Common use cases

  • Use UUID when you need opaque random 128-bit identifiers in the standard 8-4-4-4-12 hex layout.
  • Use ObjectId when you work with MongoDB-style 24 hex BSON ids—parse embedded seconds or mint local placeholders.
  • Use ULID when sortability by creation time matters—the first characters encode a millisecond timestamp.
  • Use Nano ID when you want short URL-safe strings with adjustable alphabet and length for user-facing tokens.

Common mistakes to avoid

  • Confusing uniqueness with secrecy

    These tools generate identifiers; they are not passwords. Use the password or random-string tools for secrets.

FAQ

Are generated IDs sent to Toolcore?

No. Generation runs in your browser; nothing is stored on our servers.
