Tech Dictionary Term

What is a Progressive Web App (PWA)?

Official Definition

A Progressive Web App (PWA) is a type of application software delivered through the web, built using common web technologies including HTML, CSS, and JavaScript. It is designed to work on any platform that uses a standards-compliant browser, offering an app-like experience (including offline use, push notifications, and home screen installation) directly from a URL.

Why It Matters

Getting users to search the App Store, download a 100MB file, and grant permissions is incredibly difficult. PWAs eliminate this friction completely. Users visit your website link, click 'Add to Home Screen', and instantly get an offline-capable, highly responsive application that takes up less than 1MB, bypasses app store fees, and runs smoothly on all devices.

Key Advantages

Zero App Store FrictionUsers install the app instantly from their web browser with one tap.

Offline CapabilityService workers cache key data, letting the app load without an internet connection.

Push NotificationsRe-engage users on their mobile devices directly through web notifications.

Unmatched PerformanceLightweight structure ensures incredibly fast page loads and smooth scrolling.
