Smart TV emulator: which tool for which TV

“Smart TV” is not one operating system. A Samsung set runs Tizen and an LG set runs webOS. Other sets and streaming boxes run Android TV or Google TV, Roku OS, Fire OS or tvOS. So the first question is not which emulator to use, but which TVs your app ships to.

This page lists the official tool for each platform, what it needs, where it stops, and how to get onto a physical set. Every vendor claim links to the vendor’s own documentation, checked October 29, 2026. If you only want to watch TV on a computer, none of this applies: these tools are for building and testing apps.

Which tool for which TV

TV	Official tool	Main limit
Samsung (Tizen)	Tizen Studio TV emulator	Slower than a TV; no UHD or voice
LG (webOS)	webOS TV Simulator	Web apps only; no DRM
Android TV, Google TV	Android Studio emulator	Wants 16 GB of RAM
Apple TV	Xcode tvOS Simulator	Needs an Apple silicon Mac
Roku	Roku Cloud Emulator	Early pilot; US-only
Fire TV	Virtual Fire TV devices; Vega Virtual Device	Vega device lacks Fire TV middleware

Every tool here except Amazon’s virtual Fire TV devices and the Roku Cloud Emulator runs on one computer. A teammate or a coding agent somewhere else cannot use it.

VibeView also runs three of these TVs in a browser: Apple TV and Android TV as cloud simulators, and Roku on physical hardware. Fire OS apps run on its Android TV devices. See Apple TV, Android TV and Roku in a browser.

Samsung Tizen: the TV emulator in Tizen Studio

What it is and what it needs. Samsung’s TV emulator is a virtual machine built on QEMU, with a virtual remote. Samsung’s TV SDK also includes a TV Simulator, according to its install guide. You install Tizen Studio, then the TV Extensions from its Package Manager. You start the emulator from Emulator Manager. Samsung’s prerequisites ask for Intel VT-x on Windows and macOS, or VT-x or AMD-V on Linux. The emulator cannot run inside Remote Desktop, VirtualBox, VMware or Parallels. The macOS line names “Intel-based hardware” and does not mention Apple silicon.

Where it stops. The emulator page says “The emulator is slower than a real TV.” The limitations page lists no camera, no gesture or voice control, no 3D and no long-press. Bluetooth, UHD resolution and secure WebSockets are missing too, and “Apps Search” does not work.

On a physical TV. Samsung’s Remote Test Lab has a TV section for Tizen apps. It lists a QLED 4K TV.

LG webOS: the webOS TV Simulator

What it is and what it needs. LG’s webOS TV Simulator imitates a webOS TV on your computer. It has a remote, an inspector for debugging, and auto-reload when you save. LG’s installation page lists versions for webOS TV 6.0 and webOS TV 22 to 26. They run on 64-bit Windows 7 or later, Ubuntu, or macOS 10.13 or later. On a Mac, the webOS TV 25 and 26 simulators are Apple silicon builds only.

Where it stops. Only web apps run: “Native apps are not supported (only web apps are supported).” The simulator “does not support DRM function”. Its “video and audio specifications are different from actual TV devices”, and some Luna and webOSSystem APIs are missing. LG’s older VirtualBox-based webOS TV Emulator is deprecated: “From webOS TV 22, Emulator will not be provided.”

On a physical TV. LG’s Developer Mode app lets you install test apps on your own webOS TV, signed in with an LG Developer account. LG says “Developer Mode enables for a limited time”, so you extend the session as you go.

Android TV and Google TV: the Android Studio emulator

What it is and what it needs. The Android Emulator “comes with Android Studio”. Google recommends at least 16 GB of RAM on 64-bit Windows 10 or later, macOS 12 or later, Linux or ChromeOS. When you create a virtual device, the device types include both Android TV and Google TV. Google’s TV guide says to run the app on a virtual TV device for testing.

Where it stops. On a machine below that spec, Google says the emulator “might still run but not smoothly”, and suggests testing on a physical device instead.

On a physical TV. The same TV guide covers running the app on a TV device with USB debugging turned on. For d-pad and focus checks, see test Android TV d-pad navigation.

Apple TV: the tvOS Simulator in Xcode

What it is and what it needs. Apple TV apps run in the tvOS Simulator that comes with Xcode. Apple’s Xcode support page lists tvOS simulators (tvOS 17 or later) for current Xcode. Xcode is free. Its App Store listing says it “Requires macOS 26.6 or later and a Mac with Apple M1 chip or later.”

Where it stops. That requirement is the main limit: current Xcode needs a Mac with Apple silicon. A developer on Windows or Linux has no official way to open an Apple TV simulator. Neither does a tester or a client without a Mac.

On a physical TV. The same support page lists device support for Apple TVs on tvOS 17 or later, run from Xcode on that Mac. For the no-Mac route, see building an Apple TV app without a Mac.

Roku: the Roku Cloud Emulator

What it is and what it needs. The Roku Cloud Emulator gives you virtual Roku players and TVs on Roku’s servers, which you open from a browser. Roku says it is “currently being deployed to developer accounts as part of a phased rollout.” Roku’s FAQ, posted September 14, 2026, calls it “early pilot access, not general availability”. After 5 free hours it costs $0.20 per hour, according to that post.

Where it stops. Instances are US-based only, and subscriptions are for users in the USA. Roku says the virtual devices are “not intended for real-world platform, speed, and performance testing”. There is no HDMI, no voice and no suspend and resume, and the only remote is the built-in web one. Protected video plays at HD only, through Widevine L3. Its API guide covers key presses, other ECP commands, sideloading and the debug consoles. It documents no screenshot call.

On a physical TV. A retail Roku in developer mode accepts a sideloaded channel. For every Roku route, including open-source BrightScript simulators, see Roku emulator options.

Amazon Fire TV: Fire OS and Vega OS

What it is and what it needs. Fire TV has two operating systems. Amazon describes Fire OS as “a fork of Android”. On its Fire OS overview, Fire OS 7 is based on Android 9 and Fire OS 8 on Android 10 and 11. The newer Fire OS 14 and 16 are based on Android 12 to 16. For Fire OS apps, Amazon offers cloud-hosted virtual Fire TV devices in Appstore Quality Central, opened from your Amazon Developer Console. For Vega OS apps, Amazon’s Vega Virtual Device runs on your own computer for early development.

Where it stops. For the virtual Fire TV devices, Amazon asks for a connection over 100 Mbps. A device left idle for more than 15 minutes can disconnect. On the Vega Virtual Device, Amazon says “Login with Amazon (LWA), Launcher, and other Fire TV middleware are NOT supported.”

On a physical TV. Test on a Fire TV device before release. For Vega OS, Amazon’s advice is to “Perform integration and production testing using Fire TV device.”

Other TV platforms

Vizio, Hisense VIDAA, game consoles and operator set-top boxes each have their own developer programs. This page does not cover them. If one of them is on your list, start from that vendor’s developer site.

Apple TV, Android TV and Roku in a browser

VibeView streams three TV platforms to your browser. You pick a device on the Devices page:

• Apple TV: tvOS simulators, so you can run and test the app without a Mac. See the Apple TV simulator page.
• Android TV: Android TV emulators, with your arrow keys as the d-pad. See the Android TV emulator page.
• Roku: physical Roku hardware, streamed live, with your channel sideloaded for the session. See Roku app testing.

On all three you can invite a teammate into a live session, send a share link, or embed the app on your own site. Tests work the same way on each. Record a test once and replay it, or run AI tests (beta), and run your groups from CI.

A coding agent can drive the TV through the CLI or the MCP server (vibeview agent-setup sets it up). It reads what is on screen and which element has focus. It can move focus to an element and select it, press remote buttons, type, take screenshots and read app logs.

The same account that runs these TVs also runs iOS and Android phones and tablets. The Free plan includes streaming minutes each month.

What VibeView does not run, or runs only in part:

• No Samsung Tizen and no LG webOS. Use Samsung’s emulator and Remote Test Lab, and LG’s simulator.
• Fire OS apps run as Android TV apps; Vega OS apps don’t. A Fire OS .apk uploads and runs on an Android TV emulator. The device reports itself as Android TV, and Amazon services such as in-app purchasing and Login with Amazon are not available. See Fire TV (Fire OS) apps.
• Apple TV runs as a simulator and Android TV as an emulator. Check hardware-specific behavior on a physical set before release.
• Roku sessions use physical devices. When all of them are in use, a new session queues until one is free.

Pick by the TVs you ship to

• Samsung TVs: Samsung’s Tizen TV emulator, then Remote Test Lab for a physical set.
• LG TVs: LG’s webOS TV Simulator for web apps, then a TV in Developer Mode.
• Android TV or Google TV, on your own computer: the Android Studio emulator.
• Apple TV, with no Mac for you or your testers: VibeView.
• Roku, without one on your desk: VibeView streams a physical Roku. See Roku emulator options for the rest.
• Roku, with Cloud Emulator access and your own test scripts: the Roku Cloud Emulator.
• Fire OS apps: VibeView’s Android TV devices for everyday testing, Amazon’s virtual Fire TV devices for Amazon services, then a Fire TV stick.
• Vega OS apps: the Vega Virtual Device, then a Fire TV device.
• Apple TV, Android TV and Roku together, shared with a team or a coding agent: VibeView.

Before a release, work through the smart TV app testing checklist on whichever devices you choose.

Frequently asked questions

Is there one emulator for all smart TVs? No. Each TV operating system has its own tool. A Tizen app needs Samsung’s emulator and a webOS app needs LG’s simulator. The one overlap is Fire OS: its apps are Android apps, so they also run on an Android TV emulator, without Amazon’s services.

Is there a smart TV emulator online? A few run in the cloud instead of on your computer. The Roku Cloud Emulator and Amazon’s virtual Fire TV devices both open in a browser. VibeView streams Apple TV, Android TV and Roku devices to a browser on any operating system.

What is the difference between a TV emulator and a TV simulator? The names are loose. Apple calls its tool the tvOS Simulator, and LG calls its current tool the webOS TV Simulator. Samsung offers both a TV Simulator and a TV emulator, while Google and Roku say emulator. What matters is what each tool runs and what it leaves out, listed above.

Can I run a Samsung TV emulator on a Mac? Samsung’s prerequisites list macOS on Intel-based hardware and require Intel VT-x. They do not mention Apple silicon. Check Samsung’s current Tizen Studio downloads before you plan around an Apple silicon Mac.

Can I test an Apple TV app without a Mac? Not with Apple’s tools, because current Xcode needs a Mac with Apple silicon. VibeView runs tvOS simulators in the browser, so you can run and test an Apple TV app from Windows or Linux.

Does VibeView run Samsung, LG or Fire TV apps? Not Samsung, LG or Vega OS apps. Fire OS apps run on the Android TV devices, without Amazon’s services, alongside Apple TV, Android TV and Roku apps. For Tizen and webOS, use the vendors’ tools listed on this page.
