UUID / ULID Generator

Generate v4 / v7 / ULID / NanoID, or paste an existing ID to see its version and whether a timestamp can be extracted.

Parsed

Notes

v7 and ULID are time-ordered — friendlier as a database primary key than v4 (less page splitting).
ULID uses Crockford base32 (no I/L/O/U), 26 characters, sortable as a string.
Generated with crypto/rand. Nothing is stored or logged.
