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:

Super snappy instantly-updating preview

Great to see this app fully updated for Apple Silicon and Big Sur – running great on my M1 MacBook Air!

Still loving this app for working on small snippets of HTML, CSS, and JavaScript. Since this app's preview refreshes INSTANTLY with every keystroke, it saves a surprising amount of time as you work on getting your CSS just right and feels refreshingly lightweight.

Looks good at first glance

It is not free, to anyone getting their hopes up. It's 30 bucks after two weeks you get to see if you like it. Had about half a day using it so far, I've been looking at different text editors since my UltraEdit trial ran out and I don't feel like paying the $100 to keep it, this one is my favorite so far. Probably will make a purchase if it continues working like it is and change my rating once I get to settled. So far I'm very happy so thanks to the developers I hope you keep up the good work

Just Right!

For a guy like me who writes occasional HTML but not often enough to not have to play with it, this beats starting Apatche and then dragging modified files to the Apatche documents folder in the Library and then haerd refresh of a web browser, by a mile!
