Sentry

Sentry is the leading application monitoring platform for developers, tracking errors, crashes, and performance across every platform.

Overview

Sentry gives developers actionable error tracking and performance monitoring for web, mobile, and backend applications. When something breaks, it captures the stack trace, breadcrumbs, and release context so engineers can reproduce and fix issues fast. Performance monitoring covers slow endpoints and transactions, while session replay shows exactly what users experienced. It supports 100+ platforms and languages with simple SDK integration.

Sentry earns its place in the developer toolchain by making failures actionable: every error arrives with stack traces, breadcrumbs, and the exact release that introduced it. Fixing becomes a targeted task rather than an investigation from scratch.

Session replay adds the missing human context, showing the clicks and inputs that preceded a crash. Coverage across web, mobile, and backend means one tool for the whole team, and integrations push issues into the trackers engineers already work in.

Teams commonly adopt Sentry early in a product’s life and keep it as applications scale, since setup is minutes per platform. Alert rules route problems to the right owners, and release tracking pinpoints regressions to specific deploys. Performance budgets help prevent slow features from shipping unnoticed.

Key Features

• Error tracking with stack traces, breadcrumbs, and full context
• Performance monitoring for transactions, queries, and slow endpoints
• Session replay that reconstructs user actions before failures
• Release health tracking and deploy markers for regression detection
• Alert routing to Slack, PagerDuty, Jira, and issue trackers
