Internet Explorer released Developer Channel, a fully functioning browser designed to give web developers a sneak peak at the web platform features we’re working on. Developer Channel can run alongside and independently of IE11 and is available for developers using Windows 8.1 and Windows 7. It has all of the features from IE11 plus some new ones: support for WebDriver, support for the Gamepad API, updates to WebGL and enhancements to the F12 Developer Tools.
More enhancements to the F12 Developer Tools
In April, we described some of the new capabilities of F12 Developer Tools in IE11 with Windows 8.1 Update, and its focus on providing accurate data in the DOM Explorer and actionable data in the memory and performance tools. IE Developer Channel comes with even more improvements to the F12 developer tools, including:
- An enhanced debugging experience with event breakpoints that help you get to your event-driven bugs faster.
- Richer analysis capabilities throughout the Memory and UI Responsiveness profilers, which support further reduction of noise through multi-dimensional timeline filter, while further increasing the semantic value of the data being reported by lighting up performance.measure() based instrumentation and dominator folding.
- An improved navigation experience that provides more keyboard shortcuts (ctrl+[ and ctrl + ]), as well as newheader notifications, which allows you to quickly determine whether any of the profiling tools are running or how many errors your page has.
A complete set of enhancements is available on MSDN here.

Automate your tests with WebDriver
IE Developer Channel also comes with support for the emerging WebDriver standard through which web developers can write tests to automate web browsers to test their sites. It’s a programmable remote control for developing complex user scenarios and running them in an automated fashion in your web site and browser. See how you can setup WebDriver in the IE Developer Channel, and try out this sample WebDriver project.

IE Developer Channel also improves WebGL performance and adds support for instancing extension, 16-bit textures, GLSL builtin variables, and triangle fans. This release improves our Khronos WebGL Conformance Test 1.0.0 score from 93% to 97%. For more info about these WebGL APIs, go to MSDN here.
The first of many Developer Channel releases
As we work on new features and standards, we will continue to share early code through the IE Developer Channel. You can always go to the DevChannel.Modern.IE page to learn more about the latest features in the IE Developer Channel. All of the new features supported in IE Developer Channel are also listed on Status.Modern.IE, our new portal to communicate our roadmap for interoperable web platform features.
This release of the IE Developer Channel uses a combination of code changes and App-V Client to virtualize and run alongside IE11.
