Random CUID2 Generator

Length

CUID2 count

1-50 CUID2s

Copy format

Generated locally in your browser with the Web Crypto API. These are format-shaped CUID2 fixtures — lowercase base36 (0-9, a-z) always starting with a letter — not the hash-derived output of the real @paralleldrive/cuid2 library. Multiple CUID2s can copy as lines, CSV, or a JSON array.

Collision-resistant identifiers for fixtures

CUID2 is the default ID format in stacks like Prisma and many TypeScript and Node apps. Generate CUID2-style strings for mock API payloads, database seed data, and UI prototypes without sending anything to a server.

Create one CUID2 or a batch of up to 50 for fixture data, import files, and seeded test records.
