Whisk is a lightweight HTML and PHP editor with a live preview that updates as you type.

*** Whisk’s free download includes 14-day fully functional trial and document viewer mode. An In-App Purchases is available to unlock the full edition, with discounts for previous owners. ***

Whisk is an essential app in your toolkit for HTML, PHP, CSS, and Javascript programming. It is great for learning web development, testing snippets of code, or building entire web pages.

Whisk’s integrated preview pane displays the web page live as you type. Whisk 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.


Whisk is the app previously known as HyperEdit! For a comprehensive list of what’s new, visit:

Love the instantly-updating preview!

I am really enjoying using Whisk for writing little snippets of CSS and JavaScript! Since this app's preview refreshes INSTANTLY with every keystroke, you see your work come to life in real time... it saves a surprising amount of time as you work on getting your CSS effect just right. No more saving and switching to your browser to refresh.

It's a well-built app, and love the native Mac feel! Kudos to this developer!

Shockingly light on preferences

What should be a groundbreaking light weight tool is hobbled by a lack of basic customizations. For example, there's no control of word wrap indentation, or of word wrap itself. Other common preferences, such as auto save, custom keyboard shortcuts, are nowhere to be found. Perhaps this is on purpose, but it sure does slow down the workflow of many developers. It's a shame, everything else about Whisk seems on point.
