About Sentry

Sentry is an application performance monitoring and error tracking service for development teams. Its SDKs are added to an application to report errors, logs, replays, spans, profiles, and metrics. The homepage says these are linked by a common trace, so a developer can move from an issue to its context and then to a fix. The homepage lists many supported languages and frameworks and shows an install command for several of them.

Sentry's AI debugger, Seer, uses Sentry data such as logs, commits, traces, and stack traces to explain failures and generate patches. It also correlates pull requests with error and performance history. Sentry offers agent tracing for AI agents and an MCP server that connects tools such as GitHub, Slack, Jira, Linear, and coding agents to incident context. The homepage does not state pricing or which plans include Seer or the MCP server. The Python example sets the trace sample rate to 1.0, which captures every transaction, and the homepage recommends adjusting this value in production.
