Titanium SDK

Native iOS and Android apps, written in JavaScript

Titanium runs your JavaScript and TypeScript against real platform APIs, so aButtonis a real button. Not a web view, not a bridge to one.

Install TitaniumAPI reference

Titanium SDK 13.4.1, released

Titanium CLI 9.2.0, released

app.js
// one codebase, two native apps
const win = Ti.UI.createWindow({
  backgroundColor: '#15191c'
});

const button = Ti.UI.createButton({
  title: 'Say hello'
});

button.addEventListener('click', () => {
  alert('Hello from a native button');
});

win.add(button);
win.open();

What Titanium is

Real native UI
Every component maps to the platform’s own widget. A window is an Activity on Android and a UIWindow on iOS, with the scrolling, accessibility and text input that come with them.
JavaScript and TypeScript
Write the language you already know, against a documented API for both platforms. Type definitions ship with the SDK.
Open source, community owned
Apache-2.0, governed by TiDev, a non-profit. Fifteen years old and still shipping - the SDK is developed in the open by the people who use it.

Alloy gives your app a structure

Alloy is Titanium’s MVC framework. Views are XML, styles are a stylesheet, and controllers are plain JavaScript - the same split you would reach for anyway, with data binding and a build step that compiles it all down to the SDK calls above.

Alloy documentation
index.xml
<Alloy>
  <Window>
    <Button onClick="greet">Say hello</Button>
  </Window>
</Alloy>
index.js
function greet() {
  alert('Hello from Alloy');
}

$.index.open();
index.tss
"Window": {
  backgroundColor: '#15191c'
},
"Button": {
  color: '#ffffff'
}

Try it

Install the CLI and Alloy from npm, add the SDK, then scaffold a project and build it. What comes out runs on both platforms without anything else added to it.

Requires Node.js 22.19.0 or newer.

Terminal
npm install --global titanium alloy
ti sdk install
ti create
cd <project-dir>
ti build
