What is the difference between 301 and 302 redirects?

A 301 Moved Permanently redirect tells browsers and search engines the resource has permanently moved to a new URL. A 302 Found redirect is temporary — search engines keep the original URL indexed. For SEO, 301 is preferred for permanent URL changes.

Why might the checker show an error for a live website?

Some servers block requests from public proxies or send different responses based on the User-Agent header. Additionally, if the URL requires authentication or has strict CORS policies, the proxy may not be able to retrieve the status. Try adding https:// to your URL if you see an error.

About the HTTP Status Checker

This tool checks the HTTP response status code returned by a web server for any given URL. It uses the allOrigins public CORS proxy to make the request from your browser without triggering cross-origin restrictions — no server-side code on ToolZeel's end is involved.

HTTP status codes are 3-digit numbers grouped into five classes: 1xx Informational, 2xx Success (e.g. 200 OK), 3xx Redirection (e.g. 301 Moved Permanently), 4xx Client Errors (e.g. 404 Not Found, 403 Forbidden), and 5xx Server Errors (e.g. 500 Internal Server Error, 503 Service Unavailable).

Common use cases include verifying that a URL resolves correctly after a deployment, checking that old URLs redirect properly after a site migration, confirming that removed pages return 404, and diagnosing server errors during debugging.

How to Use the HTTP Status Checker

Enter a URL

Type or paste a full URL including https:// (e.g. https://example.com) into the input field.

Click Check Status

Press the "Check Status" button or press Enter. The tool fetches the URL via a CORS proxy and reads the response status code.

Read the Result

The status code and its meaning are displayed with colour coding — green for success (2xx), orange for redirects (3xx), red for errors (4xx/5xx).

Frequently Asked Questions

HTTP status codes are 3-digit numbers returned by a web server in response to a request. They indicate whether the request succeeded (2xx), was redirected (3xx), had a client error (4xx), or caused a server error (5xx).

HTTP 200 OK means the request was successful and the server returned the expected content. It is the standard success response for a loaded webpage or API call.

A 301 Moved Permanently redirect tells browsers and search engines the resource has permanently moved to a new URL — link equity passes to the new URL. A 302 Found redirect is temporary — search engines keep the original URL indexed. For SEO, use 301 for permanent URL changes.

Some servers block requests from public proxies, require authentication, or enforce strict CORS policies. In these cases the proxy cannot retrieve the status code. Ensure the URL starts with https:// and is publicly accessible without a login.
