Edge is a proprietary, cross-platform {{Glossary("Browser","web browser")}} developed by Microsoft in 2014. Initially known as "Spartan", Edge replaced {{glossary("Microsoft Internet Explorer", "Internet Explorer")}}, which had been Microsoft's primary browser for over 20 years.
Edge is included with Windows 10 and Windows 11, and is also available for macOS, iOS/iPadOS, Android and Linux.
Edge used EdgeHTML as its {{Glossary("Engine/Rendering", "rendering engine")}} until 2019, when it was replaced by {{glossary("Blink")}}, the rendering engine used by {{Glossary("Google Chrome")}}. On iOS/iPadOS, Edge uses {{glossary("WebKit")}} as its rendering engine. Edge supports 'IE mode' for backwards compatibility that uses the {{glossary("Trident")}} engine to render pages requiring legacy Internet Explorer features.
