From the repository:

Litestack is a Ruby gem that provides both Ruby and Ruby on Rails applications an all-in-one solution for web application data infrastructure. It exploits the power and embeddedness of SQLite to deliver a full-fledged SQL database, a fast cache , a robust job queue, a reliable message broker, a full text search engine and a metrics platform all in a single package.

I’ve been learning Python for my small projects recently, but for something that wants a full stack I’ll definitely be checking this out.
