How to use / Notes

How to use

  1. Choose the ID type (v4, v7, ULID, name-based v3/v5, and more).
  2. Set the quantity and generate.
  3. Copy the generated IDs at once.

Notes

  • v4 is random, while v7/ULID are time-sortable.
  • Name-based IDs (v3/v5) always produce the same ID for the same namespace and name.
