I built this no-code recreation of the Duolingo.com desktop page using Webflow. I re-built all interactions and the start of the first lesson, too. I did this mostly for fun, but also to demonstrate that a high quality SaaS website can be made without writing any code.
I've been learning languages on the Duolingo app since 2012. The way they turn a great task into a light and playful experience is a part of what inspired me to become a designer.
