What Is Progressive Web App Development?

A progressive web app turns your existing website into something that genuinely behaves like a native app. Users can install it on their home screen, open it offline, and get push notifications -- none of which require an app store download. We handle service workers, Web App Manifest configuration, and caching logic through Workbox. The payoff: faster load times, no download friction, and an experience that holds up whether someone's on fiber or a shaky coffee shop connection.

Waar projecten falen

Native app development runs $80K–$200K per platform That budget disappears fast when you're maintaining separate iOS and Android codebases with separate teams.
Mobile web users leave the moment their connection drops Every subway commute, rural visit, and dead zone costs you revenue.
App store approvals take weeks and throttle your release cycle Bug fixes and new features sit in review queues instead of reaching users.
Bounce rates on slow 3G connections exceed 50% Service worker caching would make repeat visits feel instant -- but only if someone's actually implemented it.
Without push notifications, you've got no way to re-engage anonymous web visitors You're stuck depending entirely on email lists and paid retargeting.
Your site scores below 40 on Lighthouse's PWA audit No manifest, no offline fallback, nothing telling browsers it's installable.

Compliance

Service Worker Architecture

Custom service worker strategies -- cache-first for static assets, network-first for API calls, stale-while-revalidate for content pages. Built with Workbox so the caching logic stays maintainable six months from now, not just on launch day.

Offline-First Data Layer

IndexedDB-backed offline storage that queues actions and syncs when connectivity returns. Users can fill out forms, save items, and browse content without needing a live connection.

Push Notification System

Web Push API integration with subscription management, segmented campaigns, and quiet hours. The backend handles VAPID keys and delivery analytics so you're not flying blind on what's actually landing.

App Store Deployment

PWABuilder and Trusted Web Activity packaging for the Google Play Store, Microsoft Store, and Samsung Galaxy Store. One codebase, multiple distribution channels.

Web App Manifest Optimization

A complete manifest with adaptive icons, splash screens, display modes, and share target configuration -- the stuff that actually triggers browser install prompts on qualifying visits.

Background Sync & Updates

Background sync handles failed requests automatically. Skipwaiting and clients.claim strategies make sure users always run the latest version, with no stale cache surprises two weeks after you've shipped a fix.

Wat we bouwen

Precaching & Runtime Caching

Workbox precaches critical assets at install and applies runtime strategies per route for instant navigation.

Install Prompt UX

Custom beforeinstallprompt handling with contextual triggers that convert 3–5x better than the browser's default install banner.

Offline Fallback Pages

Branded offline pages with cached content and search, so users never hit the Chrome dinosaur screen.

Asset Versioning & Cache Busting

Content-hashed cache keys with automatic cleanup when the service worker updates.

Adaptive Loading

The Network Information API detects connection quality and adjusts -- smaller images on 3G, full resolution on Wi-Fi. It's a small thing that makes a noticeable difference.

Analytics Without Network

Offline analytics queue in IndexedDB and replay to Google Analytics or Plausible once connectivity returns, so you're not losing conversion data every time someone goes underground.

Ons proces

01

PWA Audit & Strategy

We start by auditing your existing site against the Lighthouse PWA checklist, mapping your offline use cases, and figuring out where push notifications actually make sense for your users. Then we implement Workbox-powered service workers with route-specific caching and configure your Web App Manifest -- icons, display mode, scope, all of it.
Week 1
02

Service Worker & Manifest Build

From there, we build offline fallback pages, an IndexedDB sync layer, and the full push notification subscription flow with backend delivery infrastructure.
Week 2–3
03

Offline Experience & Push Integration

We generate TWA packages for Google Play and PWABuilder packages for the Microsoft Store, configure digital asset links, and get store listings set up.
Week 4–5
04

App Store Packaging

Then comes cross-device testing across Android, iOS, and desktop -- offline scenarios, push delivery rates, install funnel conversion. You get 30 days of post-launch tuning included, because something always needs a tweak in the real world.

Testing, Launch & Optimization

A PWA is a web application that combines service workers, a manifest file, and HTTPS to deliver an app-like experience -- installable, offline-capable, and push-enabled. Unlike native apps, PWAs share one codebase across all platforms, skip app store review cycles, and update instantly. Users reach them through a URL or a home screen icon.

Veelgestelde vragen

What is a progressive web app and how is it different from a native app?

Yes, with some caveats. Safari supports service workers, offline caching, and home screen installation. Push notifications, though, require iOS 16.4 or later, and background sync is still restricted. We use feature detection throughout so the PWA degrades gracefully on older iOS versions while delivering full functionality on Android and desktop.

Do PWAs work on iOS and Safari?

Yes. We package your PWA as a Trusted Web Activity using Bubblewrap or PWABuilder, which wraps it in an Android shell without embedding a WebView. The Play Store listing opens your PWA in Chrome with no browser chrome visible. We also target the Microsoft Store and Samsung Galaxy Store.

Can a PWA be listed on the Google Play Store?

Service workers intercept network requests and serve cached responses, cutting out server round trips on repeat visits. Workbox supplies battle-tested strategies — precaching critical assets at install, runtime caching for API responses, stale-while-revalidate for content that changes occasionally. Repeat page loads typically drop below one second.

How do service workers and Workbox improve performance?

Web push reaches users on Android, Windows, macOS, and iOS 16.4+ even when your site isn't open. We trigger permission prompts at meaningful moments — after a purchase, a saved item, account creation — and typically see opt-in rates of 10–15%. Segmented campaigns drive repeat visits without burning budget on email or paid ads.

Will push notifications work for re-engaging users?

A PWA build on an existing Next.js site takes 6–8 weeks and starts at $8,000. Greenfield projects with custom offline data sync, push infrastructure, and app store packaging run $14K–$25K. Every engagement includes a Lighthouse PWA audit, cross-device testing, and 30 days of post-launch support.
