What is Amazon Luna?
Luna is a cloud gaming service that lets you play games on compatible Fire TV, Windows PC, and Mac devices as well as through web apps on iPhones and iPads. Cloud gaming enables you to play games on devices you already own, without the need to purchase a gaming console or gaming PC. Games live in the cloud, so there are no lengthy downloads, installs, or updates required.
You need a high-speed internet connection, compatible game controller or mouse and keyboard, and supported Windows PC, Mac, Fire TV, iPhone, and iPad.
You can play with the Luna Controller, Xbox One controller, DualShock 4 controller, or use a mouse and keyboard. Luna Controller supports Bluetooth and USB for offline play on many devices. Luna Controller is not licensed for play on game consoles. Luna supports both 2.4 GHz and 5 GHz. Amazon recommend 5 GHz for an improved gaming experience. The minimum recommended internet connection speed for streaming games is 10 Mbps (35 Mbps required to play in 4K). Better internet connections will result in improved streaming quality and resolution.
You can use the Luna app on: PC (requires Windows 10 with support for DirectX 11) Mac (OSX 10.13+) FireTV devices (Fire TV Stick Lite, Fire TV Stick - 2nd and 3rd generation, Fire TV Stick 4K, Fire TV Cube, Toshiba Fire TV Edition, Insignia Fire TV Edition) Chrome web browser (version 83+) for PC (Windows 10) and Mac (OSX 10.13+) Safari web browser (iOS14) for iPhone and iPad

Said about Amazon Luna as an alternative
Basically the same thing with less "oomph" so to speak.
