A tool to generate Universally Unique Identifiers (UUIDs), also known as Globally Unique Identifiers (GUIDs). Whether you need version 1 (time-based), version 4 (random - most common), or the new version 7 (time-ordered sortable), this tool provides compliant identifiers instantly. Essential for database primary keys and distributed systems.

Preguntas Frecuentes

What is the difference between v4 and v7?

v4 is completely random. v7 includes a timestamp, making it 'sortable' by time (database friendly), while still retaining uniqueness. v7 is rapidly becoming the new standard for databases.

Can UUIDs collide?

Theoretically yes, practically no. The probability of a collision in v4 is 1 in 2^122. You would need to generate 1 billion UUIDs per second for 85 years to have a 50% chance of a single collision.

Is this a GUID?

Yes, UUID and GUID are synonymous. GUID is simply Microsoft's implementation of the UUID standard.
