Which caching strategy will you use for our app?

It depends on the route, so we choose per asset type rather than applying one rule everywhere. The app shell and static assets usually go cache-first with versioned precaching. API data that must be current goes network-first with a cached fallback. Content that can be slightly stale suits stale-while-revalidate. Getting this wrong is the most common cause of a broken PWA.

What does offline-first actually mean in practice?

It means the app is designed to work from local data and treats the network as an enhancement, rather than assuming a connection and failing when it disappears. In practice that is a precached shell, local persistence for the data users need, clear indicators of what is stale, and a sync path for changes made while offline.

How does installability work, and what goes in the manifest?

The web app manifest is a JSON file declaring your app name, icons, start URL, display mode, and theme colours. With a manifest, a registered service worker, and HTTPS, browsers treat your site as installable and offer an add-to-home-screen path. Chromium browsers can show an install prompt you control; Safari requires the user to install manually from the share menu.

Can a PWA send push notifications on iOS?

Yes, but with real conditions attached. Web push works on iOS only once the user has installed the PWA to the home screen from the share menu — there is no push for a PWA opened in a browser tab, and no install prompt to nudge them. On Android and desktop, push works without that hurdle. If notifications are central to your product, plan for that gap.

Where does a PWA genuinely fall short compared with a native app?

iOS is the honest answer. Safari limits background execution, background sync is unavailable, storage can be evicted after a period of disuse, and install is a manual share-menu step most users never find. Deep hardware access, Bluetooth, and rich background location are also weaker or absent. If any of those are core to your product, we will tell you to build native.

Can a PWA be listed in the app stores?

On Android, yes — a PWA can be packaged as a Trusted Web Activity and published to Google Play as a regular listing over the same codebase. Apple does not accept a plain PWA wrapper on the App Store, so an iOS listing means a native shell or a cross-platform build. We can advise which route fits your distribution plans.

Can you convert our existing site into a PWA?

Yes, and it is one of our most common PWA requests. We audit what you have, add a manifest and icon set, introduce a service worker with a conservative caching strategy, then widen offline coverage route by route. It is incremental work — your site keeps shipping features while the PWA layer goes in behind it.

How do you handle Lighthouse and PWA installability criteria?

We treat the installability checks as a floor, not a goal: HTTPS, a valid manifest with the required icons, a registered service worker, and a responsive layout. Beyond that we audit Core Web Vitals, accessibility, and best practices in Lighthouse, because a green installability badge on a slow app helps nobody.

Does background sync work everywhere?

No. Background Sync lets a service worker retry a failed request once the connection returns, and it is supported in Chromium browsers. Safari does not support it, so on iOS we implement an in-app queue that persists locally and replays on the next launch. It is less seamless, but it means work done offline is never silently lost.

Hire PWA Developers

Build progressive web apps that load quickly, keep working when the network drops, and install to the home screen from a plain URL. We hand-pick every PWA developer and put them through real technical and trial rounds — so the person you hire already understands service workers, caching, and the platform limits that decide whether a PWA is the right call.

Why Dedicated

What You Get When You Hire Dedicated PWA Developers

When you hire dedicated PWA developers from OpenMalo, you get more than extra capacity — you get consistency, accountability, and the ability to scale without disruption. You're partnering with a team that has delivered 500+ products for clients across six countries, and that experience shapes how your project is run.

Your dedicated PWA developer is a seasoned engineer, not a stopgap contractor. They bring proven expertise across service worker architecture, caching strategy, web app manifests, push notifications, and performance, backed by the project management and quality assurance that keep delivery predictable. Whether you need a single specialist or a full embedded squad, they adopt your processes and treat your product as their own.

A PWA is easy to bolt on and easy to get wrong. A careless service worker serves stale pages for weeks, a badly scoped cache breaks logins, and an unversioned release strands users on an old build with no obvious way back. Our developers pair delivery speed with deliberate caching rules, versioned service worker updates, and tested offline behaviour — so what ships stays trustworthy.

Over 13+ years, and with a 5.0 rating on Clutch, we've helped organizations of every size turn complex requirements into reliable, scalable products. Hire a dedicated PWA developer who brings the discipline serious projects demand — and free your business from the overhead of full-time hiring.

Services

End-to-End PWA Development Services

Augment your engineering team or outsource the full build — we connect you with PWA developers, engineers, and architects who deliver from first commit to production-grade deployment.

Offline-First Applications

Apps that stay usable when the connection drops, with service worker caching, local persistence, and clear offline states — so field and transit users are not blocked by a dead signal.

Installable Web Apps

A correctly built web app manifest, icon set, and install flow, so your product can be added to the home screen and launched in standalone mode without an app-store submission.

Service Workers & Caching Strategy

Cache-first, network-first, and stale-while-revalidate rules chosen per route with Workbox, plus versioned updates and a safe kill switch — so releases reach users rather than sitting behind a stale cache.

Web Push Notifications

Permission flows, subscription handling, and server-side delivery that respect user choice, with graceful behaviour where a platform limits push to apps the user has actually installed.

Performance & Core Web Vitals

Bundle splitting, precaching of the app shell, image and font discipline, and render profiling — measured against Core Web Vitals on real mid-range hardware rather than a fast desktop.

PWA Conversion & Audits

Turn an existing site or SPA into an installable, offline-capable app incrementally, or audit a PWA that is failing installability checks and diagnose why users never see the prompt.

FAQ

Hire PWA Developers — Frequently Asked Questions

A service worker is a script the browser runs in the background, separate from your page. It sits between your app and the network, so it can serve cached responses, queue failed requests, and receive push messages. Without one you have no offline capability and no installability — it is the foundation every other PWA feature sits on.
