GlitchTip
MITGlitchTip is an open-source, Sentry-compatible error tracking tool that replaces Bugsnag with a lightweight, self-hosted stack and zero event fees.
Open-source alternative to — compare it against:
Overview
Burke Software and Consulting launched GlitchTip in 2020 as a streamlined, self-hosted error tracking platform after upstream monitoring software transitioned to restrictive source-available terms. By reimplementing core intake APIs to accept standard Sentry SDK envelopes, the project provides reliable crash aggregation without requiring distributed cluster infrastructure. Today, it provides engineering teams an uncomplicated way to monitor application health and stack traces entirely within their private infrastructure.
Why GlitchTip instead of Bugsnag
Bugsnag is a commercial SaaS product that relies on proprietary client libraries, meters monthly event volume, and stores application telemetry on third-party cloud servers. GlitchTip operates entirely inside your own environment as a containerized stack on Docker or Kubernetes, powered by a Python ASGI web service and a PostgreSQL database. Because GlitchTip implements the standard Sentry client protocol, migrating off proprietary error collectors requires updating only a client DSN endpoint or environment variable, eliminating the need to re-instrument error handling across multiple application codebases.
Bugsnag provides a hands-off operational model with commercial support and polished mobile stability dashboards, which suits organizations that prefer paying subscription fees over running services. GlitchTip shifts operational ownership to your team: DevOps engineers must provision persistent storage, monitor background worker queues, and run database retention routines. In return, teams bypass monthly event caps, avoid per-seat licensing penalties, and keep sensitive backtraces and request parameters inside their private network perimeter.
What it does well
- Accepts telemetry from standard Sentry SDKs across Python, JavaScript, Go, Ruby, and Java without requiring custom client libraries.
- Operates on modest hardware, requiring only a PostgreSQL instance and a background worker rather than complex streaming pipelines.
- Groups exceptions by fingerprint with stack traces, environment tags, breadcrumbs, and request headers for rapid incident triage.
- Ingests OpenTelemetry logs and provides uptime checks with ping and SSL certificate expiration alerts in a unified dashboard.
- Supports optional hot and cold storage tiering that archives aged event records into Parquet files for DuckDB queries.
