Broken link checker
Every link, one scan.

A link whose final answer is a 4xx or 5xx status, a redirect chain that never lands on a page, or an address that does not respond. Redirects that end on a working page are listed separately so you can point the link straight at the final address.

Some sites block automated requests or answer them differently. The checker asks with a HEAD request first and retries with a full GET when that fails, but pages behind a login, a bot wall or a firewall can still refuse it.

Up to 150 unique links per scan, each with a 6 second timeout, and up to 10 pages on the same site when the site option is on. You can run 5 scans a minute.

A link to a #section is checked when the scan read that page: the page you entered and any pages it scanned on the same site. Anchors on other sites are not checked.

No. Localhost, private network and cloud metadata addresses are refused, and so is any redirect that leads to one. To review a site on your own machine, open it in Notemark with the browser extension.

No. The page is fetched, checked and discarded. Notemark keeps no copy of the page or the list of links.
