Broken link checker

Enter a page URL and this pulls out every link on it, then checks each one for a working response.

Checks route through the same fetch relays as the rest of Crawlie, so a link marked broken occasionally means the relay was blocked rather than the link itself — worth a second look before treating a result as certain, especially for a handful of links.
