Frequently asked
What counts as an error?
Anything the page logs to the JavaScript console during load — errors, warnings and logs — plus uncaught exceptions.
Does the page's JavaScript actually run?
Yes. It loads in real headless Chrome, so the console reflects what an actual visitor's browser would report.
Can I monitor this automatically?
Yes — this is a live demo of the URLpipe /console API endpoint. Poll it with a free API key to catch regressions.
