What is UUID / GUID Generator?
Universally Unique Identifiers (UUID) or Globally Unique Identifiers (GUID) are 128-bit labels used for information in computer systems. This tool allows developers to generate single or bulk UUIDs across version 4 (random cryptographically secure), version 1 (timestamp & node), and version 7 (Unix epoch time-ordered).
Key Features
Support for UUID v4 (Standard Cryptographic Random), v1 (Timestamp), and v7 (Time-ordered)
Generate up to 500 UUIDs at once with customizable quantity
Toggle uppercase/lowercase formatting and hyphen inclusion
Quick copy individual or all generated UUIDs to clipboard
Download results as plain text (.txt) file
Common Use Cases
- Generating primary keys for relational (PostgreSQL, MySQL) and NoSQL databases
- Creating unique transaction IDs and correlation IDs in microservices
- Mocking database seeds and test fixtures
- Generating unique asset identifiers for S3 and CDN uploads
Frequently Asked Questions
UUID v4 is completely pseudo-random. UUID v7 combines a 48-bit Unix timestamp with random bits, making it time-sortable and optimal for database index performance (B-tree indexing).
