Three platforms, three technology stacks
Samsung Tizen and LG webOS apps are web applications, built with HTML, CSS and JavaScript and packaged for each store. Android TV and Google TV apps are native Android, written in Kotlin with Jetpack Compose for TV or Leanback. They share goals but not code. Tizen and webOS dominate in some countries and Android TV and Google TV in others, while Roku and Fire TV matter elsewhere, so market data should guide the launch order instead of a default list.
Framework choice affects reuse. A React or Lit based web client can serve Tizen, webOS and sometimes other browsers with platform adapters, while Android TV usually remains its own build. We decide where to share by looking at your catalog, DRM needs and team. Web engine age is the main hazard. Some televisions ship with browsers several years behind desktop Chrome, so we transpile, avoid unsupported CSS, polyfill carefully and run the app on the oldest model you agree to support.
