UUID Generator

Generate one or many cryptographically secure UUID version 4 identifiers.

When to use the UUID Generator

Use it when you need unique identifiers for database rows, test fixtures, API keys or configuration.

Examples

  • Generate a batch of UUIDs for seed data.
  • Create a unique ID for a new service or tenant.

Common mistakes

  • Using UUIDs as secrets; they identify things but are not passwords.
  • Assuming UUIDs are sorted by time; version 4 is random.
