F.lux vs CodeKit

Helps provide better sleep for more energy during the day.

Decreases color temperature at night, changing the normally fluorescent blue of an LCD monitor to a soft orange. Much easier on the eyes, especially in a low-light environment.

The transition from daytime to nighttime color modes takes an hour by default and will detect your current timezone, meaning that it will happen in the background at sunset, often without you noticing.

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.
