A Progressive Web App, or PWA, is a web application built with standard web technologies such as HTML, CSS and JavaScript that can be installed on a device and launched like a native app. The term was coined in 2015 by Google Chrome engineer Alex Russell and designer Frances Berriman.

PWAs rely on a service worker, a script the browser runs separately from the page to enable offline use and push notifications, and on a web app manifest that defines installation details such as the app's name and icon. They can be distributed through a web address without going through an app store.
