Progressive Web App Development Company

A progressive web app is a website built to behave like an installed app: it loads on the home screen, works offline, and sends push notifications, all from a single codebase that runs in the browser. Dcrayons designs and builds PWAs using service workers, a web app manifest, and HTTPS so your product reaches users without an app store download. We are a digital marketing and web agency, founded in 2016 and based in Delhi, working across web development, SEO, and e-commerce.

How we approach pwa development

A web and marketing team that ships PWAs people actually install and reach

Step 1: Plan the app shell and offline strategy

We start by mapping which screens and data a user needs when the connection drops. That decision shapes the app shell, the cache plan, and the choice between cache-first for static assets and network-first for live data. Getting this right early is what makes a PWA feel reliable instead of just a website with extra files.

Step 2: Build with a manifest and service worker

The web app manifest defines the name, icons, theme color, and how the PWA opens once installed. The service worker is the script that intercepts network requests, serves cached responses offline, and handles background sync and push notifications. We register and version these carefully so updates roll out without leaving users stuck on a stale build.

Step 3: Make it installable and fast

For the install prompt to appear, the app needs HTTPS, a valid manifest, and a registered service worker, so we verify all three. We also tune the loading path, since Lighthouse weighs first paint and time to interactive heavily. The aim is an add-to-home-screen experience that opens full screen and starts quickly on mid-range Android phones, not just flagship devices.

Step 4: Audit, test offline, and ship

Before launch we run Lighthouse PWA and performance audits, then test real offline behavior by toggling the network and reloading. We check the install flow on Android and the more limited support on iOS Safari, where push and install behave differently. Once it passes, we deploy and set up a service worker update path so future changes reach users cleanly.

Why build your PWA with Dcrayons

Dcrayons has built and marketed web products since 2016, so we treat a PWA as both an engineering job and a reach problem. A progressive web app only earns its keep if real users find it, install it, and have it keep working when the signal is weak, which is why we pair the service worker and manifest work with the SEO and performance checks we run on every site. We are direct about the trade-offs, including the parts of iOS where PWAs do less than they do on Android, so you can decide where a PWA fits and where a native app might still be needed.

We build the full PWA stack: web app manifest, service workers, offline caching, and installability, not just a responsive site

We test offline behavior and the install flow on real Android devices, and we are honest about where iOS Safari support is limited

As an SEO and content agency since 2016, we keep the PWA crawlable and indexable so search visibility is not traded for app-like behavior
One codebase served over the web means no app store review cycle and no separate native build to maintain

Question & Answer

Frequently asked questions

Real questions people ask Dcrayons about pwa development. Honest answers, no jargon.

A progressive web app is a website built with extra capabilities so it behaves like an installed app. It can load from the home screen, work offline through a service worker, and send push notifications, all while running in the browser. It needs HTTPS, a web app manifest, and a registered service worker to qualify.

A PWA runs in the browser from one web codebase and is installed directly from a URL, with no app store download or review. A native app is built separately for iOS and Android and is distributed through the app stores. PWAs are faster to ship and update, but native apps still have deeper access to device hardware and more complete support, especially on iOS.

Yes, but with limits. iOS Safari supports add-to-home-screen and offline caching, and it added web push in recent versions for installed PWAs. However, several features behave differently or are restricted compared to Android, so we test on real iOS devices and tell you up front what will and will not work.

Yes. A service worker caches the app shell and chosen assets so the core screens load without a connection. We decide together which data should be available offline and use caching strategies like cache-first for static files and network-first for live content, plus background sync where it helps.

It should not, when built correctly. A PWA is still a web page that search engines can crawl and index, and we make sure content is server-rendered or otherwise visible to crawlers rather than locked behind client-side scripts. Because Dcrayons works in SEO daily, we keep indexability and Core Web Vitals in scope throughout the build.

We run Lighthouse, which has a dedicated audit for installability, service worker registration, and HTTPS, alongside its performance and best-practices scores. We also test offline reloads and the real install prompt on devices. A site passes when it meets the install criteria and holds up when the network is throttled or cut.
