Need unique IDs for your database? The Free UUID Generator is the Best GUID Generator to rapidly create uuid v4 strings entirely offline.
A Universally Unique Identifier (UUID), also known as a GUID in Microsoft ecosystems, is a 128-bit label used for information in computer systems.
UUID v4 is generated using completely random numbers, as opposed to Version 1 which uses your computer's MAC address and the current time.
Yes. The total number of possible v4 UUIDs is 2^122. The chance of generating two identical UUIDs (a collision) is practically zero, even if you generate billions per second.
Yes, UUIDs are heavily used as primary keys in distributed databases where sequential integer IDs are difficult to manage across multiple servers.
It generates standard UUIDv4, which is based entirely on random numbers.
The chance of a collision is mathematically so close to zero that it is effectively impossible.
Yes, you can generate single UUIDs or switch to bulk mode.
Yes, this free uuid generator provides unlimited generation.
It uses secure crypto libraries to ensure true randomness.
