Allows web apps (as defined by the Web App Manifest standard) to set an app-wide badge in operating-system-specific places such as the shelf or home screen. Additionally, it gives the app a small, visible place to notify the user of new activity that might require attention, without showing a full notification. It can show additional information, such as an unread count or event type. It allows the app to convey this information when its windows are closed.

Shipped on Windows and macOS. Chrome OS support coming in (likely) 91. Android and Linux support are unlikely as those platforms don't have a native badge API.
