UUID Generator

Create a universally unique identifier (UUID).
Frequently Asked Questions
What is a UUID?

A universally unique identifier (UUID) is a 128-bit number used to identify information in computer systems. The term globally unique identifier (GUID) is also used, often in software created by Microsoft.

What is a UUID used for?

UUIDs are a useful tool for generating unique identifiers that can be used in a variety of contexts, including primary keys for database record identification, messaging and communication, security and authentication, distributed systems, testing and debugging, and more.

What version UUID generator is this?

This generator creates Version-1 UUIDs (using a timestamp and the MAC address of your computer). For more information on UUID versions, check out this Wikipedia article.

Why use this particular online UUID generator?

This unique ID generator is part of an actual Retool app, so you can edit it yourself. For example, you could incorporate it into a larger Retool app, and write it directly to your database.

How was this utility made?

This developer utility is powered by a real Retool app using an embedded app, which allows you to turn internal tools and utilities like this one into public, customer-facing apps. See other apps powered by Retool, like our CSV API generator, Base64 decoder, RegEx tester, and PostgreSQL mock data generator.

Is this UUID generator free to use?

Yes, it's free to use.
