The tool is labeled as a 'preview,' meaning that it's an initial beta with missing features and probably some issues, but it's concrete evidence that Adobe wants to and can support HTML5 along with Flash.
"Edge will be updated regularly to add new functionality, stay ahead of evolving web standards, and incorporate user feedback to provide the best functionality and experience possible," it added.
"This is an early look at Edge with more capabilities to come," it concluded.
The technology for smooth and interesting animations using nothing than standard web stuff is here, but, until now, it required developers to hand write all of the code to handle this.
Adobe Edge is aimed at professionals wanting a more visual approach and should appeal to designers in particular.
The new tool features a familiar timeline in which designers can define the events and stages of the animation.
There is also a live preview of the animation created, courtesy of an embedded WebKit browser engine, to provide real-time feedback.
Animations created with Adobe Edge will work in modern browsers on many devices, but there is still clearly a place for Adobe Flash and the company doesn't plan on replacing the technology with HTML5 or anything else any time soon.
