What is a UUID?
A UUID (Universally Unique Identifier) is a 128-bit value used to uniquely identify information in computer systems.
What is the difference between UUID v1 and v4?
UUID v1 is time-based and includes your machine's MAC address. UUID v4 is randomly generated and is more privacy-friendly.
Are generated UUIDs truly unique?
UUID v4 has 2^122 possible values, making collisions extremely unlikely in practice.
Can I generate multiple UUIDs at once?
Yes, the bulk generation feature lets you create up to 100 UUIDs at once.
Is any data stored?
No. UUIDs are generated entirely in your browser.
