When a web application should be a PWA

We treat PWA as an architectural option for a web application, not a separate project type. The choice depends on use cases, target devices and offline requirements.

Installation on the device

We add a web app manifest, icons and a reliable install flow so users can launch the application from their home screen without an app store.

Offline and unstable network

We design caching of the interface and data through a service worker, determine secure synchronization scenarios after the connection is restored.

Performance & Updates

We control client-side bundle size, Core Web Vitals and cache updates so users never get stuck on an outdated version.
