Debug Ext JS and Sencha Touch apps directly at the source

Sencha Inspector is a debugging tool that provides direct access to components, classes, objects, etc. for apps built using Sencha frameworks. Inspector is designed to provide application insights and intelligent debugging capabilities for any Sencha application developed with Ext JS 4.2.0, 5.x, 6.x or Touch 2.1.0 and above – regardless of the browser you’re using. It lets you analyze your application code for issues, such as overnesting of components, number of layout runs, and helps improve your application performance.

Inspector even lets you theme your Sencha applications by providing access to modify any Ext JS and Sencha Touch Sass variables. Because Inspector comes pre-integrated with Sencha Cmd, all theme changes can be viewed in near real-time.

With Inspector, you can also debug Sencha applications running on your mobile devices (including iOS and Android) using the remote debugging capabilities of the tool.

Inspector is available as part of Ext JS Premium package. Try Sencha Inspector for a free 30-day trial by downloading Ext JS trial. The confirmation email includes a link for Inspector, so you can just select it if you’ve already downloaded Ext JS.

Inspector supports the following browsers: Chrome, Firefox, IE 10+, and Safari 6+.
