Sentry

Sentry makes application monitoring software for developers and software teams. It collects errors and performance data from running code so engineers can find the cause of a problem and fix it quickly.

What Sentry offers

• Error tracking — catches exceptions across the whole stack with context about each one.
• Performance monitoring — flags slow queries, slow requests and timeouts.
• Tracing, logs and replays — errors, logs, replays, spans, profiles and metrics connected through the same trace.
• Seer — an AI debugger and code reviewer that analyses issues and proposes fixes before and after release.
• Agent tracing — shows unexpected output and bad tool calls from AI agents.
• Integrations — links to GitHub, Slack, Jira and Linear, plus an MCP server for coding agents.

Who it works with

Software developers and engineering teams of any size. The company says it processes billions of exceptions daily from well-known internet products.

Key facts

• Set-up: added with an SDK, with no agents to install
• Incident mapping: ties issues to the release, pull request and owner
