in a written quote from each side.
Sentry subscription and event quotas
Sentry SaaS is a recurring subscription that scales with plan tier, event volume, retention and the features each tier unlocks, such as SSO. This page does not state Sentry's prices, so request a written quote for the event volume, retention period, seat count and feature tier you need. Ask whether overage charges apply when a release generates an error spike, and whether the quote covers session replay or performance data as separate line items.
SigNoz Cloud Teams usage pricing
The Teams plan starts at $49 a month including $49 of usage. Logs and traces are billed at $0.30 per GB ingested with 15-day retention, and metrics at $0.10 per million samples with 1-month retention. Your monthly cost depends on how much telemetry you send and how long you keep it, so estimate ingest volume from your current error and trace traffic before comparing with Sentry's event quotas.
SigNoz Enterprise and support tiers
SigNoz Enterprise starts at $4,000 a month and comes in three forms: SigNoz Cloud Dedicated, BYOC managed by SigNoz in your cloud account, or self-hosted with enterprise support. In the self-hosted option, your team still runs infrastructure, scaling, upgrades and backups. Ask in writing which of these items the quote covers and what response terms apply, since the free Community Edition offers only community Slack support.
Self-hosted infrastructure and storage
Self-hosted SigNoz runs on the OpenTelemetry Collector, a ClickHouse database that stores telemetry, an API server and Alertmanager. Compute and disk for ClickHouse grow with ingest volume and retention, and these are recurring cloud or data center costs. No hardware sizing figures are published on the sources reviewed here, so load-test with your own telemetry and ask your cloud provider or hardware vendor for recurring quotes before you commit.
Upgrades, backups and engineering time
Engineering time is the largest cost that does not appear on an invoice. Your team handles installation through Docker, Docker Swarm or Helm, then upgrades, backups and ClickHouse maintenance. SigNoz publishes frequent releases, with v0.146.0 the latest listed on its releases page, so plan a recurring upgrade window and a tested backup and restore procedure. Ask an implementation partner for a fixed-scope estimate covering these tasks.
On-call effort and service coverage
On-call effort is a recurring cost tied to how much of the stack you own. Self-hosted SigNoz alerting and ingestion incidents fall to your team, and the Community Edition support model is community Slack. Compare that with the response commitments in the Sentry agreement and any SigNoz Enterprise terms. Ask both vendors what availability and response commitments are written into the contract, and price the internal on-call rota against them.
How a move from Sentry to SigNoz runs
The sequence moves error and trace data from Sentry into SigNoz in stages, so each service can be verified against the old system before its alerting and telemetry are cut over. The result is a documented, reversible path agreed in writing before any production change.
Inventory Sentry projects, SDKs and alert rules
Export a list of every Sentry organization, project, environment, release and alert rule, along with the SDK and version each service uses and every integration that receives Sentry notifications, such as chat or ticketing. Your team and DeployOpen review the list together and mark which items matter for on-call. Done when each service has a row showing its SDK, owners, alert destinations and the Sentry features it relies on, such as issue assignment, release health or performance traces.
Confirm the SigNoz feature gaps
Compare the Sentry features your teams use against what SigNoz Community Edition provides. Check exception grouping and triage habits, release tracking, SSO and SAML needs, and compliance attestations, since the SigNoz pricing page lists SAML, SOC 2 and HIPAA as not included in Community Edition and support as community Slack only. Write down the gaps and the owner for each. Done when the team has a signed-off gap list that says what changes in daily work.
Add OpenTelemetry instrumentation and a Collector pipeline
Instrument the target services with OpenTelemetry SDKs, or route existing telemetry through an OpenTelemetry Collector that receives it and exports OTLP to SigNoz. Where Sentry SDKs stay in place for error capture, confirm which events flow to which system during the transition. The Collector configuration should follow the security practices for receivers and exporters, including authentication for incoming connections. Done when test traffic from one service appears in SigNoz with traces and exceptions that match what Sentry shows.
Deploy SigNoz and run it alongside Sentry
Install SigNoz in your own infrastructure using Docker or Kubernetes with Helm, sized to the data volume measured in the previous step. Keep Sentry active and send the same traffic to both systems for a defined comparison period agreed in the migration plan. Compare error counts, grouping, latency traces and log coverage for each service. Done when a written comparison shows where the two systems agree and where they differ for every in-scope service.
Re-create alert routing in Alertmanager
Translate each Sentry alert rule into a SigNoz alert and route notifications through Alertmanager, which handles deduplication, grouping and notification. Define receivers for your existing chat and on-call tools and test each route with a controlled alert. Keep Sentry alerts muted only after the matching SigNoz route has fired correctly in a test. Done when every rule from the inventory has a tested SigNoz equivalent and a named owner.
Export Sentry history that the API allows
Before decommissioning, pull issues, events and project settings from Sentry through its web API, using the region-specific host and cursor pagination while respecting rate limit headers. Store the exports in a location your retention policy covers. Be aware that historical events do not usually import into SigNoz as native records, so archive them as files for audit and reference. Done when each project has an archived export and a note of what could not be exported.
Cut over each service and retire Sentry per service
Move one service at a time: stop sending to Sentry for that service, confirm SigNoz receives its errors, traces and alerts for a monitoring period, then remove the Sentry DSN. Adjust triage routines, since Sentry's issue workflow, such as assignment and resolve-in-release, may need a different pattern in SigNoz. Done when every service has been cut over, Sentry is read-only, and the team has signed off the operating runbook.
Questions teams ask before switching from Sentry to SigNoz
What does a self-hosted SigNoz project cost in effort, and what drives it?
The main cost is engineering time, not the software, because SigNoz Community Edition is free to self-host under MIT for the code outside its enterprise directories. Effort is driven by the Kubernetes or Docker platform you already run, the number of services sending telemetry, the volume of logs and traces, retention targets, and how many alert rules and dashboards you need to rebuild. Recurring costs include the infrastructure that runs the collector, query services and ClickHouse, plus upgrades and backups that your team owns. Ask any implementation partner for a fixed-scope quote that lists each deliverable, the environments covered and the handover criteria. Compare that with your Sentry plan and event quota, and with the on-call time you would take on for storage and upgrades.
How long does a parallel run take before switching off Sentry?
The length of the parallel run depends on what you need to prove, not on a fixed period. Teams usually keep Sentry receiving events while SigNoz receives the same OpenTelemetry data, then compare exception grouping, alert behavior and trace coverage for the services that matter most. The run ends when your on-call and release owners accept the results for the services in scope. Factors that lengthen it include services that still use Sentry SDKs without OpenTelemetry, regulated alert paths that need sign-off, and release workflows that are not yet mapped. Confirm your exit criteria in writing before the run starts, and confirm the timeline with whoever delivers the work.
What skills does the team need to run SigNoz in its own infrastructure?
Your team needs working knowledge of Docker or Kubernetes, depending on the install method you choose, because SigNoz documents Docker Standalone, Docker Swarm and Kubernetes with Helm. SigNoz stores telemetry in ClickHouse, so someone must be able to operate, monitor and back up a column-oriented database, including storage sizing and query performance. OpenTelemetry knowledge is needed to instrument services, configure the OpenTelemetry Collector and map Sentry SDK data to OTLP. Some teams find that the skills gap is in ClickHouse operations, so ask whether that work is in scope for the engagement or handed to your platform team. Confirm these skills in your own environment before you commit to a date.
Can our own team do the SigNoz migration without outside help?
Yes, a capable platform team can deploy SigNoz and move services to OpenTelemetry without outside help, since the software is open source and the install guides are public. The harder parts are usually the decisions and the evidence: deciding which Sentry alert rules and release workflows must be re-created, proving parity during the parallel run, hardening the deployment, and documenting it for auditors. An outside partner can take over any of these as a fixed-scope piece, such as the build, hardening or the parallel-run test plan, while your team keeps ownership. Decide which parts you will own based on the skills you already have and your deadline.
Does SigNoz cover Sentry's issue grouping and release tracking?
SigNoz covers exceptions as part of its OpenTelemetry-native stack, but it is not a one-to-one copy of Sentry's issue grouping and release workflow, so you should test it against your own error traffic. SigNoz connects exceptions with traces, logs and metrics, which helps when an error must be read alongside request paths and infrastructure. Sentry's release health, suspect commits and issue assignment workflows may need to be rebuilt with different tools or processes. Run a sample of real exceptions from each service through SigNoz and check how groups form, how releases are tagged and how alerts route to owners. Confirm each workflow in writing before you retire the Sentry project.
What do SAML, SOC 2 and HIPAA mean for our compliance evidence?
SAML, SOC 2 and HIPAA are features and attestations that SigNoz lists for its paid plans, so they are not automatically available in a self-hosted Community Edition. According to SigNoz's pricing page, the Community Edition does not include SAML, SOC 2 or HIPAA compliance, while SAML is available on its Teams and Enterprise plans. Self-hosting does move data into your own boundary, which helps with data residency, but it does not give you a SOC 2 report or HIPAA attestation for SigNoz. DeployOpen prepares systems, controls and evidence for compliance assessments, but independent auditors and certification bodies issue the reports. Ask your auditor which controls they will test and whether your own access, logging and backup evidence will satisfy them.
Who runs the self-hosted stack, by team type
A platform team with Kubernetes experience can run SigNoz as a Helm-based deployment in its own cluster, alongside the OpenTelemetry Collector and the ClickHouse storage that SigNoz uses. The work is mostly familiar: node sizing, persistent volumes, upgrades, backup of ClickHouse data, and monitoring the monitoring stack itself. SigNoz documents Helm installs and guides for several Kubernetes platforms, which shortens the first build but does not remove the need to size storage and retention for your own telemetry volume.
- Capacity planning: Estimate ingest rate, retention and query load from your own traffic, not from a demo dataset.
- Storage operations: Own ClickHouse backups, restore tests, disk growth and retention policy.
- Upgrades: Track SigNoz and OpenTelemetry Collector releases and test them in a staging cluster first.
- Collector configuration: Manage gateway and agent pipelines, authentication and secrets as code.
- Self-monitoring: Alert when the collector, query service or storage falls behind.
Confirm with SigNoz whether the Community Edition documentation covers your target Kubernetes distribution and what changes at each upgrade. The Community Edition support model is community Slack, so an internal on-call rota must cover every incident.
A regulated team, such as one in banking, healthcare or the public sector, usually needs a documented support contract, named escalation paths and evidence for its own assurance work. SigNoz offers an enterprise path with self-hosted deployment and enterprise support, and its pricing page states that the customer's team still runs infrastructure, storage, scaling, upgrades and backups. Support therefore covers the software and its guidance, not the operation of your environment.
- Support scope: Ask which issues are covered, response targets, and whether upgrade assistance is included.
- Feature gaps: The Community Edition lacks SAML, SOC 2 and HIPAA compliance, anomaly detection and prebuilt integrations, so check these against your requirements.
- Change control: Plan patch windows and rollback steps that your change board will accept.
- Evidence: Keep configuration, access logs and backup test records for your own assessors.
- Data location: Confirm where telemetry and backups live, since exceptions and logs can carry personal data.
Request the support terms, feature list and licensing scope in writing before procurement, because the Enterprise plan and the Community Edition differ on exactly these points.
A small engineering team without spare platform capacity often prefers a managed option, such as SigNoz Cloud, so that someone else runs storage, upgrades and availability. The trade is cost and data location. SigNoz Cloud publishes its Teams plan, with per-GB ingest pricing and fixed retention windows, and it offers data centers in the US, EU and India. Running it yourself removes the usage bill but moves all of the operating work onto people who already have other jobs.
- Managed option: Compare SigNoz Cloud usage charges against the hours your team would spend on upgrades and storage.
- Retention limits: Check whether the retention periods on the plan meet your debugging and audit needs.
- Usage growth: Ingest-based charges rise with log and trace volume, so set sampling and filtering early.
- Self-hosting fallback: Confirm you can move from cloud to self-hosting without re-instrumenting services, since both use OpenTelemetry.
- Vendor terms: Ask how exported data can be retrieved if you stop using the service.
Ask for a written quote that states usage assumptions, included retention, and what is excluded from the monthly plan price.
