IntelliJ IDEA vs CodeKit

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.

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.

A very complete development environment support.

IntelliJ supports many languages besides Java, some of these are: golang, Scala, Clojure, Groovy, Bash, etc.

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.

IntelliJ IDEA hardly ever crashes or has any issues that plague other Java IDEs like file corruption or slowness.

IDEA has a clean, intuitive interface with some customization available (such as the Darcula theme).

The documentation is exhaustive, easy to navigate, and clearly worded.

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.

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.

These simplify the daily work, e.g. copy/cut a whole line without the need to select it.

Verify yourselves as a student to get more perks.

Creating an embedded database, running SQL script in a dedicated terminal, viewing tables and their contents, and creating a connection to an in-memory or embedded database is fully supported.

I pay $24 a month and i have access to all jetbrain peoducts , so i use their many tools , i tried many others like netbeans , eclipse , etc , they re good but intelij is on the space and the sky is the limit . Been using it for 5 years and i cant tell i got frustrated using .it

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.

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.

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.

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.

At a one time cost of $29, it's a great deal considering how powerful and easy to use it is.

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.

You can use it to, for example, live-update server-side PHP by establishing a connection with your local MAMP server.

Autoprefixer automagically adds vendor prefixes based on latest information.

CodeKit provides a powerful tool to automatically reduce the size of compressed images and production web code.

CodeKit supports live compilation of Less, Sass, Stylus, Jade, Haml, Slim, CoffeeScript, JavaScript and Compass including automatic debugging and minification.

Install 6,000+ Bower components with a single click: Bootstrap, jQuery, Modernizr, Zurb Foundation, even WordPress.
