PWA BASICS

Questions about progressive web apps

What is a progressive web app?

A progressive web app is a website that can expose app-like capabilities such as installation, standalone windows, offline behavior, shortcuts and operating-system integrations.

Can every listed PWA be installed?

Installation depends on the app manifest, browser and operating system. PWAs.app shows the signals it can verify and opens the original app for the browser-controlled installation step.

How are PWA scores calculated?

Scores combine HTTPS, manifest validity, app identity, display mode, icons, screenshots and service-worker signals. They are technical health indicators, not editorial rankings.

Does PWAs.app host the listed applications?

No. Every application continues to run on its publisher’s domain. PWAs.app provides discovery, technical reports and optional on-demand Android wrappers.
