Alive URL Checker

Paste a URL list and the checker requests each one through a public proxy, reporting the HTTP status so you can catch dead links, removed pages and hard 404s before your visitors do.

Step by step

  1. Paste one URL per line into the input box.
  2. Click Check URLs and let the progress line run.
  3. Review the badges: alive for successful responses, dead for 4xx, 5xx and network failures.
  4. Copy the plain-text output and use the dead list as your redirect or removal queue.

Tips for better results

  • Treat redirects as a to-do rather than a failure — update the link so users skip the extra hop.
  • Split long lists into batches of a few hundred URLs; public proxies throttle heavy use.
  • For a site-wide crawl with a CSV of every status code, request a broken link report instead.

Frequently asked questions

Why do some URLs show as dead when they load in my browser?

Sites that block automated requests, require cookies or rate-limit the proxy can return an error even though the page works for a human. Spot-check anything surprising before acting on it.

How many URLs can I check at once?

A few hundred per run is realistic, because each URL is requested individually and the public proxy throttles heavy use.

Is the checker free?

Yes, with no account and no charge. When you need volume, the offline report workflow uses direct requests instead of a shared proxy.
