What is it?

Sentry is a debugging platform for developers. It captures errors and performance data from applications so teams can see what broke, where it happened, and what led up to it. The project provides issue details, distributed traces, a trace explorer, session replays, logs, uptime monitoring, and AI-assisted analysis through its Seer feature.

The platform is paired with a large set of official SDKs covering JavaScript, Python, Go, Rust, Java/Kotlin, Ruby, PHP, Swift, C#, Flutter, Unity, Unreal Engine, Godot and more. Applications send events to a Sentry server, which groups related errors into issues for triage.

The repository contains the server application itself, written primarily in Python and built with Django. It is licensed under a fair-source license and is also offered as a hosted service at sentry.io.

  • 05Ships official SDKs for many languages, frameworks and game engines.

Use cases

  • Finding and diagnosing production exceptions in web or mobile applications.
  • Tracing slow requests across services to locate performance bottlenecks.
  • Self-hosting an error monitoring backend instead of using a hosted service.
  • Monitoring uptime and frontend behavior alongside backend errors.

Things to know

  • The README gives no install or run commands, so setup is not described here.
  • License is listed as NOASSERTION, so the license terms are unclear from the metadata.
