About this tool
HTTP status codes are the three-digit numbers a server sends with every response, grouped by their first digit: 2xx means success, 4xx means the client did something wrong, and 5xx means the server failed. This tool explains common codes from a built-in table, and says honestly when a valid code is not in that table instead of guessing a meaning.
Frequently asked questions
What does a 404 actually mean?
The server understood the request but could not find the requested resource; it does not by itself say the whole site is down.
What if my code is not in the table?
The tool still gives its category from the first digit and states plainly that the exact meaning is not in the built-in table.
