I'm looking for full-blown web IDE solutions, with the following features:
1) Polyglot: Support for multiple programming languages and preferably web frameworks (using project templates, base container images, etc.), build and test tools
2) Embedded Shell: CLI shell to interact with the execution environment
Some options I'm aware of include:
1) Eclipse Che on OpenShift (https://che.openshift.io)
2) Repl.it (https://repl.it) - This isn't a full-blown IDE though
