Generate universally unique identifiers (UUIDs) with a single click. Supports version 4 (random) UUIDs, the most widely used variant for creating unique IDs in databases, APIs, and distributed systems.
Practically no. The probability of a collision with v4 UUIDs is astronomically low — you would need to generate over a billion UUIDs per second for decades to have a 50% chance of one duplicate.
A UUID is a 128-bit value displayed as 32 hexadecimal digits in five groups separated by hyphens: 8-4-4-4-12 (e.g., 550e8400-e29b-41d4-a716-446655440000).
