UUID and ULID batch generator

As instruções e os campos destas novas ferramentas estão disponíveis em inglês.

Generate UUID v4, UUID v7 or ULID identifiers in bounded batches.

How it works and limits

Uses browser cryptographic randomness. UUIDs follow RFC 9562; ULIDs use a 48-bit timestamp, 80 random bits and Crockford Base32. UUID v7 and ULID reveal generation time. This ULID generator does not guarantee monotonic ordering within a millisecond. Identifiers are not passwords or access tokens; enforce uniqueness in your database.

Worked example

kind: UUID v4
count: 10

Inputs start empty. Load example fills them only when you choose it. Reset clears inputs and results.

This tool runs locally. When enabled, Google manages regional privacy choices. Google code can access this page and its inputs.
