About this tool
There is no server behind HTTP Status Checker. HTTP Status Checker reconstructs a redirect chain and status codes from response headers, a curl -i dump or a HAR you capture in DevTools.
Because browsers block cross-origin live requests, HTTP Status Checker works from captured headers rather than fetching the URL itself. Your input never leaves the page, and no account or install is required.
Frequently asked questions
How do I use HTTP Status Checker?
HTTP Status Checker runs entirely on your device: add your input, and it checks it locally in real time.
Do I need an account for HTTP Status Checker?
No — HTTP Status Checker needs no account, sign-up or installation.
Where is my data processed by HTTP Status Checker?
Entirely in your browser — HTTP Status Checker keeps your data on your own machine and sends nothing anywhere.
Why can't HTTP Status Checker fetch a live URL itself?
Browsers block cross-origin requests (CORS), so HTTP Status Checker analyzes response headers, curl -i output or a HAR you capture and paste — all locally.
Does HTTP Status Checker work offline?
Once the page has loaded, HTTP Status Checker keeps working with no network connection.
