What is Sqids?

Sqids (pronounced "squids") is an open-source library that lets you
generate YouTube-looking IDs from numbers. These IDs are short, can
be generated from a custom alphabet and are guaranteed to be
collision-free. Read more .

This is what they look like:

Why use them?

The main use of Sqids is purely visual. If you'd like to use IDs
instead of numbers in your webapp, Sqids could be a good choice:

Use Cases

  * Link shortening Safe to use in URLs
  * Event IDs Collision-free encoding/decoding
  * One-Time Passwords Short & profanity-free

Not Good For

  * Sensitive data This is not an encryption library
  * User IDs Can be decoded, revealing user count

Features

  *  Generate short IDs from non-negative numbers
  *  Easy encoding & decoding
  *  Auto-generated IDs do not contain common profanity
  *  Support for custom IDs through shuffled alphabet
  *  40 programming languages (17 using new design)
  *  Every version produces the same IDs
  *  Small library with a permissive license
