Pros
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 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.
