About this tool
Everything Check Website Status Online does happens on your own device. Check Website Status Online 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. It behaves the same on desktop and mobile, with nothing stored remotely.
