I'm not really qualified for useful feedback, but a while back when I was trying to decide on a truly cross platform development framework, I went with dart/flutter. The reason was, as a noob, I couldn't make any sense of the ridiculous, and ever growing, amount of web focused cross platform frameworks.

With all that said, since you mention flutter, which despite continuing rumours about it's demise, is established and extremely popular; what would make me drop flutter for this?

I'm not being flippant, it's a genuine question.

For me if it's smaller, faster, easily to learn (darts and excellent language, flutter is a lot more complicated), and quicker to write and deploy I'd use it.

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.
