We've been intrigued by Glitch, which is a collaborative online development environment that lets you easily copy and adapt (or "remix") existing web apps or create your own. Rooted in the "tinkerer" ethos, it's ideal for people learning to code but it has the capability to support more complex applications. The main focus is on JavaScript and Node.js, but it also has limited support for other languages. With integrated live editing, hosting, sharing and automatic source versioning, Glitch offers a refreshing and distinctive take on collaborative programming.
