I got it. I thought you were using some kind of proxy or something. But it's completely client side I guess. That's nice.
You can try Tauri/Electron to build a cross platform app. The app will be a browser instance that renders the website and can remove ads, cookies and other headers easily & legally as technically it's not a website.
Btw. Don't you have GitHub or X?
