Engineered for performance
Everything you need to maintain a five-star frontend experience.
Error Tracking
Smart fingerprinting groups duplicate errors automatically. Resolve, merge, ignore, and assign issues to owners with full breadcrumb context.
Session Replay
Replay exactly what the user saw when the error occurred. No guesswork — scrub through DOM mutations frame by frame.
Performance Monitoring
Track web vitals and custom performance metrics from real users. Spot regressions before they become support tickets.
Cron Monitors
Monitor scheduled jobs with check-in pings. Get alerted when a job is late, fails, or never runs. Public status page included.
