About ULID
ULID (Universally Unique Lexicographically Sortable Identifier) is designed to be a better UUID.
Sortable
The leading characters are encoded from a timestamp, so ULIDs generated later sort after those generated earlier.
URL Safe
Uses Crockford's Base32 alphabet for better readability and URL safety.
No Collisions
Includes 80 bits of randomness to ensure uniqueness even within the same millisecond.
