Generate unique, time-sortable identifiers (ULIDs). Everything runs in your browser.
A ULID is a 26-character identifier made of a timestamp part and a random part, encoded in Crockford's base32. ULIDs sort naturally by creation time, making them a handy alternative to UUIDs.
ULID stands for Universally Unique Lexicographically Sortable Identifier. It is a 128-bit identifier made of a 48-bit timestamp and 80 bits of randomness, represented as a 26-character string in Crockford's base32.
Like a UUID it is unique, but because a ULID embeds a timestamp at the front, ULIDs sort naturally in the order they were created. That makes them handy as database keys where ordering matters.
No. ULIDs are generated entirely in your browser and are never sent anywhere. The random part uses your browser's cryptographically secure random number generator.
