Honestly, the biggest difference is how they treat the web. Flutter brings its own entire rendering engine to the browser to draw pixels on a canvas, while Coi is designed to use the browser's native HTML and CSS.

If you’ve used Vue or React, Coi will feel much more familiar. It’s a component-based model where your logic, styles, and markup live together, but you get strict static typing and native-speed performance via WASM.

The goal is a true "write once, run everywhere" workflow. On the web, it stays light by using the browser's engine. For mobile and desktop, the plan is to map that same HTML/CSS styling and component logic to a native C++/Skia backend. You get a native app's performance without losing the web's layout flexibility.
