Create ULID IDs instantly
Generate lexicographically sortable ULIDs with timestamp-based randomness and optional monotonic mode.
About ULID
ULID (Universally Unique Lexicographically Sortable Identifier) encodes a timestamp in Crockford's base32 followed by random bytes. The result is a globally unique, URL-safe ID that sorts chronologically. Enable monotonic mode to avoid collisions when generating multiple IDs within the same millisecond.
