About this tool
There is no server behind HTTP Status Code Checker. Paste the headers, curl -i output or HAR you captured and HTTP Status Code Checker maps the hops and status codes locally.
Because browsers block cross-origin live requests, HTTP Status Code Checker works from captured headers rather than fetching the URL itself. Nothing you enter is uploaded, and it keeps working offline once the page has loaded.
Frequently asked questions
How do I use HTTP Status Code Checker?
HTTP Status Code Checker lets you check your input right in the browser, with the result shown instantly and nothing uploaded.
Do I need an account for HTTP Status Code Checker?
No — HTTP Status Code Checker needs no account, sign-up or installation.
Is my input private in HTTP Status Code Checker?
Yes — your input never leaves your device; HTTP Status Code Checker does all the work in your browser.
Why can't HTTP Status Code Checker fetch a live URL itself?
Browsers block cross-origin requests (CORS), so HTTP Status Code Checker analyzes response headers, curl -i output or a HAR you capture and paste — all locally.
Can I use HTTP Status Code Checker without a connection?
Yes — after the first load HTTP Status Code Checker runs entirely offline.
