Why should I use nanoid instead of UUID?

Nanoid is 40% shorter (21 vs 36 chars), 2x faster, URL-safe without encoding, and has equivalent collision resistance. UUID still wins for enterprise systems that mandate RFC 9562 compliance.

Can I generate IDs with only numbers for order codes?

Yes. Set alphabet to '0123456789' and size to 8 for an 8-digit numeric order code like '47829163'. Works with any character set you define.

Is it safe to use as a secret token or API key?

Yes. Nanoid uses crypto.getRandomValues() — the same cryptographic PRNG used for TLS keys and encryption. Increase the size to 32+ characters for high-security tokens.

UUIDs are 36 characters. That's 36 characters in every URL, every database row, every API response, every log line. Nanoid gives you the same collision resistance in just 21 characters — URL-safe, no encoding needed, and cryptographically secure.

With 40M+ weekly downloads, nanoid is the ID generator behind Supabase, Vite, and PostCSS. This MCP lets any agent generate production-grade IDs without hallucinating random strings.

The Superpowers

21 Characters = Same Security as UUID: The math proves it — ~1 billion years to have a 1% collision probability at 1,000 IDs/hour.
URL-Safe by Default: A-Za-z0-9_- — no percent-encoding, no base64 headaches.
Custom Alphabet: Need numeric-only IDs for order numbers? Hex-only for tokens? Pass any character set.
Cryptographic: Uses crypto.getRandomValues() — the same API used for encryption keys.
