GlitchTip

GlitchTip is a self-hosted error tracking tool that is compatible with the Sentry SDK. If your application already sends errors to Sentry, you can point it at a GlitchTip instance instead by changing the DSN endpoint URL — nothing else in your code needs to change. Errors arrive, get grouped by type and stack trace, and appear in the GlitchTip dashboard the same way they would in Sentry.

The value proposition is straightforward. Sentry’s cloud pricing scales with event volume, which becomes meaningful for busy production applications. GlitchTip runs on your own server, stores as many events as your disk allows, and has no per-event cost. For applications generating hundreds of thousands of errors per month, the difference in cost is significant.

Error grouping and stack traces work as expected. GlitchTip clusters related errors together, shows the stack trace, logs the affected release version, and tracks how many times each error has occurred. Source maps for minified JavaScript are supported. The uptime monitoring feature adds basic HTTP endpoint checks alongside error collection, which consolidates two operational concerns in one tool.

The feature scope is more limited than Sentry. Performance monitoring, distributed tracing, session replay, and profiling are not available. GlitchTip is focused on error collection and grouping — the core use case — rather than the broader observability platform Sentry has grown into. For teams who use Sentry primarily for errors and not for performance data, that scope is sufficient.

Development is hosted on GitLab rather than GitHub, which means the star count does not reflect the project’s actual usage. It is a production-quality tool used by teams who need a Sentry alternative with no pricing ceiling.
