Why SolidTV
SolidTV is unmatched in speed and features
SolidJS is an established framework with 10,000+ members in its community. It is the top rated in performance across all front-end frameworks, and SolidTV brings it to TV app development. SolidTV is:
Fast
Direct template to node creation
Ready
Fully loaded with all the features
Write JSX. Render WebGL.
If your team knows React or SolidJS, they already know SolidTV. Components compile straight to renderer nodes, so there is no virtual DOM and no DOM at all between your code and the GPU.
- ✓ Remote-control focus
and navigation handled by
RowandColumn - ✓ Focus states and transitions declared in a style object
- ✓ Fine-grained updates: only the node that changed is touched
import { For } from 'solid-js';
import { Row } from '@solidtv/solid/primitives';
const posterStyle = {
width: 240,
height: 360,
borderRadius: 16,
scale: 1,
transition: { scale: true },
$focus: { scale: 1.1 },
};
const Rail = (props) => (
<Row gap={24} autofocus>
<For each={props.movies}>
{(movie) => (
<view src={movie.poster} style={posterStyle} />
)}
</For>
</Row>

Supported Platforms
Runs everywhere your viewers watch
The framework performs well on the majority of Smart TVs, set-top-boxes, and really any other device that runs a modern web browser (Chrome 38+). Apple TV has no browser, so SolidTV runs there natively through NativeScript, from the same source code. In terms of TV apps, you should roughly be able to support these types of devices:
Samsung Tizen
LG WebOS
Android TVSony, Philips, Panasonic, TCL
Amazon Fire TV
Apple TVvia NativeScript
Panasonic
Select Set-Top-Boxes
* The one exception is Roku. Its platform only runs apps written in BrightScript, Roku's own language, so no web-based or JavaScript framework can target it.
New · Apple TV
Your TV app on Apple TV, without a Swift rewrite
Apple TV has no browser, which is why web-based TV frameworks stop at its door. SolidTV now runs on tvOS through NativeScript, with no WebView in between. Your app's web entry point is imported unchanged.

FAQ
Frequently asked questions
Which TV platforms does SolidTV support?
SolidTV runs on any device with a modern web browser (Chrome 38+), including Samsung Tizen, LG WebOS, Android TV (Sony, Philips, Panasonic, TCL), Amazon Fire TV, Panasonic, and select set-top-boxes. Apple TV (tvOS) is supported through NativeScript. The one exception is Roku, which only runs apps written in its own BrightScript language.
How does SolidTV run on Apple TV?
Through NativeScript, without a browser or WebView. NativeScript is the
runtime, its canvas plugin provides the WebGL surface, and the
@solidtv/nativescript package connects the
renderer, the Siri Remote and the app lifecycle. Your app's web entry point is imported unchanged.
Read how it works, or follow the
deployment guide.
How does SolidTV compare to LightningJS?
SolidTV delivers roughly 50% higher FPS than LightningJS on equivalent hardware, eliminates layout jitter via Atomic First Paint, and is approximately 12kb minified + gzipped. See the full comparison.
Is SolidTV open source?
Yes. SolidTV is released under the Apache 2.0 license and developed in the open on GitHub. The SolidTV Renderer and the NativeScript host are published on npm under the same license.
Do you offer commercial support for SolidTV?
Yes. Support plans give your team priority answers, a private support channel, priority bug fixes and upgrade guidance. We also offer fixed-scope performance audits, migration assessments, Apple TV ports, custom development and team training. See support & services.
Can you help if our TV app isn't built with SolidTV?
Yes. Performance audits and consulting cover any web-based TV app, including LightningJS, Blits, React and Vue apps running on Tizen, WebOS, Android TV and Fire TV.
Who is behind SolidTV?
SolidTV is created and maintained by Chris Lorenzo, a former Distinguished Engineer on Comcast's Lightning team who has spent years shipping TV apps at scale. More about Chris.
