Projects we've worked on

Bundler manages an application's dependencies across many machines systematically and repeatably.


Handlebars provides the power necessary to let you build semantic templates effectively with no frustration.


Thor is a simple and efficient tool for building self-documenting command line utilities, as well as an alternative to Rake.
