Link Rot Checker is a tool to check whether a set of URLs are still live or can no longer be accessed (dead links / link rot). The tool sends HTTP requests to each URL and reports the results.
Link rot occurs when a URL that was previously accessible becomes invalid because the page was deleted, moved, or the site is no longer operating.
Maximum 50 URLs per process. This keeps response times reasonable and results can be reviewed quickly.
200 = live, 301/302 = redirect (still accessible), 404 = page not found, 5xx = server error. Codes outside 200–399 typically indicate a problem.
Yes. URLs that result in a redirect (3xx) and are ultimately reachable are still considered live because the content can still be accessed.
Error means the tool could not get a response from the server — possibly due to a timeout, refused connection, or DNS issue. This differs from "Dead" where the server responds but with a failure code (404, 410, etc.).
No. This tool checks URLs publicly without authentication. URLs that require login will likely be reported as error or redirected to a login page.
Yes. The "Export Dead (CSV)" button will download a list of dead URLs to a CSV file for further action in a spreadsheet.
Accurate enough for quick checks. However, some servers may block bots so URLs that are actually live may be reported as error.
No. Checks are performed statelessly — the URLs you enter are not saved to any database.
Yes. Link Rot Checker is completely free, no login required, and with no daily usage limits.
