Whisk – An Essential Tool for Web Developers

Tumult Inc. releases a new web development product called Whisk. This macOS application is a HTML5 and PHP editor with an integrated preview pane that renders pages live as users type. Whisk joins a family of Tumult’s other best-in-class tools including Hype for producing beautiful animated interactive HTML5 content, and Reflect for previewing web pages on iOS devices.



Whisk’s Live Preview feature empowers rapid development, yet has not been as well utilized in other web editors. Live Preview combines the writing phase with the viewing phase clarifies the effects of users changes, speeding up the overall process of making a web page. Beta testers report frustration returning to prior workflows after using this style of live previewing.


The application contains other features to improve efficiency when editing web pages. W3C-based HTML5 validation will red-underline any mistakes live as users type. Whisk finds files that are used by a document, and automatically reloads the preview when they change on disk. Developer Tools access gives users access to the console and page inspector tools.


“Whisk is the type of app that has a spot in web developer’s dock,” said Jonathan Deutsch, founder and CEO of Tumult. “It is lightweight so it is easy to get in and out of. It doesn’t replace other source editors; Whisk can make whole sites but truly shines when needing to test snippets of web-related code, playing with CSS styling, or writing rich forum or blog posts. Live previewing is a pivotal way to work.”


Tumult Whisk is sold on the Mac App Store and the Tumult Store. For new customers, Tumult Whisk is available for $29.99 USD. Whisk also has upgrade pricing available for existing HyperEdit owners. A fully functional 14-day free trial is available for download.
