Broken Link Checker
Paste a list of URLs and find out which ones are dead or unreachable.
How to use Broken Link Checker
Checks up to 20 URLs per run, fetched by our server since a browser can't reliably check cross-origin link status itself. A redirect that lands on a working page counts as reachable.
- Paste your list of URLs, one per line (up to 20).
- Click Check Links.
- See each URL's status — a working page, an error code, or unreachable.
Frequently asked questions
How many links can I check at once?
Up to 20 per run — paste one URL per line. This is meant for spot-checking a page's outbound links, not crawling an entire site.
Does a redirect count as broken?
No — redirects are followed automatically, so a link that bounces through one or more redirects to a working page shows as reachable, not broken.
Why do the checks run on your server instead of my browser?
Browsers block reading the response of a cross-origin request for security reasons (CORS), so there's no way to check another site's link status purely from JavaScript in your browser — our server fetches each URL on your behalf instead.
