About ULID Generator

Generate ULIDs (Universally Unique Lexicographically Sortable Identifiers) for modern database applications and distributed systems. ULIDs combine the uniqueness of UUIDs with the sortability of timestamps, making them perfect for database primary keys that need chronological ordering.

Unlike standard UUIDs, ULIDs are lexicographically sortable and encode timestamp information in the first 48 bits, allowing for efficient database indexing and natural chronological sorting. The remaining 80 bits provide randomness for uniqueness, ensuring collision-free identifiers across distributed systems.

ULIDs use Crockford's Base32 encoding, making them case-insensitive, URL-safe, and more compact than UUIDs. Perfect for modern applications requiring both unique identification and time-based sorting, including event sourcing, logging systems, distributed databases, and microservices architectures.
