What we build

PWA Development Services

01

Offline-First PWA Development

PWAs that work without an internet connection using service workers and IndexedDB for local data storage.

02

Service Worker Implementation

Custom service worker strategies using Workbox for intelligent caching, background sync for deferred actions, and periodic background fetch. We implement cache-first, network-first, and stale-while-revalidate patterns based on your content type.

03

Push Notifications

Web push notifications for re-engagement that work on Android, iOS (since iOS 16.4), and desktop browsers.

04

App Shell Architecture

Instant-loading app shell pattern that caches the UI framework and loads dynamic content on demand. This architecture delivers sub-second initial load times and smooth navigation that feels indistinguishable from a native app.

05

Web App Manifest Configuration

Complete manifest configuration for home screen installation, splash screens, theme colors, and display modes. We configure standalone display mode for full-screen app experience and shortcuts for quick actions directly from the home screen.

06

Advanced Cache Strategies

Sophisticated caching with Workbox including runtime caching, precaching of critical assets, cache versioning with automatic cleanup, and range request handling for media. Our strategies minimize bandwidth usage while ensuring content freshness.

How it works

Our process

  1. Discovery & PWA Strategy

    We analyze your business goals, target audience, and offline requirements to determine the optimal PWA architecture, caching strategy, and feature set for maximum engagement.

  2. UI/UX Design

    Simon designs responsive, app-like interfaces that work consistently across desktop, tablet, and mobile with touch-first interactions, smooth transitions, and offline state handling.

  3. PWA Development

    Simon builds your PWA using Vue.js and Nuxt with Workbox for service worker management, implementing app shell architecture, background sync, and push notification integration.

  4. Performance & Offline Testing

    Testing with Lighthouse for PWA compliance scoring, Chrome DevTools for service worker debugging, and real-device testing across browsers to ensure consistent offline behavior and sub-second load times.

  5. Deployment & Distribution

    We deploy your PWA to a CDN with HTTPS, configure the web app manifest for installability, and optionally publish to Google Play Store via Trusted Web Activity (TWA) for additional distribution.

  6. Monitoring & Optimization

    Ongoing performance monitoring with Core Web Vitals tracking, service worker updates, cache invalidation management, and iterative improvements based on user engagement analytics.

Questions

Frequently asked questions

What is a Progressive Web App (PWA)?

PWAs are installable on the home screen without an app store, work offline using service workers, support push notifications, and load instantly with app shell architecture.

PWA vs native app: which should I choose?

Choose a PWA if you need broad reach across all devices, SEO visibility, and lower development costs. Choose a native app if you need advanced hardware access (Bluetooth, NFC, ARKit), App Store/Play Store distribution, or maximum performance for graphics-intensive features. App369 can also build a PWA alongside a native Flutter app for maximum coverage.

How much does PWA development cost?

Cost depends on scope, platforms and integrations. Our rates are published on the fee structure page, and the free app cost calculator gives a range for a progressive web app with every assumption listed. We send a fixed quote after reviewing your brief.

Do PWAs work offline?

Yes. Service workers intercept network requests and serve cached responses when the network is unavailable. Strategies include cache-first for static assets, network-first for dynamic content, and stale-while-revalidate for balanced freshness. IndexedDB provides offline data storage for complex datasets. App369 implements Workbox for robust caching strategies.

Which browsers support PWAs?

App369 implements progressive enhancement to ensure the best possible experience on each browser.

Can PWAs access device features like camera and GPS?

Yes. Push notifications are supported on both Android and iOS (since iOS 16.4). Bluetooth and NFC access is available in Chromium-based browsers.
