Superpowers, the collaborative HTML5 2D+3D game maker, is now open source

Superpowers at its core (http://github.com/superpowers/superpowers) is more than a game maker. It's a generic collaborative client/server Web app for building all kinds of projects. A project type is defined by what we call a system, and you can have any number of systems installed on your Superpowers server.
We spent most of the last year building the core along with a system called Superpowers Game (https://github.com/superpowers/superpowers-game), which is a TypeScript game engine built on top of Three.js along with a bunch of collaborative asset editors.
Now that the platform is maturing, we've started work on other systems. For instance, Superpowers LÖVE (https://github.com/superpowers/superpowers-love2d) lets you build Lua games for the LÖVE framework. Demo: https://i.imgur.com/yLybycP.jpg
Another example: Superpowers Web is (https://github.com/superpowers/superpowers-web) a Superpowers system for building static Websites. We've used it to build the official website (https://github.com/superpowers/superpowers-html5.com) in real-time collaboration. We have plan for a "Superpowers Node.js" system, and hopefully the community will embrace this extensibility and build cool tools for all sorts of engines and creative endeavours.
You can find lots of pictures of the app in the release notes: https://github.com/superpowers/superpowers/releases and many games made with Superpowers Game here: http://sparklinlabs.itch.io/. The devlog album has cool stuff too: http://imgur.com/a/NdIuH
