- Code, infra, runbook — yours
PWA development servicesthat skip the app store entirely.
We don't treat progressive web app development as the fallback for teams that can't afford native. Done right, a PWA gives you push notifications, offline access, home screen installs, and instant updates — with no app store review, no 30% revenue cut, and one codebase instead of three.
- Installable
- Offline-first
- Push notifications
- SEO-indexable
Why Entalogics for PWAs
Four things every PWA
development project
actually needs.
Most PWAs we audit fail at the fundamentals — a service worker caching nothing useful, a manifest missing icons, no real offline strategy, push notifications untested on Safari. A progressive web app development company earns that name by getting the basics right first.
Performance01
Instant load, or the native app wins by default.
App shell cached in the service worker. Critical CSS inlined. Stale-while-revalidate for API data. A PWA that takes three seconds to load has already lost the argument it was built to win.
Architecture02
Service workers that cache with a strategy, not a guess.
Workbox configured per route — precache the shell, stale-while-revalidate for images, network-first for API calls. Not one blanket rule that serves stale data and confuses users.
State03
Offline-first, not offline-if-we-remember.
IndexedDB for structured local data, Background Sync for queued actions. The app holds up on a train and in a warehouse — not just on the demo WiFi it was tested on.
Type safety04
TypeScript strict, from the API to the service worker.
Typed cache strategies, typed push payloads, typed manifest config. When the API contract changes, the service worker fails the build instead of quietly serving broken cached data.
When PWA, when not
A PWA is a tool.
Not a native app replacement by default.
Progressive web app development is the right call more often than most teams assume — and the wrong one more often than PWA advocates admit. We'll tell you which side your product sits on before you commit budget.
BUILD A PWA WHEN
- Install friction is costing you conversions — every extra step between the URL and first use loses users
- SEO matters to your growth — native apps can't be indexed, a PWA ranks like any other web page
- Instant updates matter — push once, every user is on the new version immediately
- Budget is real — one codebase across mobile, desktop, and web at a fraction of native cost
CONSIDER NATIVE WHEN
- Deep hardware access is core — Bluetooth LE, ARKit, advanced camera control browser APIs don't expose
- iOS is your primary market and reliable background processing matters more than reach
- App Store presence is a genuine business requirement, not just a nice-to-have
- Performance-heavy workloads — gaming, AR, real-time video — where the browser becomes the bottleneck
WE SAY NO WHEN
- "A PWA so we never need a real app." Sometimes you do. We'll say so.
- "PWA for a graphics-heavy game." Wrong runtime for that job.
- "Offline, push, and payments live in two weeks." That ship has sailed.
What we build as PWAs
PWA development
services we deliver.
Six service types. Each one passes a real Lighthouse audit and behaves like an installed app — not a demo score on localhost.

Custom PWA development
Custom PWA developmentFrom concept to deployed app, we design and build progressive web apps on clean, typed architecture — caching strategy, manifest, and offline behaviour planned before the first line of UI code.

The playbook
PWA development patterns
we ship on repeat.
Patterns from real production progressive web app deployments — not Lighthouse demo scores that fall apart under real traffic.
P01
Workbox caching strategies per route.
Precache for the app shell. Stale-while-revalidate for images and assets. Network-first for API calls. Each route gets the strategy its data volatility actually calls for.
P02
A web app manifest done right.
Correct icon sizes for every platform, `display: standalone`, a themed splash screen. The install prompt shows up when it should — not never, not constantly.
P03
Push notifications that actually work on iOS.
Safari push has worked since iOS 16.4. We implement it with the right entitlements and the right timing, with a fallback for browsers that still don't support it.
P04
Background Sync for anything submitted offline.
A form submitted with no connection queues and sends the moment connectivity returns. No lost data, no "please try again" message.
P05
Lighthouse 100, measured in production.
Performance, accessibility, best practices, SEO — all green on the deployed URL under real conditions, not on localhost with an empty cache.
P06
Progressive enhancement, layer by layer.
Core functionality works without JavaScript. The service worker adds offline support. The manifest adds installability. Nothing breaks if one layer is missing.
Signature case
An e-commerce platform,
converted from native apps to a single PWA.
A B2C fashion retailer running separate iOS and Android native apps alongside a mobile website — three codebases, three teams, six-week release cycles. Consolidated into a single PWA with offline product browsing, push notifications, and instant checkout. Development cost dropped 68%. Mobile conversion increased 41%.
Before
3 codebases · 3 teams · 6-week release cycle · no SEO from native apps · $18k/mo maintenance
After
1 PWA codebase · 1 team · instant deploys · full SEO · $5.8k/mo maintenance
- Development cost−68%
- Mobile conversion+41%
- Time to deployinstant
- SEO traffic from mobile47k/mo

- W09+
Launch + handoff

FAQ
PWA development —
sharp questions, straight answers.
iOS support, native comparisons, cost, SEO — the questions we get on every PWA development call.Yes, with real caveats. Since iOS 16.4, Safari supports push notifications, home screen installs, and service workers — but background processing is still more limited than Android. We build for both platforms and handle the gaps with progressive enhancement.
For content-driven, transactional, and data-display products — often yes, at meaningfully lower cost. For apps needing deep hardware access, app store monetisation, or heavy rendering, native still wins. We'll tell you which one fits on the first call.
Yes — this is one of the biggest advantages progressive web app development has over native. A PWA is a real web page. Google indexes it, ranks it, and sends organic traffic to it the way it can't for anything living behind an app store.
Scope drives both numbers. A typical engagement runs 8–12 weeks end to end. We give you a fixed quote after the week-one audit — not a range that grows with every sprint.
Yes. Service worker, manifest, caching strategy, and push notifications layer onto an existing Next.js, Nuxt, or Vite app without a rewrite. Your app keeps shipping while we add each piece.
