EdgeHTML is a proprietary layout engine developed by Microsoft for the Microsoft Edge web browser. It is a fork of Trident that has removed all legacy code of older versions of Internet Explorer and rewritten the majority of its source code with web standards and interoperability with other modern browsers in mind. The rendering engine was first released as an experimental option in Internet Explorer 11 as part of the Windows 10 Technical Preview build 9879.
EdgeHTML is designed as a software component to allow software developers to easily add web browsing functionality to their own applications. It presents a COM interface for accessing and editing web pages in any COM-supported environment, like C++ and .NET. For instance, a web browser control can be added to a C++ program and EdgeHTML can then be used to access the page currently displayed in the web browser and retrieve element values. Events from the web browser control can also be captured. It is also used to render WinRT-apps that are based on web technologies.

Microsoft first introduced the EdgeHTML render engine as part of Internet Explorer 11 in the Windows Technical Preview build 9879 on November 12, 2014. Microsoft planned to use EdgeHTML both in Internet Explorer and Project Spartan, in Internet Explorer it would exist alongside the Trident 7 engine from Internet Explorer 11, the latter being used for compatibility purposes. However, Microsoft decided to ship Internet Explorer 11 in Windows 10 as it was in Windows 8.1, leaving EdgeHTML only for the new Edge browser. EdgeHTML was also added to Windows 10 Mobile and the second Windows Server 2016 Technical Preview. It was officially released on July 29, 2015 as part of Windows 10.
