Exactly What You Get With Progressive Web App Development

No vague promises. Here is precisely what we build, configure, and hand over.

Progressive Web Apps (PWAs) are web applications that use modern web capabilities to deliver an app-like experience to users. They combine the reach of the web with the functionality of native apps — working offline, sending push notifications, and living on the user's home screen.

At Softileo, we build PWAs that deliver exceptional user experiences. We use service workers for offline functionality, web app manifests for installability, and push APIs for re-engagement. Your PWA will load fast, work reliably, and feel like a native app — without the app store friction.

What separates professional PWA development from basic web apps:

  • Service workers — scripts that run in the background, enabling offline functionality, caching, and push notifications.
  • Web app manifest — JSON file that controls how your app appears when installed on devices (name, icons, splash screen, theme colors).
  • Offline-first architecture — your app works even without internet, using cached data and syncing when connectivity returns.
  • Push notifications — re-engage users with timely updates, even when they're not actively using your app.
  • Installability — users can add your app to their home screen, launching it in its own window like a native app.
  • 90+ Lighthouse scores — we optimize for performance, accessibility, best practices, and SEO.
  • Cross-platform compatibility — works seamlessly on desktop, mobile, and tablet.

The result: a web app that users love — fast, reliable, and engaging, with the reach of the web and the capabilities of native.

Offline Functionality

Your app works without internet — users can access content, fill forms, and interact even when offline. Changes sync automatically when connection returns.

Push Notifications

Re-engage users with timely updates, offers, and alerts. Notifications work even when the browser is closed (with user permission).

Installable

Users can add your app to their home screen. It launches in its own window, feels like a native app, and has an icon just like installed software.

90+ Lighthouse Score

We optimize for performance, accessibility, best practices, and SEO. Your PWA will score 90+ on Google Lighthouse — essential for user experience and rankings.

Service Workers

Powerful background scripts that enable offline caching, push notifications, and background sync. Built with Workbox for reliability and maintainability.

Web App Manifest

Complete manifest configuration — app name, icons, splash screen, theme colors, and display settings. Your app looks perfect when installed.

Offline Data Sync

IndexedDB and background sync for storing data offline and syncing when connection returns. Perfect for forms, drafts, and user-generated content.

Responsive Design

Beautiful, responsive UI that works perfectly on desktop, mobile, and tablet. Consistent experience across all devices.

Is Progressive Web App Development Right For Your Business?

Custom web development is not for everyone. Here is an honest breakdown of when it delivers clear ROI.

PWAs are the future of web development — combining the reach of the web with the capabilities of native apps. They solve the biggest problems of traditional web apps: they work offline, they're fast, and they can re-engage users. For businesses, PWAs mean higher engagement, better conversion rates, and lower development costs than building separate native apps.

Investing in PWA development makes clear commercial sense when you recognize any of these situations:

  • Your users frequently have unreliable internet connections
  • You want to increase engagement with push notifications
  • You need an app-like experience but can't justify native development costs
  • Your current web app is slow and has poor Lighthouse scores
  • You want users to install your app without app store friction
  • Your competitors have native apps and you need to compete
  • You need to reduce development and maintenance costs (one PWA instead of iOS + Android + web)

The ROI of PWAs is well-documented. Twitter saw 65% increase in pages per session and 75% increase in Tweets sent. AliExpress saw 104% higher conversion rates for new users. Flipkart saw 70% higher re-engagement. A $10K–$40K investment in a PWA can transform your user engagement and conversion rates.

When a PWA might not be the right choice: if you need deep hardware integration (Bluetooth, NFC, advanced camera controls) or must be in the app store for discoverability, a native app may be necessary. We'll recommend the right approach for your needs.

E-Commerce PWAs

Online stores that work offline, load instantly, and convert better. Users can browse products, add to cart, and checkout even with poor connectivity.

News & Content PWAs

News sites that load instantly and work offline. Users can read articles anywhere, anytime — perfect for commuters and travelers.

Event & Booking PWAs

Event apps that work offline — users can access schedules, maps, and tickets without internet. Push notifications for updates and changes.

Restaurant PWAs

Restaurant sites with offline menus, online ordering, and push notifications for specials and order updates.

Productivity PWAs

Task managers, note apps, and project tools that work offline and sync when online. Users stay productive anywhere.

Travel & Transit PWAs

Travel apps with offline maps, itineraries, and booking information. Essential for travelers with limited data.

Fitness PWAs

Workout apps that work offline in gyms with poor signal. Track workouts, watch videos, and log progress without internet.

Education PWAs

Learning platforms that work offline — students can access course materials anywhere. Sync progress when online.

"We built an e-commerce PWA with Softileo, and the results have been incredible. Pages load instantly, users can browse even with poor connections, and our conversion rate increased by 40%. The push notifications bring users back daily. Our iOS/Android app maintenance costs are gone — we just maintain one PWA. Best decision we made."

40% increase in conversion rate — one codebase instead of three

How We Deliver Your Progressive Web App Development — Step by Step

From first call to deployment — a clear process with no surprises.

We start every PWA project with a discovery phase — understanding your users, their connectivity needs, and your engagement goals. A news PWA needs different caching strategies than an e-commerce PWA. We design the right solution for your specific needs.

How a PWA development project runs from discovery to deployment:

  • Step 1 — Discovery & Requirements (Week 1): We discuss your users, their connectivity scenarios, and engagement goals. We determine which features need offline support, what content to cache, and notification strategy.
  • Step 2 — Architecture & Design (Week 1-2): We design the service worker caching strategy, offline data sync approach, and UI/UX. We create wireframes and designs in Figma. You approve before development.
  • Step 3 — Frontend Development (Week 2-5): We build your application with React or Vue — responsive, fast, and beautiful. Weekly demos let you see progress.
  • Step 4 — Service Worker Implementation (Week 4-6): We implement service workers with Workbox for offline caching, background sync, and push notifications. We test offline functionality thoroughly.
  • Step 5 — PWA Configuration (Week 5-6): We configure the web app manifest, icons, splash screens, and theme colors. Your app is ready to install.
  • Step 6 — Testing & Optimization (Week 6-7): We test on multiple devices, optimize for Lighthouse score, and ensure push notifications work correctly.
  • Step 7 — Deployment & Handover (Week 7-8): Production deployment, documentation, and source code handover. 90-day warranty begins.

What makes our PWA development different: we focus on the full PWA experience — not just making it technically a PWA, but making it feel like a native app. Smooth transitions, app-like UI, and seamless offline experience.
