UUID v3 Generator: When Names Deserve Uniqueness

Ever had that moment where you need a unique ID, but it has to be the same every time for the same input? That’s the magic of UUID v3. It’s not just random—it’s name-based, which means you get a consistent, repeatable ID for any namespace and name combo you choose. I built this tool for those times when you want order, predictability, and a touch of cryptographic flair in your projects.

What makes this generator special is how it gives you control. Enter your namespace UUID and a name—maybe a domain, a username, or anything you want to keep consistent. Hit Generate, and you get a UUID v3 that’s always the same for that pair. It’s perfect for distributed systems, database keys, or any scenario where you need to avoid accidental duplicates but still want things to line up across environments.

Everything happens right in your browser. No data leaves your device, so you can use this tool for sensitive or internal projects with total peace of mind. The interface is clean and distraction-free: just fill in your values, generate, copy, and go. If you ever want to start over, Clear is just a click away.

Whether you’re a developer, a sysadmin, or just someone who loves order in their digital world, this UUID v3 Generator is your reliable companion. No sign-ups, no ads, no tracking—just a practical, privacy-first tool that does exactly what you need. That’s the 1tools.app promise: tools that work for you, whenever and however you need them.
