> The Gomix model is: just click. And in that respect, we have much in common with developer playgrounds like CodePen and JSFiddle. They too are fun for trying things out, and a nice way for developers to share ideas. But they don’t provide any ability to run back-end code, which greatly limits the types of things that you can build with them. What’s more, key features like realtime collaboration between multiple users are often limited to only paying users, putting up a barrier for educational use or simple pair-programming scenarios.
