Need unique IDs for keys, tokens or test data? Generate as many UUID v4 (or short random IDs) as you want, in one click — no server involved.
When you're building something, you constantly need "a unique thing" — a row id, a session token, a test user name. UUIDs are the boringly reliable answer, and this tool hands you a batch.
Pick UUID v4 (the standard 36-character kind) or a Short ID (8 characters, easier to read), say how many, and generate. Great for seeding a database or labelling samples.
It's the small utility devs keep open: no spinning up a script just to get three ids.
Random and local — the IDs are made in your browser with the crypto-grade generator, never stored or sent. (Anonymous analytics only — privacy policy.)
Quick tip: UUIDs are unique, not secret. Don't use them as passwords or unguessable tokens for security — use a proper random token for that.
Choose how many IDs and the type (UUID v4 or Short ID), click Generate, then Copy all to grab the list.
