Sentry

Users and logs provide clues, Sentry provides answers. The platform helps every developer detect, trace and fix issues in code that is already running, turning a vague report that something broke into the specific request and line that caused it.

Instrumentation happens through official SDKs, and the breadth of that list is the part that matters most when picking an error tracker. The project maintains more than twenty of them, each in its own repository with its own release cycle, so a polyglot estate reports into a single place.

The official SDKs span most environments where application code runs.

• Web and JavaScript: JavaScript, Electron and React Native reach browser, desktop and cross-platform mobile apps.
• Backend languages: Python, Ruby, PHP with a Laravel package, Go, Rust, Java and Kotlin, Elixir and Clojure.
• Apple and Microsoft stacks: Objective-C and Swift, C sharp and F sharp, plus PowerShell for scripting environments.
• Systems and cross-platform: a native C and C++ SDK alongside Dart and Flutter, and a Perl client.
• Game engines: Unity, Unreal Engine and Godot Engine each get a dedicated SDK.

Documentation, a bug tracker and GitHub discussions handle bugs, feature requests and general questions, while a Discord server hosts the wider community. The interface is translated through a public Transifex project anyone can join, and contributing guidelines for the platform itself live in the docs.
