NanoID Generator

Generate Multiple NanoIDs

What is NanoID?

NanoID is a tiny, secure, URL-friendly unique string ID generator. It’s similar to UUID v4 but is much more compact while still maintaining excellent uniqueness guarantees. NanoIDs are typically 21 characters long by default (though this is configurable) and use a URL-friendly character set.

Benefits of NanoIDs:

  • Compact: Only 21 characters in default configuration (vs 36 for UUID)
  • URL-safe: Uses URL-friendly characters (A-Za-z0-9_-)
  • Secure: Uses a cryptographically strong random generator
  • Universal: Implemented in over 20 programming languages
  • Customizable: Size and alphabet can be configured for specific needs
