Documentation
What does this tool do?
A cryptographic unique identifier generator supporting modern Version 7 (time-ordered sequential UUIDs), Version 4 (cryptographically random), Version 1, and Nil UUIDs. Generates bulk batches (up to 500) with options for uppercase/lowercase, hyphens, curly braces (`{...}`), quotes, and JSON array formatting.
When should you use it?
Use this tool to generate primary keys for database records (especially UUID v7 for optimized B-tree database indexing), create correlation IDs for microservice logs, or seed mock datasets.
