Overview
Sentry is a developer-first application performance monitoring (APM) and error tracking platform that unifies errors, logs, replays, spans, profiles, and metrics under a single trace. Instead of stitching together a dozen disconnected tools, teams get one connected view that takes them from issue to context to fix in seconds.
Millions of developers — from startups to enterprises like Disney, Instacart, Anthropic, and Vercel — rely on Sentry to catch critical issues before they merge and fix them the moment they hit production. Its lightweight SDKs drop in with just five lines of code, no agents to install, and no performance surprises.
What sets Sentry apart is its AI-powered debugging agent, Seer, which analyzes every signal — logs, commits, traces, and stack traces — to explain why code failed, not just where. It generates precise, merge-ready patches and correlates PRs against real error and performance history to catch regressions before they ship.
Key Features
- Unified Observability: Errors, logs, session replays, distributed traces, profiles, and metrics all connected by the same trace ID for instant root-cause analysis.
- Seer AI Debugger: An AI agent that analyzes every signal to explain why code failed, generates merge-ready patches, and stops bad code before it starts bad days.
- AI Code Review: Predicts and prevents the errors that matter most by correlating PRs against real error and performance history before they ship.
- MCP Server Integration: Brings full Sentry context directly into GitHub, Slack, Jira, Linear, and coding agents like Cursor and Claude.
- 5-Line SDK Setup: Drop-in SDKs for 20+ languages and frameworks (Next.js, React, Python, Go, Swift, Ruby, PHP, .NET, and more) with zero performance overhead.
Use Cases
- Full-Stack Development Teams: Catch slow queries, N+1s, and request timeouts before they become production incidents, and map every incident to the release, PR, and owner automatically.
- DevOps & SRE Teams: Monitor service
