Frequently asked questions

Why does this need to run on a server instead of my browser?

Browsers block cross-site requests from reading another site's response status (CORS), so checking arbitrary URLs has to happen server-side. Nothing about your list is stored afterward, it's only used to make the checks for that one request.

What counts as "broken"?

Any response that isn't a 2xx success status, including 404 (not found), 500 (server error) and connection failures/timeouts. Redirects (3xx) are followed automatically and shown as OK with the final URL noted.

Is there a limit?

Up to 30 URLs per check, to keep results fast.
