Progressive Web App Development Services: PWA Development Company

Updated September 2026 · Written and maintained by the Progression Agency strategy team

Progression Agency provides progressive web app development: web applications that install to the home screen, work offline, send push notifications and load fast on any device, from one codebase, without an app store in the way. On new builds we work as a progressive web application development company; when an existing site needs converting, we step in as a progressive web app development agency, the progressive web app agency partner doing the conversion.

What is a progressive web app?

A progressive web app is a web application that uses modern browser capabilities, a web app manifest and a service worker so it can be installed, work offline, run full-screen and send notifications, while remaining a normal, linkable, indexable website.

Publicly described examples of progressive web apps include Starbucks’ ordering PWA, Pinterest’s mobile web app and Uber’s m.uber.com; each chose the web to reach users on low-end devices and slow networks without an install step. See web app development and cross-platform app development for the alternatives.

PWA development services

Projects we are most often asked to build. A progressive web app development service covers the app shell, offline behavior, installability and the API behind it, so ask any provider to describe each of the four. Progressive web application developers should also explain how caching, offline pages and updates will be handled before any code is written, since the rest of the build depends on those choices.

New progressive web apps

Ordering, booking, content and internal-tool PWAs built with React or Next.js, a manifest and a service worker.

Converting a website into a PWA

Adding installability, offline caching and notifications to an existing site without a rebuild.

Offline-first business apps

Field and retail tools that keep working without a connection and sync when it returns.

Push notification strategy

Permission flows and campaigns that re-engage without annoying users, including iOS web push.

Performance engineering

Core Web Vitals, app-shell architecture and caching that make the app feel native.

Choosing a progressive app development company

Searches for a progressive app development company usually mean a progressive web app builder. Look for one that can show installable apps working offline, explain what a PWA cannot do compared with a native app and measure load time on real devices.

Where the value usually comes from.

Platform capabilities and limits

PWAs can do most of what business apps need; the limits are worth knowing before you choose.

• Capabilities and browser support are documented at web.dev and MDN.
• iOS supports installed PWAs and web push (iOS 16.4 and later) with some limits compared with native apps.
• Deep hardware access such as Bluetooth or background location is limited on some platforms; we say when native is the better route.
• A PWA can also be packaged for the app stores where store presence matters.

PWAs can also reach Windows users beyond the browser. A Microsoft PWA can be installed from Microsoft Edge as a standalone app window, and tools such as PWABuilder can package a PWA for the Microsoft Store, so PWA Microsoft distribution is an option when your customers work on Windows desktops. Support for specific features differs by browser and operating system, so check each capability you rely on. That is why progressive development starts with a baseline that works in every browser and adds install and offline features only where the browser supports them.

Is a PWA still worth building?

Is PWA still used today? Yes, mainly where one web codebase has to serve many devices, install easily and work with a weak connection. Claims about why PWA is the future go further than the evidence: PWAs do not replace native apps for deep hardware access or app store discovery. A PWA is worth building when your users are already on your website, when updates must ship instantly and when a store listing is not essential.

Our progressive web app development process

We confirm the users and devices, decide the offline and caching strategy, design a responsive installable interface, build the manifest, service worker and app, test on real devices and with Lighthouse, launch on HTTPS with install prompts and measure installs and engagement.

How much does progressive web app development cost?

At market rates, converting an existing site into a PWA commonly costs $10,000-$30,000, a new business PWA $25,000-$80,000 and an offline-first operational app $60,000-$120,000.

Technology we typically use

Mainstream, maintainable choices.

PWA with React and Next.js

A React progressive web app is a common starting point because React teams already know the component model. PWA with React usually means adding a web app manifest, a service worker for caching and offline pages, and a way to handle updates cleanly. Next.js adds routing, server rendering and static generation, so a Next.js PWA can keep good SEO while still installing like an app. The service worker layer is typically handled with a library such as Workbox, and the main design choice is what to cache and for how long.

When you compare a PWA framework, look at how it handles caching strategies, update prompts and testing offline behavior. The framework matters less than those decisions, and a well-built service worker is more valuable than a long feature list.

Mistakes to avoid

Common causes of overruns and low adoption.

• Choosing a PWA for features that need deep hardware access.
• No offline strategy.
• Asking for notification permission on first visit.
• Ignoring iOS-specific limits.
• Skipping Lighthouse and real-device testing.
• Using a generic PWA builder for a product that needs custom flows.
