Is my app broken?

Paste your app's URL. We load it in a real headless browser and report the HTTP status, JavaScript errors, failed requests and blank-page problems, plus a screenshot and a fix prompt.

Understands: go to /path, click "Button", see "Text", type "hello@x.com" into Email. Chain with “then”.

3 free checks per day. We load your page once in a headless Chrome browser. No sign-up needed.
