Progressive Web Apps (PWA)

Fast, reliable websites that work like mobile apps on any device—even when there's no internet.

Deliver app like experiences directly through the web with Progressive Web Apps. Our PWA development services create fast, reliable, and engaging websites that work smoothly across all devices and platforms. Users can install your website on their home screen, access content quickly, and continue using key features even with limited or no internet connection. This improves accessibility and keeps users connected to your brand at all times. By combining modern web technologies with strong performance optimization, we build PWAs that increase engagement, improve loading speed, and provide a seamless experience similar to native mobile apps.

PWAs make the most commercial sense when a business needs the functionality and engagement of a native app but wants to avoid the cost of building and maintaining separate iOS and Android codebases — and the discovery barrier of app store submission. E-commerce brands looking to reduce cart abandonment on slow mobile connections, media companies delivering content to users with inconsistent internet access, enterprise teams deploying internal tools across a mixed device fleet, and service businesses re-engaging customers with push notifications — these are all situations where a well-built PWA delivers measurable returns without the overhead of a full native app programme.

Our PWA development process covers technical architecture, service worker strategy, caching design, offline functionality, push notification setup, backend API integration, performance auditing, and cross-browser testing in one structured engagement. We help businesses convert existing websites into PWAs, build new ones from the ground up, and migrate legacy applications to modern, performant architectures — with Lighthouse scores and real-world usability as the primary benchmarks, not just feature completion.

Key Takeaways

PWAs are the right choice when you need native app engagement — offline access, home screen installation, push notifications — without the cost of building and maintaining separate iOS and Android codebases or the friction of app store discovery.
Service workers are the technical foundation of every PWA — their caching strategy directly determines how the app behaves offline, how fast it loads on repeat visits, and how reliably it performs on slow or intermittent networks.
PWAs are fully indexable by search engines, which gives them a discoverability advantage over native apps and makes SEO investment transferable directly into the application experience rather than split across a website and a separate app listing.
Core Web Vitals performance metrics have a direct relationship with conversion rates in e-commerce PWAs — a well-optimized PWA consistently outperforms a slow native app on the same device, and small improvements in load time translate to measurable changes in completed purchases and session depth.

Lightning Fast Performance

Optimized loading speeds and smooth navigation across all devices.

Offline Access

Users can access key features even without an active internet connection.

Installable Experience

Allow users to install your web app directly from their browser.

Our Strengths

Why Progressive Web Apps?

PWAs combine the best of web and mobile to deliver seamless user experiences.

Buoyancy Software builds Progressive Web Apps with performance as the primary design constraint, not a post-launch concern. Our team brings practical experience across e-commerce PWAs, enterprise portals, media applications, and legacy site migrations — using service workers, smart caching strategies, and modern frontend frameworks to deliver measurable improvements in load time, engagement, and conversion.

Optimized assets and smart caching ensure fast load times. PWAs leverage service workers to cache critical resources, enabling instant page loads even on slow networks. Our optimization techniques include code splitting, lazy loading, and image compression that reduce initial load times by up to 70%.

Push notifications and installability increase user retention. PWAs can be installed directly from the browser, appearing on home screens alongside native apps. Push notifications re-engage users with timely updates and personalized content.

Single codebase reduces development and maintenance expenses. Unlike native apps requiring separate iOS and Android development, PWAs use one codebase for all platforms. This reduces development time by 60% and ongoing maintenance costs significantly.

Accessible across devices without requiring app store downloads. PWAs work on any device with a modern browser, eliminating app store barriers and installation friction. Users can access your PWA immediately through a URL, increasing conversion rates by removing download steps.

PWAs are discoverable by search engines, driving organic traffic unlike native apps. Search engines index PWA content, enabling users to find your application through web searches.

Service workers enable offline functionality and reliable performance in poor network conditions. PWAs continue working when connectivity is lost, caching content for offline access.

What is a Progressive Web App and how is it different from a regular website?

A Progressive Web App is a website built with a specific set of web technologies — service workers, a web app manifest, and HTTPS — that enable it to behave more like a native mobile app. Unlike a standard website, a PWA can be installed to a device home screen, load instantly on repeat visits through cached assets, work offline or on poor connections, and send push notifications. The user experience is closer to an app than a webpage, but it is delivered through the browser and indexed by search engines like any other web content.

Do PWAs work on iOS devices as well as Android?

Yes, PWAs work on iOS, though with some limitations compared to Android. iOS supports home screen installation, offline caching via service workers, and basic push notifications through Safari. However, certain browser APIs are more restricted on iOS than on Chrome for Android — background sync and some advanced notification features have limited or delayed support. We test across both platforms during development and design the offline and notification experience around what iOS and Android actually support, so users on both platforms get a reliable experience.

When should we choose a PWA over a native mobile app?

A PWA is typically the better choice when your primary goal is reach and accessibility rather than deep device hardware integration. If your application does not require access to features like Bluetooth, NFC, advanced camera controls, or health sensors, and your team wants to maintain a single codebase rather than separate iOS and Android apps, a PWA usually delivers equivalent user experience at significantly lower build and maintenance cost. Native apps make more sense when the application depends heavily on device-native APIs, needs to be distributed through enterprise MDM, or requires offline-first functionality that goes beyond browser caching limitations.

How do you measure PWA performance after delivery?

We use Google Lighthouse as the primary audit tool, targeting scores above 90 across performance, accessibility, best practices, and SEO. Beyond Lighthouse, we monitor Core Web Vitals — Largest Contentful Paint, Cumulative Layout Shift, and Interaction to Next Paint — through real user monitoring rather than just lab tests. For e-commerce PWAs, we track conversion impact alongside technical metrics, because a performance improvement that does not affect engagement or revenue is less valuable than one that does. We provide a performance baseline before delivery and a post-launch benchmark report as standard.

Can our existing website be converted into a PWA?

In most cases, yes. If your website is built on a modern frontend framework like React or Angular, adding PWA capabilities — service workers, a manifest file, offline caching, and push notifications — is a structured but manageable upgrade. If it is a legacy site built on older technology, we assess whether a targeted modernization or a rebuild is the more cost-effective path. Either way, we scope the migration based on your current architecture, your performance targets, and the specific PWA features that will deliver the most value for your users.

Fast, reliable websites that work like mobile apps on any device—even when there's no internet.
