About SitePen Labs

We believe the health of the web and the opportunities available result from the open and collaborative nature. Our team makes significant investments in research and development of open source web tools and technologies.

We leverage open-source technologies for our web applications, and we have the advantage of employing a number of the founders and developers of those projects, which include DWR, Cometd, and the Dojo Toolkit. These projects form the foundation for thousands of web applications and are used by many of the world's most successful companies. Using open-source technologies shortens development time and lets us focus on inventing new features instead of reinventing the wheel. Our experience with these technologies allows us to get the best performance for your applications, resulting in lower overall server costs, larger communities, and better scalability for increased demand for your application.
