Progressive web app

A progressive web app is a website built to behave like an installed application: it can be added to the home screen, launched without browser chrome, work offline or on a poor connection, and on most platforms receive push notifications.

Its appeal is distribution. There is one codebase, no app store review, and updates reach users the moment they are deployed — which matters most for internal tools, field applications and any audience that would never deliberately install an app.

It is not a full substitute for a native app. Access to device capabilities is narrower and varies by platform, and iOS in particular has historically supported less of the standard. For a consumer product whose users expect to find it in an app store, the store presence is part of the product.
