GlitchTip

GlitchTip is the lightweight Sentry alternative that uses Sentry's own SDKs. Swap one environment variable (the DSN endpoint) and your existing Sentry instrumentation starts sending errors to GlitchTip instead. Error grouping, deduplication, and a searchable issue queue cover the core workflow. Performance monitoring is included.

Self-hosting needs just 256MB RAM for a minimal Docker setup with PostgreSQL. No Redis required for small deployments. One-click deploys are available on PikaPods and Railway. The Django backend keeps things simple and the unlimited projects/team members policy means no per-seat billing surprises.

Small teams who only need error tracking without Sentry's full observability suite save real money here. Solo developers get production error monitoring for free. Teams outgrowing Sentry's free tier get unlimited events on self-hosted for the cost of a small VPS.

The catch: the feature gap with Sentry is real. Session replay, profiling, AI-powered issue triage, and advanced performance tracing are all absent. GlitchTip covers core error aggregation well, but teams relying on Sentry's full platform will notice what's missing. Also hosted on GitLab, not GitHub, which means smaller community visibility.
