About This Tool

So, you need a UUID. Maybe you're building an app, testing something, or just curious. Whatever the reason, this random UUID generator does exactly what it says on the tin. It spits out a universally unique identifier—no fluff, no login, no tracking. Just click a button and get a string that looks like 550e8400-e29b-41d4-a716-446655440000. That’s it.

I built this because I kept needing UUIDs during development and got tired of opening a terminal or searching for a reliable site. Sometimes you just want something simple that works. This tool runs in your browser, so nothing leaves your machine. No server logs, no analytics, no nonsense.

Key Features

  • Generates standard UUIDs (version 4) that follow the official format.
  • Works offline—no internet needed after the page loads.
  • One-click copy to clipboard. Because manually selecting that long string is annoying.
  • Lightweight and fast. No heavy frameworks or bloated code.
  • No ads, no pop-ups, no “premium” upgrades. It’s free and stays that way.

FAQ

Are these UUIDs really unique?
Yeah, pretty much. Version 4 UUIDs use random or pseudo-random numbers, and the chance of a duplicate is astronomically low. Like, “winning the lottery multiple times in a row” low. For most use cases—testing, temporary IDs, local development—you’re good to go.

Can I use this in production?
Technically yes, but I’d think twice. While the UUIDs are valid, this tool isn’t built for high-volume or security-critical applications. If you’re handling sensitive data or need guaranteed entropy, use a proper backend library. This is great for quick tasks, not mission-critical systems.
