UUID Generator
Generate random version 4 UUIDs (universally unique identifiers). Generate one or a batch.
What is a UUID?
A UUID (Universally Unique Identifier) is a 128-bit value used to identify information in computer systems without needing a central authority to prevent collisions. Version 4 UUIDs, generated here, are created from random numbers — the odds of a collision are so low they're considered practically unique for any real-world use.
Where UUIDs are used
Database primary keys, session tokens, distributed system IDs, request tracing, file names, and API resource identifiers all commonly use UUIDs so that multiple systems can generate unique IDs independently without coordinating with each other.
