Generate RFC 4122 compliant UUID v4 identifiers. Generate 1–10 UUIDs at once.
UUID (Universally Unique Identifier) is a 128-bit identifier that is practically guaranteed to be unique across space and time. They are used in software development to identify objects without central coordination.
This tool generates UUID v4 (random), which is the most commonly used version. Each UUID is randomly generated using cryptographically secure random values.
UUID v4 has 122 random bits, making the probability of collision astronomically low. For all practical purposes, they are unique.
GUID (Globally Unique Identifier) is Microsoft's implementation of the UUID standard. They are functionally equivalent and follow the same format.
