🆔 ULID Generator

Generate random Universally Unique Lexicographically Sortable Identifiers (ULID).

ℹ️ About ULID Generator

ULID (Universally Unique Lexicographically Sortable Identifier) is a modern alternative to UUID. While UUIDs are great for uniqueness, they are often random and don't sort well in databases, leading to indexing overhead. ULIDs solve this by combining a 48-bit timestamp with 80 bits of randomness.

Benefits of ULIDs:

  • Sortability: Because they start with a timestamp, they are lexicographically sortable, making them ideal for database primary keys.
  • Readability: Encoded using Crockford's Base32, which is case-insensitive and avoids ambiguous characters (like I, L, O, and U).
  • Compatibility: Can be converted to a 128-bit format (like UUID) for storage.

Use this generator to create secure, sortable IDs for your next distributed system or application.
