Codenvy is a full multi-user, multi-account, multi-tenant implementation of [Eclipse Che](https://github.com/eclipse/che/_ which is open source but only single-user/account/tenant. Codenvy open source projects can be viewed on GitHub.

It allows going to any box and pick up a project and work on it.

One of the few good options out there for those who want to write and test applications in the cloud. Easy to setup, and easy to use. The interface is clean and works well on larger or smaller screens. It is easy to get an application up and running in no time.

Look and usability of Codenvy IDE are nice and pleasant.

Codenvy has a fast, secure browser-based editor that supports syntax highlighting, code completion, refactoring and more. It can be used to edit, build, run and debug projects. It even has multi-cursor support.

The layout will be familiar to most developer, especially those experienced with Eclipse, with a file explorer on the left, code on the right and tabs for builders, runners, terminal and events at the bottom.

Once an account is set up and the user has logged in, all that's needed to start is to pick a language, a framework and a PaaS. Codenvy also allows anonymous logins albeit with some important limitations.

Codenvy can provide a runtime environment to test and debug code. This can also be used to share work progress with a client.

Codenvy uses Docker as the runtime application and gives access to Dockerfiles allowing any environment that runs on Linux to be built. This allows using any database, reverse proxy or builder, etc. Codenvy even provides SSH access to running container in every image.

There's also a selection of pre-built environments to speed up the development.

The IDE allows validating, compiling, testing, packaging and deploying. Application modules & APIs can be created and published.

Codenvy provides a fully functional free tier with 4 GB of RAM and unlimited workspaces, free and public projects and developers. Premium subscription start at $1/month and offers machines with up to 200GB of RAM. Codenvy also offers an on-premises solution that costs $300/user/year.

Codenvy allows setting up any build system via Dockerfile. Instructions on how to do it can be found here.

Codenvy can be plugged into Eclipse offering choice between online and offline builds. Plugin can be found here.

Can be used for android development by adding Eclipse plugin.

Codenvy has an on-premises solution that allows running it on own hardware and behind a firewall. The service costs $300/user/year.

You can install Codenvy on any OS that has Docker running on it. The simple install syntax can work through proxies and even offline.

You can use this for proxy install:

You can use this for offline install:

Codenvy offers a terminal with full root access into the machine. Since machines can be defined with Dockerfiles this gives the ability to create any custom environment for building, running or debuging and all the access that's needed to use it as a local machine.

Codenvy supports all Git commands through UI and Codenvy CLI.

Codenvy also integrates well with all major Git hosting providers including GitHub, BitBucket, GitLab. Sign up, sign in, repo cloning, uploading SSH keys are supported. Tutorials for integrating various providers can be found here.

Codenvy offers first class support for code management, continuous integration, PaaS, and project management tools.

Codenvy includes full subversion version control support.

Codenvy provides contribution button that can be placed in Readme.md file on GitHub. It automates contribution to the Github's projects. User clicks this button and it opens a ready to run/edit version of the project in Codenvy. If a user makes changes, Codenvy takes care of everything needed for the contribution on GitHub.

1. fork of the origin project on github
2. add ssh keys to push to github
3. commit
4. push
5. create pull request in the origin project
6. create factory url for review of this pull
7. post this factory in pull request.

Then project's owner can use posted link to code review/run project with changes.

Projects are share by sharing the link (public projects), adding access rights (private and public projects) and factory.

Factory allows to share projects along with build/run settings. To try run/review project recipient just need an URL. Factory also works with external git repositories so it allows share github/bitbucket/other git hosting projects. Recipient doesn't have to be registered. It also allows giving out a share button that activates the factory and counts how many times it is used.

Codenvy "Factory" feature enables developers to create temporary IDE workspaces with full code, build, test, deploy, and collaboration functionality that can be shared with a URL. Multiple people can work in the same workspace making code reviews and teaching simpler and faster. And there's no limit to collaborators.

Factories also work with external git repositories and can be shared with not registered users of Codenvy. It also allows counting how much a factory is used.

Codenvy can create a recipe for a developer workspace that includes the build and run environment configuration plus all the IDE plug-ins, syntax rules, policies and other items. Then version and store that with the code in a repository. Makes it impossible to get a code change that doesn't build and run.

Can connect to the workspace via SSH for use with desktop editors.

You can send someone a short JSON file and your whole workspace (projects, config and runtime) can be replicated for them in a separate container. Great for coordinating among team members.

You can create a .codenvy.json containing the Factory configuration which includes what binaries to install and how to set up the IDE, may be even start the development server. Then create a badge and put it on your GitHub repository and people can start coding and may be compile and run your server with one click.
