Tumult Whisk is the lightweight HTML and PHP editor with a live preview pane that displays the updated page as you type. It is an essential app for your web dev toolkit.
Tumult Whisk’s integrated live preview breaks the tedious cycle of writing HTML, saving the file, then reloading and viewing the page in the browser. Combining the writing phase with the viewing phase clarifies the effects of your changes and speeds up the overall process of making a web page. W3C-based validation will red-underline any mistakes. It uses the same rendering engine found in Safari, so it is not only standards compliant, but also very fast.
