A UUID (Universally Unique Identifier) is a 128-bit label used for information in computer systems. This tool generates Version 4 UUIDs, which are completely random.
Why use UUIDs?
- Collision Resistant: The probability of generating the same UUID twice is astronomically low.
- Decentralized: You can generate IDs without checking a central database, making them perfect for distributed systems.
- Database Keys: Commonly used as Primary Keys in databases (like PostgreSQL or MongoDB) instead of auto-incrementing integers.
