ULID Generator
Generate Universally Unique Lexicographically Sortable Identifiers — time-ordered, URL-safe 26-character IDs.
About ULIDs
A ULID is a 26-character string using Crockford Base32 encoding. The first 10 characters encode the millisecond timestamp, and the last 16 characters are random. ULIDs are monotonically sortable, URL-safe, and case-insensitive — a great alternative to UUID v4.
