Nodester is an open source platform that provides free Node.js hosting. It currently hosts around 2,000 apps and is built on Amazon EC2 instances. The main components are proxy.js which handles all HTTP and Websocket requests, and app.js which handles the REST API, CLI, and nodester.com site. The roadmap includes separating out features, reorganizing the system layout, looking at alternative sandboxing, and potentially breaking components out to their own VMs.
