WEB BROWSER OUTFIT Opera Software has launched its open source web developers' debugging tools.

Only a couple of months after Opera launched the Beta version of its Opera web developers' tools, it has released the 1.0 version of its open source suite of debugging tools for web developers.

Dubbed Dragonfly, Opera's open source suite provides web developers with tools that can tweak Javascript code. It has a Javascript debugger, a DOM and CSS Inspector and works on both the Opera Mobile and desktop versions of the Opera web browser products.

Opera said Dragonfly was designed from the ground up to support new web technologies.

"From the very beginning, we decided to eat our own dog food and develop Opera Dragonfly in web technologies. This was before the HTML5 hype was on every man in suit's lips," wrote Opera Dragonfly blogger David Storey.

Therefore Opera coded Dragonfly in HTML, CSS, Javascript and even SVG, claiming that under the hood it's one of the most complex web applications available.

The tools in Dragonfly are referred to as inspectors. Resource Inspector lets you preview assets used in your web site or application. It can check all types of web site resources including images, scripts, fonts, HTML files and videos.

Network Inspector does the same sort of thing and tracks network latency issues. Storage Inspector manages data collection and lets developers test cookies and monitor network traffic.

Opera also claimed Dragonfly was designed to chew up bugs, hence the name. µ
