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:

To encode & decode:
config = Sqids.configure()
id = Sqids.encode(config, [1, 2, 3]) # "86Rf07"
numbers = Sqids.decode(config, id) # [1, 2, 3]
Randomize IDs by providing a custom alphabet:
config = Sqids.configure(alphabet="FxnXM1kBN6cuhsAvjW3Co7l2RePyY8DwaU04Tzt9fHQrqSVKdpimLGIJOgb5ZE")
id = Sqids.encode(config, [1, 2, 3]) # "B4aajs"
numbers = Sqids.decode(config, id) # [1, 2, 3]
Enforce a minimum length for IDs:
config = Sqids.configure(minLength=10)
id = Sqids.encode(config, [1, 2, 3]) # "86Rf07xd4z"
numbers = Sqids.decode(config, id) # [1, 2, 3]

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:
