Error logs

Track JavaScript errors with stack traces, occurrences and the sessions they affect.

Spectry captures client-side errors from real visitors so you can find and fix what breaks in production. Enable error collection in Settings → Features. View them under Logs.

Error logs

What's captured

  • Uncaught exceptions, unhandled promise rejections, and console errors/warnings.
  • The message and a parsed stack trace (file, line, column, and whether each frame is in your code).
  • Context: URL, browser, device, country, session ID and first-touch attribution.

Identical errors are grouped (fingerprinted) and rate-limited so a single noisy error doesn't flood your logs.

Filtering

Filter by date, browser, country, URL path, error type, status, session ID and mechanism (uncaught exception, unhandled rejection, console error/warn).

Error detail

Click an error to see the full message and stack trace, browse all of its occurrences, view a volume-over-time chart, and jump to session replays where it happened. Mark an error as Ignored to hide noise, or Open to track it.

Set up an alert or the error email digest so new errors reach you without checking the dashboard. Digest recipients are configured under Settings → Error alerts.
