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.
