Welcome to the Titanium open source project. Titanium provides a mature platform for developers to build completely native cross-platform mobile applications using JavaScript.

Currently supported native platforms are iOS and Android.

Titanium is licensed under the OSI approved Apache Public License (version 2). Please see the LICENSE file for specific details.

Table of Contents


With Titanium, you use JavaScript to code your application. Titanium's compiler will compile your application code into an efficient native executable for each target mobile platform.

  • Native apps built using JavaScript (no hybrid, no embedded WebView)
  • Apps are compiled and run locally with full offline support
  • Support for native platform UI controls (TabGroup (iOS), ActionBar (Android), AppBar (Windows), ...)
  • Support for watchOS targets
  • Support for in-application SQL database
  • Support for Geolocation (compass, geolocation, forward/reverse lookup)
  • Support for Camera (taking Photos, playing and recording Video)
  • Support for Calendar (creating & fetching Events)
  • Support for 3D-Touch (Peek and Pop, Application Shortcuts, ...)
  • Support for Photo Album (reading and writing)
  • Support for Contacts Database / Address Book
  • Support for Streaming Audio and Recording Audio, Audio Input Levels, Mic etc
  • Support for Vibration
  • Support for Social APIs such as Facebook, Twitter, etc.
  • Support for Yahoo YQL
  • Support for Web Services via REST, SOAP
  • Support for native Maps
  • Support for Push Notifications
  • Support for In-Application Email
  • Support for In-Application SMS, Telephone
  • Support for Filesystem (create, read, write, etc.)
  • Support for Gestures (such as Shake and Pinch)
  • Support for Platform and Device capabilities
  • Support for complex native views such as Coverflow, Image Views, Table Views, Grouped Views, Composites, etc.
  • Support for Web Views incorporating HTML5, CSS etc.
  • Completely extensible via Module API and Hyperloop for building your own controls or extending capabilities

And much, much more (see our Documentation for more infos).


Use Hyperloop, our latest addition to the Appcelerator Platform, to extend your Titanium apps by native API's using JavaScript. Prior to Hyperloop, you would use native modules to extend the Titanium API. With Hyperloop, you are now able to implement native classes, 3rd-Party libraries (Cocoapods, local frameworks, .aar files) and more directly into your apps. Hyperloop is available for iOS, Android and Windows Phone (Tech Preview).


Cross-Platform Reuse

Build and maintain apps in a fraction of the time with up to 95% code reuse.

Direct API Access

Access 100% of platform APIs directly, with instant support for each new OS release.

JavaScript Everywhere

Create mobile apps using the world’s most popular programming language.

3rd-Party Libraries

Incorporate 3rd-party native libraries using JavaScript, with no changes required.

Custom Animations

Easily create complex custom effects like dynamic animations using JavaScript.

Run Native

Mobile app development for every major mobile OS – with no hybrid compromises.


Create a native view in iOS and Android:

// iOS
var view = new UIView();

// Android
var view = new View(activity);

Getting Started

Check out our Hyperloop Sample App and Hyperloop Programming Guide to get started with Hyperloop today!


Alloy is the MVC application framework built on top of Titanium. It is optional. It rocks. Check it out if you're considering using Titanium. It is also a separate open source project available under Apache Public License.


Manage your application scope by separating your code into different models, views, controllers and more:

index.xml (View)

  <Window title="Titanium and Alloy">
    <Button onClick="handleClick" id="myButton">Click me!</Button>

index.js (Controller)

function handleClick() {
  alert('Hello from the Controller!');

index.tss (Style)

Window: {
  backgroundColor: 'white'

"#myButton": {
  width: 200,
  height: 30,
  backgroundColor: 'green'

Getting Help

There are a number of ways to get help with Titanium.

Official Documentation, Tutorials and Videos

Please visit the official documentation site at for the latest and historical documentation on Titanium, Alloy and the various products built by Appcelerator.

Slack / Developer Community

Community support and discussion about Titanium is available on Slack at TiSlack.


Please consider following @Appcelerator and @AppcDev on Twitter for updates.

Commercial Support, Licensing

We give our software away for FREE! In order to do that, we have programs for companies that require additional level of assistance through training or commercial support, need special licensing or want additional levels of capabilities. Please visit the Appcelerator Website for more information about Appcelerator or email


Titanium is an open source project. Titanium wouldn't be where it is now without contributions by the community. Please consider forking Titanium to improve, enhance or fix issues. If you feel like the community will benefit from your fork, please open a pull request.

To protect the interests of the Titanium contributors, Appcelerator, customers and end users we require contributors to sign a Contributors License Agreement (CLA) before we pull the changes into the main repository. Our CLA is simple and straightforward - it requires that the contributions you make to any Appcelerator open source project are properly licensed and that you have the legal authority to make those changes. This helps us significantly reduce future legal risk for everyone involved. It is easy, helps everyone, takes only a few minutes, and only needs to be completed once.

You can digitally sign the CLA online. Please indicate your email address in your first pull request so that we can make sure that will locate your CLA. Once you've submitted it, you no longer need to send one for subsequent submissions.

Building Locally

Previously Titanium used scons and python scripts to build the SDK. If you'd like to build the SDK locally, we've replaced scons with some Node.JS scripts. Typical usage would be:

npm ci
npm run cleanbuild

The build and package commands will default to all target platforms on your host OS unless explicitly specified. (i.e. Android, iOS on macOS; Windows and Android on Windows). It will compile, package and install the locally-built SDK for you as well, so you can test it in your own applications without any further procedures.

The build command will look for the Android SDK directory path via the $ANDROID_SDK env variables if not explicitly passed using command line arguments.

You can use the -h flag to display the full list of comands and options.

npm ci
npm run cleanbuild -- [platform1] [platform2] --android-sdk /opt/android-sdk /Users/build/android-sdk-macosx

Unit tests

We have a unit test suite intended to run across all supported platforms.

We have npm scripts set up to run a full clean, build, package, symlinked install, ti sdk select the built sdk, and then run the unit test suite:

npm run test:android
npm run test:iphone
npm run test:ipad

How it works

The test suite generates a single Titanium project targeting the specified platform(s), builds the project for emulator, launches the app on the emulator and then runs a series of tests defined via ti-mocha and should.js.

The tests spit out their results to the console log, and the test scripts listen to the logs to gather the results. We then generate an overview on the console as well as a junit report xml file (to be consume by CI build systems like Jenkins).

How to modify the tests locally and in your PRs

The tests folder contains the test suite. Any files living within that directory are copied on top of the test app's structure.
