Roku OS
Streaming isn’t just one thing we do—it’s all we do. We built the Roku operating system (OS) specifically for streaming TV with one goal in mind—getting you to the entertainment you love quickly and conveniently. The Roku home screen puts you in control with the entertainment you love front and center. You’re always just a click away from your favorite channels, useful features like search, and quick access to quality free entertainment with Featured Free. Everything about the Roku OS is designed with ease in mind. That means smooth setup, a simple home screen anyone can use, your favorite entertainment at your fingertips, and automatic updates with new features so your device gets even better over time. With endless free entertainment available to stream, the Roku OS helps your dollars go further. It’s easy to save with 250,000+ free movies and TV episodes, 150+ live channels on The Roku Channel, and search results ranked by price.

Apple tvOS
Your tvOS apps can deliver amazing experiences with stunning picture quality through 4K resolution, Dolby Vision, and HDR10 — and immersive sound through Dolby Atmos. And with Picture in Picture, multiuser, and game controller support, you can create even more engaging gaming and interactive experiences. We’ve reimagined the TV experience with tvOS — an innovative TV platform that redefines what can be done in the living room. Apple TV features a built-in App Store, making it more entertaining than ever. Now you can deliver incredible and immersive apps and games on the big screen. Leverage many of the same frameworks, technologies, and concepts that are similar to iOS. Frameworks and technologies, such as Metal, UIKit, CloudKit, and Game Center, let you create rich games and apps that look amazing on Apple TV. TVMLKit templates using XML and JavaScript are available as a framework for tvOS apps and let you use predefined layouts and JavaScript APIs to quickly create beautiful apps.

Fire OS
Fire OS is the operating system that runs Amazon's Fire TV and tablets. Fire OS is a fork of Android, so if your app runs on Android, it will most likely run on Amazon's Fire devices too. You can quickly check your app's compatibility with Amazon through the App Testing Service. As a developer, you might not have to adjust your Android code at all to publish your app on Amazon's platform. Most Fire devices receive over-the-air updates to get Fire OS updates automatically. Not every Fire device receives a push of the same Fire OS version at the same time. The updates often roll out to different devices at different times. At the core, both Fire OS and Android share the same foundation. The main way Fire OS differs from Android is in the services. Instead of using Google's services (for activities such as browsing, location, messaging, payments, and so on), Fire OS might use Amazon's services.
