For context, we're teaching an 8-week introduction to programming course, and our students are business professionals who don't have a technical background and don't plan on becoming full-time programmers. The most important consideration for us is a user-friendly setup where the important components (terminal/CLI, text editor, a 1-click button for starting up a server, etc.) are all in one place. This way students don't have to spend time installing anything on their computers, and instructors don't have to worry about students using Mac vs Windows. Since Amazon recently fully integrated Cloud9 into their AWS service, the interface has become quite unfriendly for students just starting out. There no longer even seems to be an option to create a new workspace with a particular template. Considering that we're teaching Ruby on Rails, the option of generating a barebones app with GUI interface was very appealing. I've seen some alternatives out there but haven't tried them yet: - Koding https://www.koding.com/ - Replit https://repl.it/ - Plunker https://plnkr.co/ - Visual Studio Code https://code.visualstudio.com/ with LiveShare https://code.visualstudio.com/bl... I'd love to know if there's a good alternative that comes close to the old version of Cloud9?
