GLITCH

Glitch is a simple but powerful tool for creating websites and full-stack apps, supported by a fun and friendly community of creators—from brand new coders to expert developers. Glitch’s editor is like Google Docs for coding. The code editor lets multiple people work in the same project at the same time. And there's no messy install or set-up process: Go to Glitch.com, start a new project, and everything you create publishes to the web automatically (and every change updates just as soon as you make it). And it's supported by a community of creators who have created more than 2.5 million apps, all ready to remix and customize. Glitch was founded as Fog Creek Software, the company behind Trello and Stack Overflow, by Joel Spolsky and Michael Pryor. Anil Dash is its CEO.
