Paste the URLs you want to check, one per line
Paste a list of URLs above (one per line) and click "Check Links" to see which ones respond and which are broken. Note: due to browser CORS restrictions, many cross-origin responses will show as "CORS blocked / unknown" rather than a precise status code — use this as a quick sanity check, not a guaranteed crawl.
Auditing a page's outbound links usually starts with actually collecting every link on that page first, which is tedious enough by hand that a dead link buried deep in an old post routinely goes unnoticed for months. This tool scans an entire webpage automatically, finding every outbound link on it and checking each one's HTTP status without requiring the list assembled or pasted in beforehand.

Useful for auditing a single page's links automatically after a site redesign to catch anything that broke, finding a dead link buried in an old blog post without manually collecting every URL on the page first, or confirming every outbound link on a page actually resolves before it's shared widely.
