UUID v7 Generator
Generate version 7 UUIDs, the modern time ordered variant that embeds a Unix millisecond timestamp in its most significant bits followed by random data. Because the leading bits increase over time, v7 UUIDs sort in roughly the order they were created, which gives databases much better index locality than fully random v4 UUIDs while keeping the near guarantee of uniqueness. That makes them an excellent choice for primary keys, event IDs and any records where insertion order and efficient range scans matter. This generator uses your browser secure random source for the random portion, so the values are suitable for real use. Choose how many you need and copy them all at once. Everything is created locally in your browser and never sent to a server.

Frequently asked questions
How is UUID v7 different from v4?
UUID v7 embeds a Unix millisecond timestamp in its leading bits, so the IDs are time-ordered and sortable, unlike the fully random v4.
Why use v7 for database keys?
Because the values increase over time, inserts stay close together in the index, improving locality and reducing page fragmentation compared to random UUIDs.
Can I generate several at once?
Yes. You can create a batch of v7 UUIDs and copy the list.
