Web Development
What is a Progressive Web App (PWA)?
Quick answer
A Progressive Web App is a website built to behave like a mobile app — it loads fast, works offline, and can be installed on a phone's home screen — without needing the App Store or Play Store. It runs in the browser but feels native.
PWAs use modern browser features (service workers, a web app manifest, HTTPS) to cache content, send push notifications, and launch full-screen like an installed app. For many businesses they deliver 80% of what a native app offers at a fraction of the cost, because there is a single codebase and no app-store review.
They're a strong fit when you want app-like convenience — offline access, home-screen icon, push — but your users would hesitate to download a full app. E-commerce stores, booking tools, and content sites benefit most.
