Sentry Has a Free API That Catches Errors Before Your Users Report Them

Sentry catches errors in production, shows you the stack trace, the user's browser, the request that caused it, and which deploy introduced it. Quick Start npm install @sentry/node # or @sentry/react, @sentry/nextjs import * as Sentry from ' @sentry/node ' Sentry . init ({ dsn : ' https://your-dsn@sentry.io/123 ' , tracesSampleRate : 0.1 // 10% of transactions }) That's it. Unhandled errors are now captured automatically. What You See When an Error Occurs Full stack trace with source maps User info (browser, OS, IP) Breadcrumbs (what happened before the error) Release tracking (which deploy caused it) Affected user count Performance Monitoring // Automatic for HTTP requests, DB queries // Manual for custom operations: const transaction = Sentry . startTransaction ({ name : ' processOrder ' }) // ... your code transaction . finish () Free Tier 5K errors/month 10K transactions/month 1 team member 30-day retention Sentry vs LogRocket vs Datadog Feature Sentry LogRocket Datadog Error track
