Opera's open source web debugger enters beta

Opera Software has announced the release of an official beta for its open source Dragonfly tools for web authoring and debugging. Similar to Mozilla's integrated web development tool for Firefox, Firebug, Opera Dragonfly is a fully featured debugging environment for Opera's Presto-based browsers that allows developers to debug JavaScript and inspect the DOM, CSS, network traffic and data stores.

According to the company, the Dragonfly beta adds a number of refinements aimed at making developers' "life in front of the screen just a little easier". Opera Dragonfly 1.0 beta features a new breakpoints panel that allows developers to 'slice and dice' (debug) their JavaScript with static or conditional breakpoints. The developers have also added new ways to inspect network loads, resource handling and cookies.

The company also introduced a new beta for version 11.10 of its Opera web browser, code named "Barracuda", and new versions of Opera Mini and Opera Mobile at this year's South by Southwest (SXSW) event.

More details about the first beta of Opera Dragonfly can be found in the company's official press release and on the project's home page. Opera's developer pages provide an introduction to Dragonfly, as well as the details of the program architecture. Opera Dragonfly source code is hosted on Bitbucket and released under an Apache 2.0 license.
