Builder is an open source, multi-language, build automation tool with transparent logs and metadata tied to each build. It's the only build tool that allows you to pass in a repo and build your project, while getting extensive metadata tied to your shippable product. There's no need to frantically track down build info if something goes wrong. Know who built it, in what directory, on what machine, at what time. Our motto, "Never not know again," encapsulates this ethos perfectly.
