The http status checker works like this: it requests any URL with browser-like headers, follows redirects, and reports the status code, final URL, server and timing. Everything happens on your device - the input never leaves your tab unless the tool clearly states it performs a server-side lookup.
How to use the HTTP Status Checker
Enter the full URL, domain or content the tool asks for.
Run the check - fetch-based tools query the page server-side.
Read the findings as a list, not a single score.
Fix one issue at a time and re-run to verify.

No account needed for any check

Privacy
The URL you check is fetched once so the tool can read pages that block cross-origin browser requests. No browsing history is stored, and nothing from your own device is transmitted.
Frequently asked questions
Why 403 from here but 200 in my browser?
The target site blocks datacenter/scripted requests - Cloudflare-managed sites commonly do. It does not mean the page is broken for humans.
What does the report include for a URL?
The status code, the final URL after redirects, the server identity and the response timing - the four facts that explain most "is this site up" questions.
Why might a site be up but still return an error code?
The server answers with 4xx/5xx for reasons beyond downtime - permission errors, gone pages or broken backends. The status code tells you which situation you are in.
