https://www.nitrous.io/ IDE in a browser, it really works. Extremely fast setup, start coding in a few minutes. Some limits to which packages can be installed in your environment. These are pay services, but they all offer a free level. Internet connection required, which may raise some security questions. Free service is not private, which may raise some security questions. Easy to install github repos and deploy to heroku or other services. Least amount of control over your development environment. Slightly better arrangement for browser testing than loading pages locally.
