ULID Generator

Mint Crockford Base32 ULIDs in the browser. They sort by time, the same idea as UUID v7.

Each ID is 26 characters: a 48-bit millisecond timestamp plus 80 bits of CSPRNG randomness. Turn on monotonic if you need strictly increasing values when several are created in the same millisecond. Nothing is logged.

ULIDs sort lexicographically by time, like UUID v7. They are not UUIDs: no hyphens, Crockford alphabet (no I, L, O, or U).
