HTTP Status Codes Online

Updated 2026-07-09

Look up HTTP status codes online for free. Type a code — 200, 301, 404, 500, or any other — and SnapTools shows its official name, its class (1xx–5xx), and a plain-English description of what it means. Everything runs in your browser from a built-in table, so nothing is uploaded.

Status codes are the vocabulary of every API and web request, but few of us remember every one. This reference gives the exact name and meaning in a second — whether you are debugging why a request failed, deciding which code an endpoint should return, or settling a question in review. The class digit alone (4xx client, 5xx server) often points straight at the culprit.

// how to use

  1. 1 Type an HTTP status code (or part of one) into the input panel.
  2. 2 SnapTools shows the code's name, class, and meaning.
  3. 3 Copy the result, or search another code to compare.

// examples

No. The lookup runs entirely in your browser from a built-in table, so nothing you type leaves your machine.
The first digit sets the class — 1xx informational, 2xx success, 3xx redirection, 4xx client error, and 5xx server error. Knowing the class tells you immediately who is responsible for the response.
401 Unauthorized means you are not authenticated — the request lacks valid credentials. 403 Forbidden means you are authenticated but not allowed to access the resource. The lookup shows each meaning clearly.
301 Moved Permanently tells clients and search engines the move is permanent and to update their links; 302 Found signals a temporary redirect. Choosing correctly matters for SEO and caching.
Yes — alongside the everyday codes it covers the wider range such as 418, 429, and 451, with their standard names and classes.
