Appcelerator announced a preview of Appcelerator Titanium, an open-source platform for building desktop and mobile applications using a common set of Web technologies. The technology enables developers to build desktop Web applications that can operate both online and offline. That capability prompts comparisons with Adobe AIR, but Appcelerator boasts open-source components as opposed to Adobe's proprietary technology.
Appcelerator has announced the release of a public preview of Appcelerator
Titanium, an open-source platform for building desktop and mobile applications
using a common set of Web technologies.
Appcelerator officials said Titanium enables developers to use standard Web
technologies such as HTML, CSS and
multiple platforms, including the desktop, the browser or the mobile device.
This capability has caused more than one observer to view Titanium as a clear
competitor to Adobe Systems' Adobe Integrated Runtime (AIR).
"[It] is easiest if you think of [Appcelerator] as an open Web version
of Adobe AIR in that it is a run-time that
has extended APIs that allows developers to create applications using Web
technology," said Dion Almaer, co-founder of Ajaxian.com.
As with Adobe AIR, Titanium, unlike
traditional Web applications, which are limited to operating within the browser,
enables developers to create applications that are able to read and write local
data on the desktop and interact with the operating system. In particular,
Titanium enables developers to build desktop Web applications that can operate
both online and offline.
Titanium is built on top of a number of leading open-source technologies,
including WebKit, Gears and Chromium, and is designed to work on Windows, Mac
and Linux desktop operating systems. The Windows and Mac versions are available
immediately, and the Linux version will be available in January 2009. Titanium
is distributed under the Apache Public License.
"It is built gluing and molding WebKit, Chromium and Gears in very
interesting ways indeed," Almaer said of Appcelerator. "A lot of
tough work was done in getting the glue to bind to graphics tool kits on
various platforms, and then the work to tear apart Gears and allow it to take
in new modules which implement APIs such as native windowing [transparent
custom chrome], direct file system access, database integration and storage,
desktop notifications, application and system menu control, and geo-location."
"Developing for the desktop had shifted down in priority in recent
years," said Michael Cote, an industry analyst with RedMonk. "But
desktop development has recently picked up more interest as rich Internet
application [RIA] technologies have pulled down the Web development experience
to the desktop. Increasingly, developers have the option to use known Web
frameworks to expand into a previously unreachable area, the desktop."
Although Cote said it is too early to tell whether Titanium
is a "game changer," it is definitely a technology to watch,
particularly for the enterprise.
"In the RIA world, Adobe is currently king simply because they've been
at it so long and control the tool set," Cote said.
"That said, they lack being fully open source when it comes to [the newly
named] Flash Platform. This may not have been a problem for their existing,
Flash-centric developer base, but as Adobe expands out into the 'enterprise'
and traditional developer world, it's becoming a problem.
"For Appcelerator, then, the fact that Titanium is open source is very
interesting. I think in 2009, the 'game changing' moves for all the RIA and AJAX
use, not so much the raw technology itself."
