Error Tracking
Catch bugs before your users file tickets. Uncaught exceptions, promise rejections, and console errors — all captured automatically.
Automatic capture
Add one script tag and uncaught exceptions, unhandled promise rejections, and console errors are captured automatically.
Stack traces included
Every error comes with a full stack trace, file path, and line number so you can pinpoint the issue immediately.
Deduplicated & rate-limited
Identical errors are grouped together and rate-limited so you see each issue once, not a thousand times.
See errors as they happen
Himetrica's error feed shows you every error in real time, grouped by message, with occurrence counts and timestamps. Click any error to see its full stack trace and context.
TypeError: Cannot read 'map' of undefined

ReferenceError: window is not defined
One script tag to add
Drop errors.js alongside your main tracker — no build steps, no config. Errors start flowing in automatically, including console.error interception.
<!-- Add after your tracker -->
