The UUID Generator API allows you to generate unique UUIDs and GUIDs easily via HTTP requests. It supports multiple versions, including version 1, 3, 4, and 5, and can produce them in bulk formats for efficient testing and development purposes.
Build fast test tooling: generate single or bulk UUIDs for fixtures, seeds, or mock data. Make database-friendly ordered IDs with timestamp-first UUIDs to improve indexed inserts. Create deterministic IDs from names (v3/v5) so the same input always maps to the same ID. Try the decoder to inspect UUID metadata and learn how IDs were created.
