About UUID Generator
UUIDs (Universally Unique Identifiers) are 128-bit IDs used in databases, distributed systems, APIs, and file systems to create unique records without needing a central authority to coordinate. This tool generates cryptographically random version 4 UUIDs using your browser's built-in crypto.randomUUID() function — the same method used in production applications.
Generate one or many at once — useful for seeding databases with test data, creating fixture IDs for unit tests, provisioning identifiers for new app objects, or any situation where you need a collision-resistant unique identifier on the spot. Copy individual UUIDs or the whole batch at once.
