Sentry is a developer-focused software monitoring platform that helps engineering teams understand, troubleshoot, and prevent problems in their applications. Its products connect error reports, logs, traces, profiles, metrics, and session replays, giving teams context to move from identifying an issue to fixing its cause. Sentry supports application performance monitoring, error tracking, real user monitoring, and observability for web, mobile, and game development, as well as AI applications and agents.

The platform includes tools for monitoring errors, performance, uptime, scheduled tasks, and application sessions, alongside profiling, size analysis, and integrations with services such as GitHub and Slack. Seer, Sentry’s AI debugging agent and code reviewer, analyzes application signals and code context to explain failures, suggest or generate fixes, and help identify regressions before release. Agent tracing helps teams inspect AI agent behavior, tool calls, performance, and spend.

Sentry offers SDKs for a broad range of languages and frameworks, with setup designed to take only a few lines of code.
