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.

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.

Support does sometimes does not read requests thoroughly, and offers ham-baked or non-workable sulutions.

This is a major problem for larger teams that have varied development environments.
