The concept for a PWA is simple, they are websites that feel like apps. PWA sites can be accessed through any web browser, this makes them search friendly.

Take a look at just a few of the possibilities that a PWA site can deliver!

Let a Kaizen Designer create your online presence.

• Progressive — Works for every user, regardless of browser choice, using progressive enhancement principles.

• Responsive — Fits any form factor: desktop, mobile, tablet, or forms yet to emerge.

• Faster after initial loading - After the initial loading has finished, the same content and page elements do not have to be re-downloaded each time. Ordinary websites often already made use of the browser cache to avoid re-downloading the same data redundantly. But on progressive web applications, the same elements do not need to be re-rendered again.

• Connectivity independent — Service workers allow offline uses, or on low quality networks.

• App-like — Feels like an app to the user with app-style interactions and navigation.

• Fresh — Always up-to-date due to the service worker update process.

• Safe — Served via HTTPS to prevent snooping and ensure content hasn't been tampered with.

• Discoverable — Identifiable as an “application” by manifest.json^] and service worker registration, and discoverable by search engines.

• Re-engageable — Ability to use push notifications to maintain engagement with the user.

• Installable — Provides home-screen icons without the use of an App Store.

• Linkable — Can easily be shared via a URL.

The technical baseline criteria for a site to be considered a progressive web app by browsers were described by Russell in a follow-up post:

• Originate from a secure origin. Served over TLS and green padlock displays (no active mixed content).

• Load while offline (even if only a custom offline page). By implication, this means that progressive web apps require service workers.

• Reference a web app manifest with at least the four key properties: name, short_name, start_url, and display (with a value of standalone or full-screen)

• An icon at least 144×144 large in PNG format Use of vector graphics that are indefinitely scalable and require smaller file sizes.

We pretty much make any app you can think about, if we don't have a template for you, we can break open the CODE BOOK and get you what you need.

We can up your game by enabling PN via your PWA site, like "Amber alerts", you'll reach all who is subscribed, Push Notifications is the fastest way to stay connected with your customers.
