How to use Redirect Checker
- Give Redirect Checker response headers, cURL -i output or a HAR to work from.
- Press Analyze to run it locally in your browser.
- Use the parsed redirect chain and security-header audit Redirect Checker produces — nothing was uploaded.
About this tool
Everything Redirect Checker does happens on your own device. Paste the headers, curl -i output or HAR you captured and Redirect Checker maps the hops and status codes locally.
Because browsers block cross-origin live requests, Redirect Checker works from captured headers rather than fetching the URL itself. It behaves the same on desktop and mobile, with nothing stored remotely.
Frequently asked questions
What does Redirect Checker do?
Use Redirect Checker to check your input without installing anything; everything happens client-side.
Do I need an account for Redirect Checker?
No — Redirect Checker needs no account, sign-up or installation.
Is my input private in Redirect Checker?
Yes — your input never leaves your device; Redirect Checker does all the work in your browser.
Why can't Redirect Checker fetch a live URL itself?
Browsers block cross-origin requests (CORS), so Redirect Checker analyzes response headers, curl -i output or a HAR you capture and paste — all locally.
Does Redirect Checker work offline?
Once the page has loaded, Redirect Checker keeps working with no network connection.
