About the UUID Generator
The UUID (Universally Unique Identifier) Generator is a free developer utility that instantly creates highly unique, RFC 4122 compliant identifiers. Also known as GUIDs (Globally Unique Identifiers) in the Microsoft ecosystem, these 128-bit identifiers are essential for database primary keys, session IDs, and distributed systems.
Supported UUID Versions
- Version 4 (Random): The most common type of UUID. It relies on random numbers, ensuring an extremely low probability of collision (duplication). Ideal for almost all general-purpose identifier needs.
- Version 1 (Time-based): Generated using the current timestamp and the computer's MAC address (or a random node ID). Useful when you need identifiers that can be sorted by creation time.
Features
- Bulk Generation: Generate up to 100 UUIDs at once with a single click.
- Zero Server Communication: UUIDs are generated directly in your browser using secure cryptographic APIs (`crypto.randomUUID()`), meaning they are generated instantly and securely without network requests.
