Progressive web apps explained
Definition: a progressive web app (PWA) is a website that behaves like an app — it can be installed to the home screen, work offline, and send notifications — without going through an app store.

Building a mobile presence doesn't always mean building a native app. For many businesses, a progressive web app delivers most of the app experience at a fraction of the cost. Here's what a PWA is and when it's the right call.

What makes an app "progressive"

A PWA is built with standard web technology but adds app-like capabilities: users can install it to their home screen, it loads fast and can work offline, and it can send push notifications. It runs in the browser, so there's one codebase and no app-store approval to manage.

Why businesses choose PWAs

When a native app is still better

PWAs have limits: they can't access every device feature a native app can, and some users still expect to find you in the app store. If you need deep hardware integration, maximum performance, or a strong app-store presence, native (or cross-platform native) may suit better. For content, commerce and most everyday apps, a PWA is often the smart, cost-effective choice.

A PWA gives you most of an app's benefits without most of an app's cost.
Key takeaways
  • A PWA is a website with app-like powers: install, offline, notifications.
  • One codebase, no app store, lower cost, instant updates.
  • Native still wins for deep hardware needs or app-store presence.

Frequently asked questions

Can a PWA work offline?

Yes — that's one of its defining features. With the right setup, a PWA can load and function without a connection, then sync when it's back online.

Do PWAs appear in app stores?

They can be listed in some stores, but they're primarily installed straight from the web. If app-store presence is important to you, factor that in.

Is a PWA cheaper than a native app?

Usually yes — one web codebase serves all devices, avoiding the cost of building and maintaining separate native apps.
