01How it works

Every missing page is a token waiting.

404.fun maps URLs that don't exist to launches that don't exist — yet. Claiming one makes both real at the same time.

Page not found

This page has never existed.

02Error directory

404 is available.
200 is alive.

Every path on 404.fun has one of two states. Unclaimed pages return an error. Claimed pages return a token. The live entries below come from a demo registry used to test the interface.
