Eclipse Che is a browser based IDE that allows anyone to contribute to a project without installing software. Che defines a new type of workspace that is composed of projects and runtimes, making its state distributable, portable and versionable. We use VMs, containers, and Web services to bring repeatability, consistency, and performance to workspaces.
SpecsUpdate
Pros
Pro GIT and SVN VCS support
Projects can be easily imported from any Git or Svn repository hosting service.
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.
