JavaScript Error Tracking

Every error caught, de-obfuscated, and explained. Upload source maps to see real file names and line numbers. Errors are automatically grouped so you focus on impact, not noise.

Source Map

De-obfuscation

Minified stack traces are useless. Upload your source maps and every error gets de-obfuscated automatically — real file names, real line numbers, real function names. Debug production errors as if you were reading your source code.

Before (minified):

              TypeError: Cannot read property 'id'

                at a.js:1:4523

                at n (vendor.js:1:89012)

                at Object.t (main.js:1:2341)

After (with source maps):

              TypeError: Cannot read property 'id'

                at processPayment (checkout.js:142:18)

                at handleSubmit (cart.js:89:5)

                at onClick (Button.jsx:23:12)

Automatic

Grouping

Errors are fingerprinted by their symbolicated stack trace and grouped automatically. See "523 occurrences across 89 sessions" instead of 523 individual alerts. Focus on impact.

Session

Context

Click any error to see exactly what the user did. The full session timeline — page views, clicks, navigations — gives you the context that stack traces alone never provide.

Spike

Alerting

Get notified the moment a new error type appears or an existing error spikes. Route alerts to Slack, email, or webhooks. Catch regressions before your users report them.
