app layout

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. Publishing the app to digital distribution systems, such as the Apple App Store, Google Play, or the Microsoft Store on Windows, is optional.
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, and Firefox for Windows.
