Pseudocephalopod is a simple slug library for ActiveRecord 3.0 plus, built partly out of annoyance with existing solutions and partly because I wanted something lightweight but with several non-standard features.

It’s main features are:

1. A very simple and tested codebase
2. Support for slug history (e.g. if a users slug changes, it will record the old slug)
3. Simple defaulting for slugs to UUID’s (to avoid showing ID’s.)
4. Built on ActiveRecord 3.0
5. If stringex is installed, uses stringex’s transliteration stuff

More importantly, it is incredible simple to add to existing rails 3 applications.
