easy to use its like make project start & code one minus is that you have 512 ram which is kinda bad for java things also Code envy is easy to use and its very easy to deploy it on cloud. Some times the working code isnt debugged I don't know the problem maybe its just me the IDE is like linux terminal feels the same some commands are blocked codenvy has Multiple programming languages and a great website theme. I definitely recommend codenvy. codenvy has powerful servers so no need to be scared if your project doesnt run
