Modern frontend monitoring

About LogRocket

LogRocket is the frontend-focused observability platform that lets you watch video-like replays of user sessions to see exactly what happened when something went wrong. Unlike backend-focused monitoring (Datadog, New Relic), LogRocket captures the complete frontend experience: DOM state, network requests, console logs, and user interactions, then replays them as a video. When a user reports a bug, you can watch their exact session instead of asking 'can you reproduce it?' Key features include session replay with pixel-perfect DOM reconstruction, error tracking with stack traces and session context, performance monitoring for Core Web Vitals, and product analytics. Free tier is limited to 1,000 sessions/month; Team ($99/mo) adds 10,000 sessions and more features. The SDK works with React, Vue, Angular, and vanilla JS. Privacy controls let you mask sensitive data. Limitations: can add ~100KB to bundle size and minor performance overhead. Best for debugging complex frontend issues, understanding user behavior, and teams where 'it works on my machine' is a constant problem.
