Radi is an HTML5 authoring application that has been in development since 2010, but only recently has it begun to feel like a true contender.
HTML5 is gradually and stealthily taking over from a number of existing standards and formats online. The easiest of these to identify is Flash - an observation made more credible by the fact that Adobe is phasing out support for the format on mobile platforms while developing new HTML5 authoring tools. Radi’s main competition is one such tool - Adobe Edge.
Trying them side by side, Edge is clearly the more polished application - with a UI familiar to CS users and slick, interactive tutorials built in. But you’d be unwise to dismiss Radi because of this. Radi may seem similar to Edge - but it’s a more powerful proposition altogether.
Sure, it shares many similar features. The vector drawing and animation capabilities, for example. There are scripting features that enable you to build interaction and a timeline based interface to create animation. Look deeper and Radi has a different approach under the hood. While Edge (and Tumult Hype, the application’s other clear rival) enable you to create animation using CSS and the HTML5 DOM, Radi’s unique selling point is that it harnesses the <canvas> feature of HTML.
This opens the doors to much more sophisticated results, including real-time filters, 3D and video features. All are missing from Radi’s competitors. We’re also impressed by Radi’s programming interface, which borrows from video effects stablemate Conduit.
The program is currently free in beta. If you’re serious about the next phase of web and mobile development, check it out.
