Sentry
Application monitoring that catches errors before your users report them
Overview
Sentry has become the standard for production error monitoring, and for good reason: it captures errors with the full context needed to reproduce them - stack traces, breadcrumbs, user actions, browser details, and associated git commits. When something breaks in production, Sentry tells you exactly what happened and why.
Performance monitoring extends Sentry beyond error tracking. Trace slow transactions from frontend through API to database, identify bottlenecks, and set performance budgets that alert when user experience degrades. The combination of error tracking and performance monitoring gives you a complete picture of application health.
Session replay lets you watch recordings of user sessions where errors occurred. Instead of guessing what the user did before an error, you see exactly what they saw - clicks, navigation, scroll behavior - leading to the error. This context reduces debugging time dramatically.

Why We Recommend Sentry
Sentry is the first monitoring tool we add to every project. The error context, session replay, and performance traces have saved countless debugging hours. If your application has users, it should have Sentry.
