NanoID Sync Generator

Synchronous URL-safe unique string ID

Generating...

About

NanoID's synchronous version generates IDs immediately without async operations. It's smaller than UUID and uses a larger alphabet to achieve the same level of randomness in a shorter string. The synchronous API is perfect for client-side generation, server-side rendering, and any context where you need immediate ID generation without promises or callbacks. It's the default and most commonly used NanoID API.

Use Cases

  • •Client-side ID generation in React/Vue/Angular
  • •Server-side rendering (SSR) applications
  • •Synchronous code paths
  • •Real-time ID generation without async overhead
  • •Browser-based applications
  • •Immediate ID requirements

How to Generate
