Panic Coda is a shareware web development application for the Mac OS X operating system. It seeks to reduce the amount of applications (such as an FTP client, CSS editor, a version control system, etc.) you need to develop websites and to improve your team’s workflow. Coda’s one-window web development philosophy uses a tabbed interface for text editing, file transfers, SVN, CSS, and even "Books" which embeds web books that are searchable (it comes with The Web Programmer’s Desk Reference but you can add your own).
