Progressive Web Applications are apps that are intended to be used both in-browser and on mobile devices. They load like regular web pages but can offer user functionality such as working offline, push notifications, and device hardware access traditionally available only to native applications.

PWAs combine the flexibility of the web with the experience of a native application, and they are most probably the future of web development. PWA are developed using the most popular front-end frameworks such as Angular, React, and Vue.js, which offer built-in solutions for developing PWAs.

The Progressive Web Applications have a few key features that define them and make them differ from other types of apps. These features are supported by all newer browsers. There is an in-browser tool that helps examine the PWA readiness of an app called Lighthouse. It audits the app on different parameters and shows the results.
