What is ULID Generator?
ULID Generator creates Universally Unique Lexicographically Sortable Identifiers. Unlike UUIDs, ULIDs are sortable by time, use a base32 encoding which omits ambiguous characters (I, L, O, U), and pack a millisecond-precision timestamp with random data into a 128-bit structure.
Key Benefits
- Lexicographically sortable
- 128-bit compatibility with UUID
- URL-safe without special characters
- Bulk generation (up to 100)
Common Use Cases
- •Database primary keys
- •Event sourcing systems
- •Log line identifiers
- •Distributed systems
- •Time-series data
