HTTP Status Checker

Instantly test HTTP status codes, redirect chains, SSL issues, or downtime for any public URL.

Input

Use this free HTTP Status Checker to check the http status code of any url.

About the HTTP Status Checker

An accurate HTTP response tells browsers, crawlers, and ad platforms how to treat a page. The HTTP Status Checker sends a real request to your URL, surfaces the returned code, headers, and redirect path, so you can verify deployments, troubleshoot SEO issues, and confirm uptime without opening DevTools.

How the HTTP status checker works

You give a URL and pick GET or HEAD. The probe runs through a same-origin API route, because a browser cannot read cross-origin status codes or headers. A missing scheme becomes https://; only http and https are accepted. Redirects are followed manually, up to six hops, resolving each Location value against the current URL, and a 303 See Other downgrades the method to GET as RFC 9110 requires. Every hop is logged with its code, response bodies are discarded, and each request aborts after 8 seconds. Missing reason phrases, common over HTTP/2, come from a built-in table; the notes flag 4xx/5xx, Cache-Control, Expires and Retry-After.

Why Teams Rely on It

Follows redirect chains and reports each hop so you can spot loops or mixed protocols.
Runs outside of your browser cache, giving you the true server response seen by crawlers and ad bots.
No installation required—perfect for quick QA during releases or when assisting non-technical stakeholders.

How to Use the HTTP Status Checker

1

Enter the full URL, including protocol (https://). Example: `https://minitoolstack.com/robots`.

2

Click Run Tool to fetch the page from our serverless probe. We follow redirects to show every hop (301, 302, 307, etc.).

3

Review the final status code and notes. A 200 means success, 3xx indicates a redirect, 4xx points to client errors (missing pages, auth required), and 5xx means the origin server failed.

4

Use the results to decide your next action: fix redirect loops, update internal links that point to 404s, or alert your infrastructure team if a 500 persists.

5

Optional scenarios: check canonical URLs before launching a campaign, validate CDN purge rules, or confirm that maintenance pages return 503 with `Retry-After`.

Common Mistakes to Avoid

Testing URLs without the protocol (`www.example.com`); always include https:// to avoid DNS errors.
Expecting private intranet or localhost URLs to load. The checker must reach the site over the public internet.
Treating any 3xx as a failure. Permanent (301) and temporary (302/307) redirects are healthy if they point to the intended destination.
Confusing 401 (auth required) with 403 (forbidden). If you see these codes, confirm credentials or firewall settings rather than changing the page itself.

FAQ

Does the tool follow redirects?

Yes. We trace each hop and return the final URL plus the status codes encountered along the way.

Can I test staging or localhost URLs?

Only publicly accessible URLs work. For internal environments, run a local curl request or expose the site via a secure tunnel.

Does it cache the response?

No. Each run makes a fresh request so you always see the current status. Results are not stored on our servers.

What do the status classes mean?

1xx = informational, 2xx = success, 3xx = redirect, 4xx = client error (bad link), 5xx = server error. Fixes differ depending on the class.
