ID Generator — UUID, NanoID & CUID

A unified ID generation toolkit. Generate UUID v4 (128-bit, RFC 4122), NanoID (compact, URL-safe, configurable alphabet), and CUID2 (sortable, collision-resistant) — all in one place. Batch generate up to 100 IDs at once. Perfect for database keys, distributed systems, API tokens, and test data. Everything runs in your browser using the Web Crypto API.
