About this tool
Web Status Checker is a static, client-side tool with no backend. Paste the headers, curl -i output or HAR you captured and Web Status Checker maps the hops and status codes locally.
It also audits the final response for security headers such as HSTS, CSP and X-Content-Type-Options. Your input never leaves the page, and no account or install is required.
Frequently asked questions
What does Web Status Checker do?
Web Status Checker runs entirely on your device: add your input, and it checks it locally in real time.
Do I need an account for Web Status Checker?
No — Web Status Checker needs no account, sign-up or installation.
Is my input private in Web Status Checker?
Yes — your input never leaves your device; Web Status Checker does all the work in your browser.
Why can't Web Status Checker fetch a live URL itself?
Browsers block cross-origin requests (CORS), so Web Status Checker analyzes response headers, curl -i output or a HAR you capture and paste — all locally.
Can I use Web Status Checker without a connection?
Yes — after the first load Web Status Checker runs entirely offline.
