HTTP Status Code Checker

Reference HTTP status codes

HTTP status codes are the standard way a server reports the result of a request, and knowing them is essential for anyone working with the web. This tool lists the status codes with explanations, so you can look up what a code means and why it was returned.

Why understanding codes matters

A status code is the first clue when something goes wrong: a 500 points at the server, a 403 at permissions, a 301 at a redirect. Reading the code correctly saves time that would otherwise go into guessing. The codes are grouped into informational, success, redirection, client error and server error classes, and understanding both the class and the specific code turns an opaque number into a clear signal about what happened and where to look next.
