Ranked in these QuestionsQuestion Ranking
Greenfoot is free to use.
Pro Great for beginners
Greenfoot was developed as a way to teach Java to first time programmers.
Greenfoot provides for variety of additional resources such as tutorials and community support.
Pro Docker runtimes
Pro Custom commands
I like that I can package up custom commands with my workspace and then use them (or share them) with everyone else.
Pro SSH + terminal
Built-in terminal with root access so I can make changes to my running machines. Although I don't use it often being able to SSH into the workspace so I can use a desktop IDE is handy.
Pro Portable workspaces
The workspace in Che includes project sources, IDE and the runtime. So if you hand your Che workspace definition to another user and they execute it they will get everything they need to build, run and debug the project.
Also the runtime is in a Docker container so it will work even if the second user is on a different OS than the original user who shared their workspace with them.
Che does a nice job to automatically map the service:port running in my Docker container (e.g. tomcat on 8080) to the Docker port it actually uses (something in the ephemeral range). I never need to figure that out - it's just made available to me when I run my server.
Pro GIT and SVN VCS support
Projects can be easily imported from any Git or Svn repository hosting service.
Pro Reproducible environment
Pro Merge tool for VCS
Pro Open Source
Con Not ideal for professional programmers
Greenfoot is developed to teach programming through creating basic graphical applications (such as simple games).
Though it features an IDE, the interface is quite simple and isn't likely to meet the needs of most experienced developers.
