GlitchTip

GlitchTip is an open-source error tracking and observability platform that implements a Sentry-compatible intake API. It provides error aggregation, basic APM-style transaction visibility, and uptime monitoring via a Django backend paired with an Angular frontend.

Key Features

• Sentry-compatible event intake allowing existing Sentry client SDKs to report errors and transactions.
• Error aggregation and issue grouping with searchable issue lists and event details.
• Application performance monitoring that surfaces slow requests, database calls, and transaction traces.
• Uptime monitoring (ping-style checks) with alerts delivered via email or webhooks.
• Deployable with Docker and Docker Compose, Kubernetes Helm chart available for cluster installs.
• Backend built on Django with worker tasks via Celery; PostgreSQL is the primary data store.
• Optional cache/message broker usage of Valkey/Redis for improved performance and Celery brokering.
• Hosted SaaS offering available alongside comprehensive self-hosting docs and Docker images.

Use Cases

• Centralize and triage runtime exceptions and stack traces from web and mobile apps using existing Sentry SDKs.
• Monitor web application latency and identify slow endpoints and database calls for performance troubleshooting.
• Keep track of site uptime with scheduled pings and receive alerts when endpoints fail to respond.

Limitations and Considerations

• Some enterprise SSO workflows (notably SAML multi-tenant SSO) are a known area of ongoing discussion and work; available social/OAuth providers are supported via django-allauth but full SAML multi-tenant support is not yet standard.
• For larger deployments, Valkey/Redis is recommended for Celery brokering, caching, and sessions; Postgres-only mode is experimental and may yield lower performance.
• Feature parity with commercial Sentry varies; a few advanced grouping, fingerprinting and analytics features are under active development or improvement.

GlitchTip is suited for teams that need a budget-friendly, open-source alternative for error tracking and basic observability while retaining compatibility with Sentry client tooling. It supports both small single-server installs and larger containerized deployments with documented configuration and upgrade paths.
