Progressive web app

A progressive web application (PWA), or progressive web app, is a type of web app that can be installed on a device as a standalone application. PWAs are installed using the offline cache of the device's web browser.

PWAs were introduced from 2016 as an alternative to native (device-specific) applications, with the advantage that they do not require separate bundling or distribution for different platforms. They can be used on a range of different systems, including desktop and mobile devices. Packaging and publishing a PWA, as an installable app, to digital distribution systems, such as the Apple App Store, Google Play, or the Microsoft Store on Windows, can optionally be performed.

Because a PWA is delivered in the form of a webpage or website built using common web technologies including HTML, CSS, JavaScript, and WebAssembly, it can work on any platform with a PWA-compatible browser. As of 2025, PWA features are supported to varying degrees by Google Chrome, Apple Safari, Brave, Firefox for Android, Microsoft Edge,, Vivaldi and Firefox for Windows.
