Nano ID is a tiny (118 bytes), dependency-free JavaScript library for generating secure, URL-friendly unique string IDs using a hardware random generator. It packs a similar number of random bits to UUID v4 into just 21 characters using a larger alphabet, and is faster than crypto.randomUUID().

Use cases

• generate unique ids for database records
• uuid alternative for javascript
• generate short url-friendly identifiers
• generate random ids in react components
• secure random string generator for node
• generate ids for pouchdb or couchdb documents

When to choose

• you need short, URL-safe unique IDs smaller than UUIDs
• bundle size matters and you want a zero-dependency library
• you need faster ID generation than crypto.randomUUID or uuid v4
• you want customizable alphabet or ID length

When to avoid

• you need sequential or sortable IDs like ULID or snowflake IDs
• you need standardized UUID format for interoperability
• you need cryptographically verifiable or non-random IDs
