When comparing IntelliJ IDEA vs CodeKit, the Slant community recommends CodeKit for most people. In the question“What are the best power user tools for macOS?” CodeKit is ranked 20th while IntelliJ IDEA is ranked 52nd. The most important reason people chose CodeKit is:
Everything you need to get a project started is included with CodeKit. Thanks to the professional support, different components of the workflow pipeline are guaranteed to play nicely with each other without you needing to do the research on how to configure them. More advanced features that may require extra configuration to set up with other workflow wrappers are set up out of the box in CodeKit, like automatic browser updating, linting, and source maps.
Ranked in these QuestionsQuestion Ranking
Pro Fast and smart contextual assistance
Uses a fast indexing technique to provide contextual hints (auto-completion, available object members, import suggestions).
On-the-fly code analysis to detect errors and propose refactorization.
Pro Smart refactorings
IDEA places an emphasis in safe refactoring, offering a variety of features to make this possible for a variety of languages.
These features include safe delete, type migration and replacing method code duplicates.
Pro Android support, JavaEE support, etc
A very complete development environment support.
Pro Lots of plugins
Many plugins are available for almost any task a developer may need to cover. Plugins are developed by Jetbrains themselves or by 3rd parties through the SDK available for writing them.
Pro Support for many languages
IntelliJ supports many languages besides Java, some of these are: golang, Scala, Clojure, Groovy, Bash, etc...
Pro Stable and robust
IntelliJ IDEA hardly ever crashes or has any issues that plague other Java IDEs like file corruption or slowness.
Pro Intuitive and slick UI
IDEA has a clean, intuitive interface with some customization available (such as the Darcula theme).
Pro Clear and detailed documentation
The documentation is exhaustive, easy to navigate, and clearly worded.
Pro Free version available
There is a free community edition (open source) and an ultimate edition, which you can compare here.
The ultimate edition is available for free for one year for students but must be registered through an .edu e-mail account.
Pro Very powerful debugger
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 Many convenient features
These simplify the daily work, e.g. copy/cut a whole line without the need to select it.
Pro Everything is set up for you
Everything you need to get a project started is included with CodeKit. Thanks to the professional support, different components of the workflow pipeline are guaranteed to play nicely with each other without you needing to do the research on how to configure them.
More advanced features that may require extra configuration to set up with other workflow wrappers are set up out of the box in CodeKit, like automatic browser updating, linting, and source maps.
Pro Provides a clean and modern GUI
CodeKit has a clean and intuitive graphical user interface out of the box. Most other tools in this category run as command line utilities or require unsupported third-party plugins to run with a GUI.
The CodeKit GUI makes it easier to navigate and manage the various components of your project with helpful UIs like dropdowns, and views that provide extra details without having to run a separate command.
Pro Live browser updating built in
CodeKit has live updating built in and will update monitored files across multiple browsers and devices, and refresh CSS without a new page load. Other workflow wrappers have live updating, but they require extra configuration. With CodeKit, everything is set up for you so you can get it up and running in no time at all.
Pro Interactively define how files compile with a GUI
You can navigate your project directory, and use a menu form to set up how it gets compiled without needing to read configuration documentation, or deal with configuration errors. On top of that, file watching and recompilation is built in with no extra configuration needed.
Pro Great value for money
At a one time cost of $29, it's a great deal considering how powerful and easy to use it is.
Pro Visual package management with Bower
CodeKit provides a clean GUI for Bower that makes it easier to navigate and get information about modules without having to deal with a command line interface.
Pro Connects with MAMP
You can use it to, for example, live-update server-side PHP by establishing a connection with your local MAMP server.
Pro Don't have to worry about vendor prefixes due to Autoprefixer support
Autoprefixer automagically adds vendor prefixes based on latest information.
Pro Reduces size of compressed images
CodeKit provides a powerful tool to automatically reduce the size of compressed images and production web code.
Pro Live pre-processor and script compilation
Pro Has over 6k componenets
Install 6,000+ Bower components with a single click: Bootstrap, jQuery, Modernizr, Zurb Foundation, even WordPress.
Con Built with closed source components
The version with full features is not opensource. Parts of the code are under apache licence though.
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
Con Uses too much RAM
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 Cannot open multiple projects in the same window
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 Mac only
This is a major problem for larger teams that have varied development environments.
You get only the tools that are provided by the application.
