PROGRESSIVE WEB APPS

Progressive Web Apps With Native Feel

Deliver app-like experiences through the browser. InterCode builds progressive web apps that work offline, send push notifications, and install on home screens without app store friction.

App-Like Experiences Without App Stores

Progressive web apps bridge the gap between websites and native apps. InterCode builds PWAs that load instantly, work offline, and feel like native applications while being accessible through a simple URL. No app store approval process, no separate codebase to maintain, and no forced update cycles.

Our PWA development leverages modern browser capabilities including service workers for offline caching, Web Push API for re-engagement notifications, and Web App Manifest for installable home screen experiences. We combine these technologies with React and Next.js to create fast, reliable applications that work on any device.

PWAs are ideal for content platforms, field service applications, internal tools, and any scenario where you want mobile app engagement without the cost and complexity of native development. InterCode designs PWAs that pass Lighthouse audits with flying colors and deliver measurably better user engagement than traditional websites.

Our PWA Development Process

1

PWA Strategy & Planning

We identify which PWA capabilities deliver the most value for your use case and audience.

  • Offline scenarios mapping
  • Push notification strategy
2

App Shell Architecture

Build the fast-loading app shell that provides instant navigation and a native-like feel.

  • Critical CSS inlining
  • Route-based code splitting
3

Service Worker Implementation

Implement caching strategies, offline fallbacks, and background sync for reliable offline experiences.

  • Workbox configuration
  • Cache versioning and cleanup
4

Push & Installation

Set up push notification infrastructure and Web App Manifest for installable experiences.

  • Push subscription management
  • Install prompt optimization
5

Testing & Lighthouse Audit

Comprehensive testing across devices and network conditions with Lighthouse PWA audit pass.

  • Offline and slow network testing
  • PWA installability verification

Technologies We Use

Modern web platform APIs and frameworks for production-grade PWAs.

We build on standard web platform APIs (Service Workers, Web Push, Cache API) with Workbox for reliable caching patterns and React for component-driven UIs that feel native on every device.

Why InterCode for Progressive Web Apps

Instant Loading

Service worker caching and app shell architecture deliver sub-second load times even on slow networks.

True Offline Support

Not just cached pages but fully functional offline experiences with data sync and conflict resolution.

Native-Like Quality

Smooth animations, gesture support, and platform-aware UI that users cannot distinguish from native apps.

Cost-Effective

One codebase for all platforms means faster development, easier maintenance, and lower total cost of ownership.

Frequently Asked Questions

PWAs run in the browser and are built with web technologies, while native apps are built with platform-specific languages and distributed through app stores. PWAs can now do most things native apps can, including offline access, push notifications, and home screen installation, but at lower development cost.

Yes. iOS supports PWA installation, offline caching, and most PWA features. Push notifications on iOS require iOS 16.4 or later. We design our PWAs to provide the best possible experience on both iOS and Android while gracefully handling platform differences.

For many use cases, yes. PWAs are ideal when you need broad reach, fast updates, and lower development costs. Native apps still have advantages for hardware-intensive features, background processing, and app store discovery. We evaluate your requirements and recommend the right approach.

Service workers intercept network requests and serve cached responses when offline. We implement smart caching strategies that pre-cache critical assets and dynamically cache frequently accessed content. For data-heavy apps, we use IndexedDB for local storage with background sync.

Yes. PWAs are regular web pages that search engines can crawl and index. Combined with fast load times and good Core Web Vitals scores, PWAs often rank better than slow traditional websites. Unlike native apps, all your content remains accessible to search engines.
