Error tracking
Surface uncaught JavaScript errors and broken resources per page, straight from the tracker.
Broken pages cost you visitors silently. Quantalog forwards uncaught JavaScript errors and failed page resources so you can see which pages are breaking, and how often, without wiring up a separate error monitor.
What's captured
- Uncaught exceptions (
window.onerror). - Unhandled promise rejections.
- Failed resource loads — an image or script that 404s.
Errors are grouped by message and the page they happened on, and shown under Analytics → Errors or the JS errors Home widget, newest and most frequent first.
Privacy & limits
Only the error message and the page path are sent — never stack contents, variable values, or personal data. Each page reports at most a handful of errors so a single broken page can't flood your dashboard.
