UUID v1 Generator: When Time Matters, Make It Unique

Ever needed a unique ID that’s not just random, but also carries a little bit of history? That’s the beauty of UUID v1. Unlike other UUIDs, this one is time-based—meaning every code you generate is stamped with the moment it was created. I built this tool for those times when you want your IDs to tell a story, to reflect the order of creation, or to help you track events as they unfold.

What I love about this generator is how it blends precision and privacy. You get a fresh, time-stamped UUID v1 with a single click, right in your browser. No data ever leaves your device, so you can use it for sensitive logs, distributed systems, or any project where order and uniqueness matter. And if you’re a developer who likes to keep things organized, you’ll appreciate how these IDs can help you trace the flow of your data.

The interface is intentionally simple. No distractions, no unnecessary options. Just open the page, hit Generate, and you’re set. Need to clear the field? One tap. Want to copy your UUID for use in a database, a log file, or a new app? The Copy button is always there, making your workflow smooth and error-free.

Whether you’re building a time-ordered event log, managing distributed systems, or just want to experiment with unique IDs, this UUID v1 Generator is your go-to. No sign-ups, no ads, no tracking—just a practical, reliable tool that respects your privacy and your time. That’s what 1tools.app is all about: giving you the right tool, right when you need it.
