App-quality experience. No app store required.
Users don't download apps for things they use occasionally — the friction of the app store kills acquisition before it starts. A Progressive Web App gives you native-quality UX directly from a browser URL: offline capability, push notifications, home screen installation, and instant load times. For businesses that need app-like functionality without the cost of maintaining parallel iOS and Android codebases, PWAs close most of the gap at a fraction of the investment — and your users reach it via a link, not an app store search.
A Progressive Web App delivers native-quality UX directly from a browser URL — offline capability, push notifications, home screen installation, and instant load times — without the cost of maintaining separate iOS and Android codebases. Origin Softwares builds PWAs with offline-first architecture and 95+ Lighthouse PWA scores.
What is a Progressive Web App and how does it differ from a native app?
A Progressive Web App is a website that behaves like a native app — it installs to the home screen, works offline, sends push notifications, and loads instantly on repeat visits. Unlike native apps, PWAs are accessed via a URL (no app store download), work across iOS and Android from a single codebase, and update automatically. The gap between PWA and native has narrowed significantly — the remaining limitations are deep OS integration features most business apps do not need. Origin Softwares builds PWAs with offline-first service worker architecture, achieving 95+ Lighthouse PWA scores and sub-1-second repeat-visit load times. Service workers cache critical assets and API responses, so users on 3G connections still get a functional, fast experience.
The problems this solves
- Maintaining separate iOS and Android codebases is too expensive for the use case
- App store download friction killing user acquisition for casual or occasional-use apps
- Users need offline capability but the current web app requires connectivity
- Push notification requirement for re-engagement but native app maintenance is not justified
- Mobile web experience feels slow and unreliable compared to installed apps
- Field workers need app functionality in low-connectivity environments without app store access
Business outcomes
- 60% reduction in bounce rate versus non-PWA mobile web experiences
- 3x higher re-engagement via push notifications compared to email
- Single codebase for all platforms eliminating dual maintenance cost
- No app store submission delays — deploy updates instantly
- Sub-1-second repeat-visit load time after service worker installation
- Broader reach through URL sharing versus app store discovery

When should you build a PWA instead of a native mobile app?
Build a PWA when your audience is web-first, when you need broad reach without app store friction, when your core functionality works well in a browser, and when your budget does not support maintaining three codebases (iOS, Android, web). PWAs are right for e-commerce, productivity tools, content platforms, field service tools, and any application where offline capability matters but deep device integration (AR, health data, complex hardware) does not. Origin Softwares recommends honestly between PWA and native based on your specific device API requirements and user behaviour. Skipping the app store also eliminates the 15–30% platform fee on in-app purchases, which significantly changes the economics for subscription products.

Why Origin for Progressive Web App Development
Offline-first, not offline-compatible
We design the data flow and caching strategy before writing any code. The app works offline by default — connectivity is an enhancement, not a requirement.
Platform-specific capability mapping
iOS and Android behave differently for PWA features. We deliver a capability matrix at the start of every project so you know exactly what works where, with no surprises at testing.
App shell architecture for instant loads
The interface skeleton loads from cache in under 200ms on repeat visits. Users see a responsive shell immediately — data fills in as it arrives. This is what 'instant' actually means.

Before you start — a checklist
Use this to prepare for your first conversation with us.
- Determine which device APIs you actually need — most business apps do not require native-only features
- Assess your audience's platform split (iOS vs Android) and iOS push notification requirements
- Define what offline functionality is required versus nice-to-have
- Decide whether app store presence is required for brand credibility
- Confirm that a URL-based distribution model works for your acquisition strategy
- Identify the data sync strategy for content created offline
Maintenance & support
- Service worker health monitoring and cache strategy updates
- Push notification delivery monitoring and optimisation
- iOS and Android OS compatibility testing after major releases
- Performance monitoring and Lighthouse score tracking
- Bug fix SLA — critical within 24 hours
- Annual PWA capability review as browser APIs expand
“We were spending ₹40 lakhs a year maintaining separate iOS and Android apps. Origin built us a PWA that our users install from the website, gets push notifications, and works offline. App store reviews went from mixed to 4.8 stars because the experience is actually faster.”
Frequently asked questions
Planning & scope
- How much does a PWA cost compared to native apps?
- A PWA typically costs 40–60% of what separate iOS and Android native apps would cost because you maintain one codebase. Ongoing maintenance is also cheaper — no app store submissions, no dual testing, no separate release cycles. The trade-off is the capability limitations on iOS. We scope PWA projects after confirming that the feature requirements fall within what browser APIs support.
- Does a PWA work properly on iOS?
- Yes, with some nuances. iOS supports core PWA capabilities since iOS 16.4 including push notifications and home screen installation. Some limitations remain — background sync is less reliable than Android, and storage quotas are more restrictive. We deliver a capability matrix at project start that documents exactly what works on each platform so there are no surprises during testing.
Technical
- How does the app work without an internet connection?
- Service workers cache the app shell, static assets, and pre-fetched content so the interface loads instantly without connectivity. For dynamic data, we implement optimistic UI updates — the user's action is recorded locally in IndexedDB and synced when connectivity returns. Conflict resolution handles the case where the same data was modified both offline and on the server.
- How do push notifications work on a PWA?
- Web Push API with Firebase Cloud Messaging for delivery infrastructure. Users grant notification permission through a browser prompt. Notifications work on both Android and iOS (since 16.4) when the PWA is installed to the home screen. We implement user preference management so notifications can be segmented and users control what they receive.
Engagement & process
- Can you convert our existing website into a PWA?
- Yes — adding PWA capabilities to an existing website is a common engagement. We add a service worker for offline support and caching, configure the web app manifest for installation, and implement push notifications. The scope depends on how much offline functionality is needed — basic offline access is simpler than a full offline-first data layer. We assess your existing architecture and recommend the appropriate level.
- How do updates work — does the user need to do anything?
- PWA updates are automatic. When we deploy a new version, the service worker detects the change and updates the cached assets. Users get the new version on their next visit without any manual action. For critical updates, we can prompt users to refresh. There is no app store review delay — updates are live as soon as they are deployed.
