What is a uuid generator?

A UUID generator produces universally unique identifiers — the 128-bit values that label rows, files, events, and API objects without a central authority handing out numbers. Developers need them constantly: a primary key for a new record, a request ID for a log line, an idempotency key for a payment, a filename that can't collide. The canonical online generators do one job — spit out a v4 UUID you can copy — but the tooling has moved on. UUID v7, standardised in RFC 9562, embeds a millisecond timestamp in its leading bits so the IDs are time-sortable, which makes them far kinder to database indexes than fully random v4 keys (random keys scatter inserts across the B-tree and fragment it; time-ordered keys append). A good modern generator offers both, generates them with a cryptographically secure source, formats them the way your stack wants (uppercase, no hyphens, braces for some languages), and can also decode an existing UUID to tell you its version and, for v7, when it was minted.

Common features

  • Bulk generation (pick how many at once)
  • UUID v4 (random) and v7 (time-ordered)
  • Cryptographically secure randomness (Web Crypto, not Math.random)
  • Format options: uppercase, no hyphens, braces
  • Copy a single UUID or copy them all
  • A regenerate button for a fresh batch
  • An inspector: version, variant, nil/max detection
  • v7 timestamp decoding (when the UUID was created)
  • Everything client-side — nothing uploaded
  • Light and dark themes; options remembered on the device

Real-world examples

Seeding a database

A developer generates a batch of v7 UUIDs to use as primary keys, getting time-ordered IDs that keep the index tidy as rows are inserted.

A quick unique value

Someone needs one v4 UUID for a config file or a test fixture, generates it, and copies it in uppercase with a single click.

Decoding an ID

A developer pastes a UUID from a log to confirm it's a v7 and reads off the timestamp to see exactly when the record was created.

Why FloopFloop fits uuid generator projects

A UUID tool is the kind of utility you want instant, ad-free, and yours. FloopFloop ships the generator you want — the versions you use, the formats your stack expects, the bulk export your team needs — on your own domain, with everything generated by the browser's crypto API and nothing sent anywhere. The tidy 'identifier registry' look that ships by default lists the IDs as clean monospace rows, and the whole thing is one prompt away from being whatever fits your workflow.

Build a UUID generator with two modes. Generate: choose v4 (random) or v7 (time-ordered), pick how many (1–100), toggle uppercase / hyphens / braces, and list the results as monospace rows with copy-per-row and copy-all and a regenerate button. Inspect: paste any UUID and show its version, variant, whether it's the nil or max UUID, and — for v7 — the embedded millisecond timestamp as a date. Generate with the browser's crypto API (crypto.randomUUID for v4; a 48-bit ms timestamp + random bytes for v7). Generate the first batch in an effect so the first render is hydration-safe, and remember the options in localStorage. 100% client-side.

Create a UUID / GUID generator like the popular online ones. Bulk-generate version 4 UUIDs, copy them individually or all at once, and offer uppercase and no-hyphen variants. Keep it fast and fully in the browser.

Build a developer tool that generates UUID v7 (the new time-sortable UUID that's great as a database primary key) as well as classic v4, and that can also decode a pasted UUID to tell me its version and, for v7, when it was created.

Build a UUID generator with a clean technical look — a list of generated IDs, format options, and a one-click copy — plus a dark theme.

Frequently asked questions

What's the difference between UUID v4 and v7?
v4 is 122 bits of randomness — the everyday choice when you just need a unique value. v7 puts a millisecond timestamp in the first 48 bits, so the IDs sort in roughly creation order. That makes v7 an excellent database primary key: it keeps B-tree indexes from fragmenting the way random v4 keys do, while staying globally unique.
How is this different from other UUID sites?
It's yours: it lives on your subdomain, generates everything in the browser with the Web Crypto API (nothing is sent to a server), and you can add formats, versions, or a bulk-export your team needs without ads. It also inspects UUIDs, not just generates them.
Are the UUIDs cryptographically random?
Yes — v4 uses the platform's crypto.randomUUID(), and v7's random bits come from crypto.getRandomValues(). Both draw on the browser's cryptographically secure random source, not Math.random().
Can it decode a UUID I already have?
Yes — paste any UUID into the inspector and it reads back the version, the variant, whether it's the special nil (all-zero) or max (all-F) UUID, and for a v7 it decodes the embedded timestamp into a readable date.
Is anything stored or uploaded?
No. Generation and inspection happen entirely in your browser and your format options are saved to localStorage only. The single outbound surface is the /api/health probe.
