With ability to step into a certain part of a large method invocation (Shift+F7), drop frame, executing code snippets, showing method return values, etc.
Pro Easy setup
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.
Pro On-demand, instant-access, real-time collaborative IDEs
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.
Pro Has a fully functional free tier
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.
Pro Powerful editor
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.
It allows going to any box and pick up a project and work on it.
Pro Fantastic Java support
All Java builders, syntax highlighting, class navigator, jump to package and declaration, and JavaDoc are present in Codenvy.
Pro Can provide a custom runtime environment
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.
Pro Git support
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.
Pro Provides a terminal with root access
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.
Pro Partly open source
Codenvy is a full multi-user, multi-account, multi-tenant implementation of Eclipse Che.
Pro Complete build lifecycle
The IDE allows validating, compiling, testing, packaging and deploying.
Pro Badge to start developing in one click
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.
Pro Integrates with a wide variety of tools
Codenvy offers first class support for code management, continuous integration, PaaS, and project management tools.
Pro Self-hostable (priced)
Codenvy has an on-premises solution that allows running it on own hardware and behind a firewall. The service costs $300/user/year.
Pro Automation of contribution to GitHub projects
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.
- fork of the origin project on github
- add ssh keys to push to github
- create pull request in the origin project
- create factory url for review of this pull
- post this factory in pull request.
Then project's owner can use posted link to code review/run project with changes.
Pro Lots of built-in templates
Pro Nice interface
Look and usability of Codenvy IDE are nice and pleasant.
Pro Can be used for Android development
Can be used for android development by adding Eclipse plugin.
Pro Easy projects sharing
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.
Pro Custom build system support
Codenvy allows setting up any build system via Dockerfile. Instructions on how to do it can be found here.
Pro Has Eclipse plugin
Codenvy can be plugged into Eclipse offering choice between online and offline builds. Plugin can be found here.
Pro Developer workspace replicas
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.
Pro Quick support from staff
Pro One-click automation
Pro SSH Access
Can connect to the workspace via SSH for use with desktop editors.
Pro Provides Java debugger
Pro Includes Subversion support
Codenvy includes full subversion version control support.
Pro Portable workspaces
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.
Pro Install anywhere Docker runs
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:
Con Bugs are not solved as often as they should
They are more interested in adding new features or issuing new versions than solving bugs.
Con Slow startup
Startup can be slow deepending on system configuration
Con Built with closed source components
The version with full features is not opensource. Parts of the code are under apache licence though.
Con Cannot open multiple projects in the same window
Con Uses too much RAM
Con Standard hotkeys behave differently
Seems like hotkeys assignment in Idea has no logical consistency.
Like «F3» is usually next match, «Ctrl+W» - close tab, etc — they map to some different action by default.
There is a good effort in making the IDE friendly for immigrants from other products: there are options to use hotkeys from Eclipse, and even emacs. But these mappings are very incomplete. And help pages do not take this remapping into account, rather mentioning the standard hotkeys.
So, people coming from other IDEs/editors are doomed to using mouse and context menus (which are rather big and complex).
Con Lack of plugins
IntelliJ supports a very small amount of plugins. Althrough thesse are 'quality approved', many features are missing and can't be implemented because of that.
Con No SSH, FTP mode
For example, "Code everywhere" allows using SSH, FTP as base of project. In Codenvy it's possible only through VM.
Con No custom keyboard shortcuts
No possibility to create custom keyboard shortcuts.
Con Lacks two-factor authentication
Con Non-optimistic UI, typing results in letters being sent to server and back and then they show.
Con No IE support
Does not support Internet Explorer and no official plans have been publicly announced for its addition.
Con Slow installation by default
Trying to install with "npm install" and the server restarts before the installation. However, you can circumvent this by using
npm install --no-bin-links.
