Generate secure Version 4 or Version 7 UUIDs instantly.
A UUID (Universally Unique Identifier) is a 128-bit identifier that's guaranteed to be unique across space and time. Version 4 UUIDs are generated using random or pseudo-random numbers, making them ideal for distributed systems where uniqueness is crucial. Version 7 UUIDs are generated using a combination of timestamp and random numbers, which make them suitable for use in distributed systems where time-based ordering is important.
