Meteor / Node.js Application Hosting Service running on Digital Ocean

You can learn more about the service on the home page - http://stackful.io. There's a short video introduction that might be helpful.

What is that demo app you deploy on the video?

The placeholder app that comes with the stack is TodoMVC [1] and the one used to demonstrate git deploy setup after that is Telescope [2].

Do you support websockets?

(Stackful.io developer here)

Yes, thanks to the websocket support that landed in recent Nginx releases.
