This page compares the differences between using a Fire TV Stick versus a virtual device for development. For instructions on running apps on either method, visit Run Your App on Vega Virtual Device or Fire TV Stick.

Comparison of test environment

  Fire TV Stick Vega Virtual Device
Hardware Physical device with ARM architecture. Virtual environment using host CPU architecture.
Performance Real-world performance metrics. Limited by host machine capabilities.
Recommended for • Final testing.
• Performance optimization.
• Production validation.
• User experience testing.
• Initial development.
• Quick iterations.
• Basic functionality testing.
• Early debugging.
Supported features All Fire TV components and APIs. Only supports:
In-App Purchasing (IAP)
• Digital Rights Management (DRM) on Mac M-series processors
Webview on Mac M-series processors

Other middleware including Login with Amazon (LWA), Launcher, and other Fire TV APIs are NOT supported.
Performance testing Accurate real-world metrics. Not supported for performance testing.
Development speed For production quality testing. Rapid development and testing.
Testing reliability Good for production environment. May vary from production behavior.

Best practices

  • Perform local and unit testing using Vega Virtual Device.
  • Perform integration and production testing using Physical devices.
  • Use both environments for efficient development and testing.
