UUID v7 / v4 Generator
Generate UUID v7 (RFC 9562, 2024 — timestamp-sortable, B-tree-friendly) or classic UUID v4 (purely random). v7 is the modern recommendation for database primary keys.

Why the UUID v7 Generator is different
Browser-native
The UUID v7 Generator runs entirely in your browser. Input is processed locally — never uploaded, never logged, never cached anywhere outside your device.
No artificial limits
No daily quotas, no character ceilings, no "upgrade for more" walls. Every feature is the complete feature — the same on the first use as the thousandth.
Production-grade quality
Built to the same engineering bar as paid SaaS tools — accurate algorithms, audited logic, responsive design and accessibility-tested interactions.
Common use contexts
- Database primary keys (v7 outperforms v4 in B-tree inserts)
- Distributed ID generation
- Log correlation IDs
- Anywhere v4 is currently used — upgrade to v7
Private and secure
Zero upload
All processing happens in your browser. Input is never transmitted, logged or cached.
Works offline
Once the page loads, the tool runs without an internet connection. No network calls happen during use.
No tracking
No accounts, no cookies for tool state. Only aggregate analytics count visits at the page level.
