HTTP Status Code Generator

Generates a random real HTTP status code, drawn from the IANA registry, along with its standard meaning — useful for teaching, testing or documentation.

Seed (optional)

The same word, at the same settings, gives the same result. It goes into the address when you generate, so a copied link opens with the word in the box. A seed is for repeatability, not secrecy.

Don't repeat what I've already seen

Your result will appear here.

What you'll get

This generator draws from a hand-checked list of 14 entries. Here is a spread of 6 of them, so you can see the style before you generate:

200 OK — the request succeeded
301 Moved Permanently — the resource has a new permanent URL
400 Bad Request — the request was malformed
404 Not Found — the resource doesn't exist
418 I'm a Teapot — an April Fools' joke status code from RFC 2324
500 Internal Server Error — something went wrong on the server

A fixed sample of the list, not a live draw — your own results are picked at random from all 14, without repeating until the list runs out. IANA HTTP Status Code Registry / RFC 9110 (public/factual technical standard). Last reviewed 2026-08-17.

How to use this tool

Press generate for a status code.
Generate again for another one.

Understanding the controls

Seed (optional): A word here brings back the same code and meaning out of the fourteen on the list, and goes on doing so while the generator is unchanged. Leave it blank for a fresh draw on each press. Drawing with a word adds it to the page address, so somebody opening the copied link finds the word in the box and gets the same code on pressing the button.

Limitations and good to know

Drawn from a curated set of fourteen common codes, not the full IANA registry — which lists more than sixty across the 1xx, 2xx, 3xx, 4xx and 5xx classes. Rarer codes like 1xx informational responses are not included here.

Practical tips

Check your client distinguishes 4xx from 5xx. Retrying a 400 forever is a common and expensive bug.
Test 429 and 503 specifically; both mean slow down, and both are frequently handled as generic failures.

Entries are chosen with your browser's cryptographic random number generator, so every entry on the list is equally likely. How Generate Random works.
