Home-screen install where the browser and the brief allow it

PWA development
Installable web apps when a store listing is not required. Offline, home-screen and browser in one product.
Build
A website that can behave like an app
A progressive web app is a website that can install, cache and behave like an application when that is the right delivery. SJ Technologies designs, builds, tests and integrates PWAs when a store listing is not required, or when the same product must work in the browser and on a home screen.
Offline and install behaviour are decisions in the brief, not a default. We add a service worker, a manifest and caching only where they earn their keep. A brochure site does not become a PWA by adding a badge.
Migration from a site or from a native app is in scope when that is the shorter path. The stack is chosen from the requirement, not from a favourite toolkit.

Cached journeys only for the tasks that must work without a signal
The same product in the browser and on a phone, without two codebases
When App Store or Play review would delay a product that does not need it
When a PWA is the honest choice
The browser is the product
Staff or customers already work in a tab. Install is a convenience, not a store listing.

Ship on the web so a depot or clinic does not wait on store review. Native can follow.

Background location, Bluetooth, payments in-app or a store feature a PWA cannot support.

From a site that already works, or from a native app you no longer want to maintain on two stores.
What we put in a PWA scope
PWA design, development, testing and integration. Offline and install behaviour only where the brief needs it. Migration from a site or a native app when that is the shorter path. The stack is chosen from the requirement, not from a favourite toolkit.
