Progressive Web Apps - PWA

Progressive Web Apps are user experiences that have the reach of the web, and are. This new level of quality allows Progressive Web Apps to earn a place on the user's home screen.

Reliable

Load instantly and never show the downasaur, even in uncertain network conditions.

Fast

Respond quickly to user interactions with silky smooth animations and no janky scrolling.

Engaging

Feel like a natural app on the device, with an immersive user experience.

Reliable

When launched from the user’s home screen, service workers enable a Progressive Web App to load instantly, regardless of the network state.


A service worker, written in JavaScript, is like a client-side proxy and puts you in control of the cache and how to respond to resource requests. By pre-caching key resources you can eliminate the dependence on the network, ensuring an instant and reliable experience for your users.

Fast

53% of users will abandon a site if it takes longer than 3 seconds to load! And once loaded, users expect them to be fast—no janky scrolling or slow-to-respond interfaces.

Engaging

Progressive Web Apps are installable and live on the user's home screen, without the need for an app store. They offer an immersive full screen experience with help from a web app manifest file and can even re-engage users with web push notifications.


The Web App Manifest allows you to control how your app appears and how it's launched. You can specify home screen icons, the page to load when the app is launched, screen orientation, and even whether or not to show the browser chrome.
