The core component of Titanium is the Apache-licensed software development kit, Titanium SDK. Appcelerator also makes Alloy, an Apache-licensed, Titanium-based model–view–controller framework, and Titanium Studio, now Appcelerator Studio a proprietary integrated development environment starting at $36/month per seat.
The core features of Appcelerator Titanium include:
- A cross-platform API for accessing native UI components such as navigation bars, menus, and dialog boxes and native device functionality including the file system, network, geolocation, accelerometer, and maps.
- Transparent access to native functionality not already covered by the API.
Some developers have reported that although working with Titanium gives fast results, making Titanium well suited for prototyping, there are issues around differences in behaviour of the API cross-platform, stability and memory management, that made them re-write their apps in native code in the end.
When it was introduced in December 2008, Titanium was intended for developing cross-platform desktop applications and was sometimes compared to Adobe Air. However, it added support for developing iPhone and Android mobile applications in June 2009, and in 2012, Titanium Desktop was spun off into a separate, community-driven project named TideSDK. Support for developing iPad-based tablet apps was added in April 2010. BlackBerry support was announced on June 2010, and has been in beta since April 2013. Tizen support was also added in April 2013 with the 3.1.0 Titanium Studio and SDK releases.
In April 2010, Appcelerator expanded the Titanium product line with the Titanium Tablet SDK. The Titanium Tablet SDK draws heavily from the existing support for iPhone, but it also includes native support for iPad-only user interface controls such as split views and popovers. Initially the mobile SDK only supported development for iPad, but support now includes Android-based tablets as well.
In June 2011, Appcelerator released Studio and Titanium Mobile 1.7. Titanium Studio is a full open standards IDE that is derived from Aptana Studio which Appcelerator acquired in January 2011.
