Microsoft Edge is a proprietary cross-platform web browser created by Microsoft and based on the Chromium open-source project, superseding Edge Legacy. In Windows 11, Edge is the only browser available from Microsoft. However, a bypass is available to open Internet Explorer.

First made available only for Android and iOS in 2017, in late 2018, Microsoft announced it would completely rebuild Edge as a Chromium-based browser with Blink and V8 engines, which allowed the browser to be ported from Windows 10 to macOS. The new Edge was publicly released in January 2020, and on Xbox as well as Linux in 2021. Edge was also available on Windows 7 and 8/8.1 until early 2023.
