It remains a website at its core: users can reach it on the web, and it may be installable, work offline, send notifications, or integrate with device features depending on how it is built and where it runs.
What is a progressive web app?
MDN Web Docs defines a progressive web app as “an app that’s built using web platform technologies, but that provides a user experience like that of a platform-specific app.” In practical terms, a PWA starts with a web experience and can add app-like presentation and capabilities where the browser supports them.

“Progressive” refers to progressive enhancement: the site should remain usable as a website, while browsers that support additional capabilities can offer more. Someone whose browser cannot install the app can still visit and use its web version.

PWA is not a guarantee that every app has every app-like feature. Capabilities vary with the implementation and the browser and operating system being used.

- Be installed: Where supported, a browser can offer an install option so the app can be launched in an app-like way.
- Work offline or with a weak connection: An implementation may use a service worker to manage network requests and provide selected offline behavior. The PWA label alone does not mean all pages or features work without a connection.
- Run background tasks or send notifications: These functions may be available where the app and platform support them.
- Integrate with device features: A PWA may access supported device capabilities, but feature availability is not universal or necessarily equivalent to a native app.
- Reach users through the web or an app store: The web is a distribution channel; a store listing is optional.
What does it take to be installable?
Installability depends on the browser. A web app manifest is a JSON file that describes the app to the browser, including identifying information and how it should appear and behave. MDN says a web app needs a manifest with enough information for the browser to install it. Browsers also apply their own technical criteria, so there is no single install prompt or timeless checklist that applies everywhere.
A service worker is commonly used to provide offline behavior, but it is not required for installation. Having one also does not, by itself, establish that the app works offline: the developer must implement and support the behavior the app needs.

How is a PWA different from a website or native app?
| Aspect | Conventional website | Progressive web app | Platform-specific app |
| How people reach it | Through the web. | Through the web; installation may be available in supported browsers. | Developed for a particular operating system or device platform. |
| Installation | Not an inherent website feature. | Possible where the browser supports installation and the app meets its criteria. | Distributed as an app for its target platform. |
| Offline and background behavior | Depends on the site’s implementation. | May be implemented with web platform features; neither offline use nor background functions are automatic. | Depends on the app and platform. |
| Device integration | Depends on browser capabilities and implementation. | May use device capabilities exposed by the browser and operating system. | Built for its target platform’s capabilities. |
| Distribution | Web. | Web, with app-store distribution also possible but optional. | Platform-specific distribution. |
This is a distinction in approach, not a promise of feature parity: a PWA can feel app-like, but its capabilities should be judged for the particular app and platform.
Is a PWA the same as a single-page app?
No. “PWA” describes an app’s use of progressive enhancement and web platform capabilities; “single-page app” describes an interface architecture. A PWA may use a single-page design or another structure.

What the PWA label does not promise
- That the app works fully offline.
- That every browser offers installation or the same installation process.
- That notifications, background operation, or any particular device integration are available everywhere.
- That the app is automatically secure, fast, or equivalent to a native app. Those qualities depend on the implementation and need to be assessed separately.
- That the app must be downloaded from an app store.
