Search a browser-based HTTP status codes reference to find the name and meaning of any standard code from 1xx to 5xx, such as 404 Not Found or 502 Bad Gateway. The reference loads in your browser and needs no account.
HTTP status codes are grouped by their first digit: 2xx means success, 3xx is a redirect, 4xx points to a client or request problem, and 5xx points to a server problem. Knowing the group narrows a bug down fast. A searchable reference lets you type the number or a keyword and see the exact name and a short explanation of what it signals.
When an API returns 401, 403, 422 or 429, the difference matters, and it is easy to mix them up. A client-side reference loads the full list into your browser so you can look up any code offline once the page is open, with nothing sent to a server. It is free and searchable.
4xx codes indicate a client or request problem, while 5xx codes indicate a server-side problem.
Yes. You can search by the code number or by a keyword in its message.
Only to load the page. Once loaded, the reference works in your browser.
