About this tool
URL Redirect Checker runs entirely in your browser. URL Redirect Checker reconstructs a redirect chain and status codes from response headers, a curl -i dump or a HAR you capture in DevTools.
It also audits the final response for security headers such as HSTS, CSP and X-Content-Type-Options. Nothing you enter is uploaded, and it keeps working offline once the page has loaded.
Frequently asked questions
How do I use URL Redirect Checker?
URL Redirect Checker runs entirely on your device: add your input, and it checks it locally in real time.
Do I need an account for URL Redirect Checker?
No — URL Redirect Checker needs no account, sign-up or installation.
Does URL Redirect Checker upload my data?
No — URL Redirect Checker processes everything locally in your browser, so nothing you enter is uploaded or stored.
Why can't URL Redirect Checker fetch a live URL itself?
Browsers block cross-origin requests (CORS), so URL Redirect Checker analyzes response headers, curl -i output or a HAR you capture and paste — all locally.
Does URL Redirect Checker work offline?
Once the page has loaded, URL Redirect Checker keeps working with no network connection.
