The new, experimental Web Install API is now in Origin Trial in Microsoft Edge and Chrome. The API allows developers to programmatically trigger a PWA installation prompt from in-app user interactions. The API aims to simplify software discovery and distribution, particularly for users who are unaware of the install icon in the browser’s address bar or do not typically use app stores.
