The success of Ruby has always been dependent on high quality open source libraries. The best known example is of course Rails. The codebase at Redbubble is mainly a monolithic Rails application with very few independent modules. While looking at possible architectures to move forward (which is outside the scope of this article) we also decided to start open-sourcing some of the code, small and large, that make our site run. We’re happy to present our first couple of open-sourced gems, KeyVault and ConditionalCapistrano.
