How it works
Free UUID and GUID generator for version 4 and version 7. Create one id or a bulk list from cryptographic randomness, then inspect a UUID to see its version, variant, and v7 timestamp.
- 01
Choose v4 or v7
Use v4 for a random id. Use v7 when the id should sort by time.
- 02
Set how many you need
One is enough for a single record. Raise the count for a fixture or a migration.
- 03
Paste an existing UUID to inspect it
The version and variant are read from the bits. A v7 id also shows the UTC time it was minted.
