Both Fire TV and Android TV run Android under the hood, which means both can run web2tv. But the experience differs in a few practical ways that are worth knowing before you pick a box — or decide which TV in the house gets the app.
Fire TV
Fire TVs and Sticks are everywhere, cheap, and easy to sideload using the Downloader app. The new 4K Max sticks are genuinely fast for browsing. The catch: Fire OS puts more aggressive limits on background apps, and some sites detect the platform and serve mobile layouts more aggressively — web2tv's desktop-layout fixes handle that automatically.
Android TV
Android TV boxes (from brands like Nvidia, Xiaomi and Sony TVs) give you full Android with ADB sideloading, often more storage and RAM, and cleaner remotes for apps designed for TV. Browsing feels slightly more "native", and keepers of the ecosystem for years have been using a browser for ages — just not a good one. Until now.
