What is Sqids?
Sqids (pronounced "squids") is an open-source library that lets you generate short unique identifiers from numbers. These IDs are URL-safe, can encode several numbers, and do not contain common profanity words. Read more .
This is what they look like:

Quick encode & decode example:
var sqids = Sqids.new()
var id = sqids.encode([1, 2, 3]) # "86Rf07"
var numbers = sqids.decode(id) # [1, 2, 3]If IDs are too short, you can pad them to a certain length:
var sqids = Sqids.new({
min_length = 10,
})
var id = sqids.encode([1, 2, 3]) # "86Rf07xd4z"
var numbers = sqids.decode(id) # [1, 2, 3]Create unique IDs by shuffling the alphabet:
var sqids = Sqids.new({
alphabet = "k3G7QAe51FCsPW92uEOyq4Bg6Sp8YzVTmnU0liwDdHXLajZrfxNhobJIRcMvKt",
})
var id = sqids.encode([1, 2, 3]) # "XRKUdQ"
var numbers = sqids.decode(id) # [1, 2, 3]Full documentation is at https://github.com/sqids/sqids-gdscript
Use Cases
The main use of Sqids is purely visual. If you'd like to use IDs instead of numbers in your project, Sqids could be a good choice.
Good For
- Encoding primary keys If you're using a relational database
- Saving database lookups By encoding multiple objects
- Temporary login tokens Profanity-free and URL-safe
Not Good For
- Sensitive data This is not an encryption library
- User IDs Can reveal user count if anyone finds out the encoding alphabet
