Progressive Web App (PWA) Development
Fast, Installable, Offline-Capable Web Applications That Work Like Native Apps on Every Device
We provide Progressive Web Application (PWA) Development services that build modern web applications combining the reach of the web with the capabilities of native mobile apps. PWAs are installable on any device, load instantly on repeat visits, work reliably in poor network conditions, deliver push notifications, and provide an immersive full-screen experience — all from a single web codebase that works on every platform without separate app store submissions.
Are you looking to deliver a mobile app-quality experience to your users without the cost of building and maintaining separate iOS and Android native apps? Or do you have an existing web application that performs poorly on mobile and struggles with slow connections? Techmits IT Solutions builds PWAs that solve both challenges — delivering outstanding mobile performance while maintaining the universal accessibility of the web.
We deliver PWA development for businesses across India, the UK, Australia, the USA, Canada, UAE, and the Middle East — building customer-facing e-commerce PWAs with offline product browsing, field service PWAs that work in remote locations with poor connectivity, internal business tool PWAs that replace slow traditional web applications, and consumer app PWAs that rival native apps in experience and performance.
Why Choose Techmits for PWA Development?
Building a true Progressive Web App — not just a "mobile-friendly website" — requires expertise in service workers, caching strategies, Web APIs, and performance engineering. At Techmits IT Solutions, we build PWAs that genuinely deliver on the promise of offline capability, instant loading, and app-like experience — and that score highly on PWA audit tools like Google Lighthouse.
Offline Functionality
We implement service worker caching strategies that enable your PWA to work fully or partially offline — giving users uninterrupted access to content and functionality even in poor or no network conditions.
App-Like Performance
We engineer PWAs for instant loading — optimised bundle sizes, aggressive caching, skeleton screens, and optimistic UI updates — delivering the snappy, responsive experience users expect from native apps.
Push Notifications
We implement web push notifications that reach users even when the PWA is not open — enabling re-engagement, alerts, and time-sensitive communications without requiring a native app install.
Device Installation
We implement add-to-home-screen functionality so users can install your PWA on their device — making it accessible from the home screen with an app icon, full-screen mode, and no visible browser UI.
Single Codebase
PWAs work across all platforms — iOS, Android, Windows, macOS — from a single codebase, eliminating the cost and complexity of maintaining separate native apps for each platform.
SEO & Discoverability
Unlike native apps, PWAs are indexable by search engines — making your application discoverable through organic search and driving user acquisition without dependency on app store rankings.
How We Build Progressive Web Apps
Our PWA Development Process
Requirements & PWA Assessment
We assess your use case, offline requirements, performance targets, and device capabilities — determining the right PWA architecture and caching strategy for your specific application.
App-First UX Design
We design your PWA UX with app conventions in mind — navigation patterns, gesture interactions, and visual design that feel native rather than web-page-like.
Application Development
We build your PWA using modern web technologies — HTML5, CSS, and JavaScript frameworks — with clean architecture that supports ongoing feature development.
Service Worker Implementation
We implement and tune service workers — defining caching strategies, offline fallbacks, and background sync behaviours appropriate for each type of content in your application.
Manifest & Installability
We configure the web app manifest, app icons, splash screens, and theme colours — ensuring your PWA can be installed on every major platform with a native app appearance.
Lighthouse Auditing
We run Lighthouse PWA audits throughout development — addressing performance, accessibility, SEO, and PWA compliance issues until your application scores highly across all dimensions.
Deployment
We deploy your PWA to HTTPS hosting (required for service workers), configure CDN, and implement monitoring for performance and availability.
Optimisation
We monitor Core Web Vitals, analyse user engagement, and continuously optimise PWA performance — improving loading speed, offline reliability, and user experience over time.
Everything You Need to Know About Progressive Web App Development
Get answers to questions about PWA capabilities, offline functionality, iOS and Android support, push notifications, performance standards, and when a PWA is the right choice versus a native app.
What is a Progressive Web App and how is it different from a regular website?
A Progressive Web App is a web application built using modern browser APIs to deliver app-like capabilities — offline functionality through service workers, home screen installation, push notifications, full-screen mode, and fast-loading performance. A regular website requires a network connection for every page visit, cannot send push notifications, and cannot be installed on a device. A PWA bridges this gap, delivering app experiences through the web browser without requiring app store distribution.
Do PWAs work on iOS (iPhone and iPad)?
Yes, PWAs work on iOS, though with some limitations compared to Android. iOS supports add-to-home-screen installation, full-screen mode, and service worker caching. Push notifications on iOS were added in iOS 16.4 for installed PWAs on recent devices. For most PWA use cases — fast loading, offline content, installability — iOS support is now very good. We design PWAs to work excellently on both iOS and Android, and we communicate clearly about any feature limitations on specific platforms.
What types of applications work best as PWAs?
PWAs work best for applications where fast loading, mobile access, and offline capability are important — e-commerce and product catalogues, news and content applications, productivity tools, field service applications, customer portals, and consumer apps with regular return visits. Applications requiring access to advanced device hardware (camera, GPS, Bluetooth, sensors) or with complex background processing requirements may be better served by native apps in some cases.
Can an existing web application be converted to a PWA?
Yes. Converting an existing web application to a PWA involves adding a service worker, creating a web app manifest, ensuring HTTPS, optimising performance, and adapting the UX for mobile. The effort depends on the quality and architecture of the existing codebase — a well-structured modern web application can be PWA-enhanced relatively quickly; an older, poorly-structured application may require more substantial refactoring.
How does a PWA compare in performance to a native app?
Well-built PWAs can match or approach native app performance for most use cases — especially for content-driven and data-driven applications. Native apps may have an edge for graphics-intensive applications (games, complex animations) and applications requiring deep device hardware integration. For the majority of business and consumer application use cases, a well-engineered PWA delivers excellent performance that most users cannot distinguish from a native app experience.
Can we publish our PWA to the Google Play Store or Apple App Store?
Yes. PWAs can be published to the Google Play Store using Google's Trusted Web Activity (TWA) mechanism, which wraps the PWA in a thin native shell for store distribution. Apple's App Store can also distribute PWAs, though the process is more restrictive. However, one of the main advantages of PWAs is that they do not require app store submission — users can install directly from the website, avoiding app store fees, review processes, and update delays.
How do PWA push notifications work?
PWA push notifications use the Web Push API — a browser standard that enables web applications to send notifications to users' devices even when the browser is closed. Users must grant notification permission explicitly. When a push event is sent from your server, the browser's push service delivers it to the user's device and the service worker displays the notification. This works across Android devices reliably; iOS 16.4+ supports it for installed PWAs. We implement push notifications as part of PWA development when they are required by your use case.
