Open Source. Free. Agile Project Management. We code and design for a living. We’re crazy about Agile; it makes us better at our jobs and our customers love it. We believe in Open Source because we are part of a global community that thrives on sharing creativity and skill. We love our work. And we want to be happy doing it. But the Project Management Tools that are out there weren't making us happy. In fact we hated the whole lot of them. Bloated, slow, ugly to look at and unintuitive, we just couldn't stand the sight of them a moment longer. So we banished them from browsers and built our own dream tool.
