Today appMobi added to its lineup of free and open source HTML5 development tools with the immediate availability of debugMobi, a free remote JavaScript debugging tool.

Until now, HTML and JavaScript have been difficult for developers to debug on mobile devices because of the closed environments of smartphone hardware and Web browser software. An open source tool called “Web Inspector Remote” (WEINRE) provides remote Web debugging for mobile devices, but it requires developers to configure and run their own servers in order to work.

debugMobi dramatically reduces the complexity of remote debugging on mobile devices with a configuration-free, hosted version of WEINRE that developers and mobile devices can tap into from anywhere on the Internet. Like all appMobi cloud services, debugMobi is hosted on the global Amazon AWS “cloud,” which offers dependable high performance all over the world.

debugMobi provides Web developers with a remote window into the target mobile device while the hybrid app or site is actually running. JavaScript and CSS variables can be examined, and JavaScript code can be viewed and modified on the desktop viewer in real time. Because debugMobi is hosted on the open Internet (as opposed to the more typical WiFi or Intranet hosting), debugMobi can be used to debug devices that are physically anywhere in the world – making it the first truly worldwide “remote” debugging tool for mobile HTML5.

This new HTML5 developer tool can be used by anyone who is developing Web-based code for mobile devices, including Web app developers, and hybrid app developers using appMobi or PhoneGap. debugMobi is available immediately at www.debugmobi.com. For developers who use the Google Chrome browser, it is also available as a  Chrome extension.
