CodeKit
What CodeKit is
CodeKit is a native macOS application for front-end developers and designers. It watches project folders, compiles source files, optimizes images, and refreshes connected browsers. The app bundles tools for stylesheets, scripts, markup, npm packages, image optimization, browser previews, and build automation. Listed language support includes Sass, Less, Stylus, TypeScript, JavaScript, CoffeeScript, Pug, Haml, Slim, Kit, Markdown, and JSON. CodeKit provides a graphical npm interface and one-click installers for Tailwind CSS, Bootstrap, and Zurb Foundation. Its built-in server refreshes browsers across devices, with TLS and synchronized clicks, scrolling, and form input. A command-line interface lets AI agents compile files, change settings, install packages, run builds, read logs, and open previews. It works with any editor that saves files, with plugins for Nova, Sublime Text, Atom, and Coda. The single-user license costs $39, paid once and includes 13 months of free updates for one user on up to three Macs. A 10-day trial is available.
