UUID Generator

Generate universally unique identifiers (UUIDs). Supports version 4 (random) and version 7 (time-ordered, sortable). Generate single or bulk UUIDs for database primary keys, distributed systems, or any context where you need globally unique identifiers without coordination.

Count Optional

Number of UUIDs to generate

Version Optional

v4 = random, v7 = time-sorted

Frequently asked questions

What's the difference between UUID v4 and v7?

UUID v4 is fully random. UUID v7 embeds a timestamp in the first 48 bits, making them naturally sortable by creation time. v7 is better for database primary keys because sorted inserts are much faster for B-tree indexes.

Can two UUIDs ever collide?

In theory, yes. In practice, effectively never. A v4 UUID has 122 random bits, giving 5.3 x 10^36 possible values. You'd need to generate about a billion UUIDs per second for 85 years to have a 50% chance of a single collision.
