Coda from Panic Software offers a sleek, trimmed-down alternative to expensive Web design suites. This one-window Web design app combines all the tools you need to build a site, with an emphasis on creating a fast, easy, integrated workflow.
Coda's collaboration tools let you seamlessly work together with others, and a built-in FTP sidebar--using the power of Panic's powered-up Transmit 4--helps you get your site updated quickly. Hand-coding experts will like the full-featured CSS and text editors (although no code folding here), and editing multiple files side by side in split panes is a breeze. Coda also has tons of time-saving features, including Clips (for frequently used code snippets), an Open Quickly window (for fast access to specific files), and integrated subversion. We particularly like the powerful Find and Replace tools, which let you drag-and-drop global changes to your code.
Coda is neither perfect nor cheap (and we're getting antsy for Coda 2.0), but if you're searching for a reasonably priced Web design tool on the Mac, Coda is a solid choice.
