About this tool
Redirect-Checker.org is a static, client-side tool with no backend. Redirect-Checker.org 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.
