I'm writing http://codecaster.io, a tool for teachers to help students in software development classes. Been working on it for over a year and been using it in my classes. I'm looking for other teachers interested in using it so I can get feedback.

I have plans for pricing, but before I can approach that, I need more data on how people will use it.

For technical folks, it uses Phoenix and Elixir, and a lot of JS.
