A Progressive Web App (PWA) is a web app that provides an app-like user experience. PWAs are built with progressive enhancement as the core tenet, which means they work for every user, regardless of browser choice because they’re built on modern web standards. This means that PWA’s work seamlessly on any device and don’t require a native installation to provide an app-like experience.

PWAs load like regular websites but they have some of the features of a mobile app: they’re fast, lightweight and provide push notifications. They also load from cache when possible so people can use them even if there’s no internet connection available.
