Generated locally in your browser with the Web Crypto API. Nano IDs use A-Z, a-z, 0-9, underscore, and hyphen. Multiple Nano IDs can copy as lines, CSV, or a JSON array.

Compact URL-safe identifiers

Generate Nano ID-style strings for mock API payloads, database seed data, URLs, and UI prototypes without sending anything to a server.

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