UUID Generator

What it does

UUID Generator creates version-4 UUIDs — the globally unique identifiers used in databases, APIs, session tokens, and software development — instantly and in bulk. Tap once to get a single ID, or generate dozens at a time and copy them all with one tap. Every UUID is created on your device using a cryptographically random algorithm, so there is no server call, no account required, and no record of what you generate. Carbide's UUID Generator is completely free and works fully offline, making it perfect for developers testing locally, designers filling mockup data, or anyone who needs a guaranteed-unique string right now. Results are formatted in the standard 8-4-4-4-12 hex pattern and ready to paste anywhere.

How to use the UUID Generator

1. Open Carbide and tap UUID Generator from the Security or Developer category.
2. Choose how many UUIDs you want to generate — from one up to a hundred at once.
3. Tap Generate and see your list of version-4 UUIDs appear instantly.
4. Tap any individual UUID to copy it, or tap Copy All to grab the entire batch.
5. Tap Generate again any time you need a fresh set.

Frequently asked questions

Are the UUIDs truly unique and random?

Yes. Each one is version 4, generated using your device's cryptographically secure random number generator. The chance of a collision across trillions of UUIDs is astronomically small.

Does this tool send my UUIDs anywhere?

Never. Everything happens on your device with no network call. Carbide does not log, transmit, or store anything you generate.

Can I generate UUIDs offline?

Absolutely — the generator works with no internet connection at all, which is one of its main advantages for developers working in restricted environments.

What format are the UUIDs in?

They follow the standard RFC 4122 format: lowercase hex in the pattern xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx, ready to paste into any codebase, database, or form.
