PWA (Progressive Web App)
A PWA (Progressive Web App) is a website built with modern web tech that can be installed to a home screen, work offline, and send push notifications — delivering an app-like experience without an app store download.
In plain English
A PWA is a website wearing an app costume. Visitors can 'install' it with one tap, use it offline, and get notifications — but you didn't have to build and ship separate iOS and Android apps.
How it works
- 1A service worker caches assets so the app loads fast and works offline.
- 2A web app manifest lets users install it to their home screen.
- 3HTTPS and responsive design make it secure and usable on any device.
- 4Optional push notifications and background sync add native-like features.
Instead of installing a heavy app, a user taps 'Add to Home Screen' on a store's site and gets an icon that opens instantly, works on the metro with no signal, and pings them about orders.
Why it matters
A PWA is a great fit when you want app-like reach without app-store friction, need offline access, or want one codebase serving web and 'app'. For deep device features, a native app may still win.
