Open Source Sentry Alternatives
A curated collection of the 2 best open source alternatives to Sentry.
Sentry is widely used for error tracking and application performance monitoring, but some teams need an open source alternative because they want self-hosting, lower vendor lock-in, simpler pricing, or more control over telemetry data.
The right replacement depends on what you use Sentry for today.
If you mainly need exception tracking and uptime checks, GlitchTip is a focused option that keeps the workflow familiar.

How to Choose
Start by separating error tracking from full observability. Teams that only need exception alerts, issue grouping, release context, and uptime monitoring should review GlitchTip because it stays close to the Sentry-style workflow. Teams that need distributed tracing, metrics, logs, service maps, and broader production debugging should compare SigNoz first. Before switching, check SDK compatibility, alert routing, data retention, source map upload, release tracking, performance overhead, storage growth, and whether your team can operate ClickHouse or any required backend services. A self-hosted monitoring stack can improve data control, but it also needs careful backups, upgrades, alert reliability, and capacity planning.
FAQ
What is the best open source Sentry alternative?
SigNoz is often the best fit when you want error tracking plus broader observability across metrics, traces, logs, and dashboards. GlitchTip is a better fit when you want a lighter Sentry-style error tracking workflow.
Can open source tools replace Sentry completely?
They can replace many common workflows, but you should test SDK support, alerting, issue grouping, release tracking, source maps, retention, and performance monitoring before migrating production projects.
Which Sentry alternative is best for self-hosting?
Both SigNoz and GlitchTip can be self-hosted. SigNoz is stronger for teams that want a complete observability stack, while GlitchTip is simpler when error tracking is the main requirement.
Are Sentry alternatives cheaper?
They can reduce SaaS subscription costs, but self-hosting still has infrastructure, storage, maintenance, backup, and on-call reliability costs. Compare total operating cost, not only license price.
