Titanium makes cross-platform native application development easy.
A free and open source application development platform, Titanium let’s you create native mobile and desktop application experiences using existing web skills like Javascript, HTML, CSS, Python, Ruby, and PHP.

Titanium For Mobile:
Titanium translates your hard won web skills into native applications that perform and look just like they were written in Objective-C [iPhone] or Java [Android]. With over 300 APIs, a thriving developer community6, and the support you need, you can build applications that are more social, local, media rich, interactive, and extensible.

Titanium For Desktop:
Build more engaging applications that have better performance and full control over OS-specific UI, database access, offline functionality, notifications, and multimedia. Flaunt your geek cred with Linux applications, go mainstream with Windows, get hip with OSX, or do all three from one code base. Titanium apps take up to 1/10th the memory of Adobe AIR apps and have complete access to the local system.
