What our PWA development services cover
Web apps that behave like apps: installable, offline-tolerant, and fast on the worst device your users own.
Installable web apps
Full PWA packaging with manifests, service workers, and platform install prompts, so your app lands on the home screen without a store review in the loop.
- ✓Manifest and display modes
- ✓Install prompts and UI
- ✓App shell architecture
- ✓iOS and Android parity handling
Offline-first engineering
Service workers with deliberate caching strategies per resource type, plus background sync so user actions taken offline land safely when the network returns.
- ✓Workbox caching strategies
- ✓Background sync queues
- ✓Conflict resolution on reconnect
- ✓Offline UI states that are honest
Push and Re-engagement
Web push across platforms including iOS where supported, with permission UX that respects users enough to actually convert them into subscribers.
- ✓Cross-platform web push
- ✓Permission flow design
- ✓Segmented campaigns
- ✓Deep links into app state
Performance engineering
PWAs live or die on speed over bad networks. We engineer budgets for load, interactivity, and smoothness, then enforce them in CI rather than admiring them in audits.
- ✓Core Web Vitals budgets
- ✓Code splitting and prefetching
- ✓Critical-path rendering
- ✓Low-end device testing
PWA wraps of existing products
Turning an existing web product into an installable, offline-capable experience, and wrapping where a native shell still earns its place.
- ✓Service worker retrofit
- ✓Existing app offline audit
- ✓Store-listing wrappers where needed
- ✓Analytics parity
Migration from native to PWA
For products where two native codebases cost more than they return, we migrate to a PWA and keep the store presence via a thin wrapper if distribution requires it.
- ✓Feature parity audit
- ✓Native capability assessment
- ✓Phased migration plan
- ✓Store wrapper options
What every engagement includes
Every PWA project ships with the following, agreed in writing before the first sprint begins.
Discovery workshop
A structured workshop maps your goals, users, and constraints into a scoped PWA roadmap with a fixed written quote before any sprint starts.
Named senior team
You get named, senior engineers with CVs you can review, not a rotating bench. The people in the kickoff are the people who ship.
Sprint demos every two weeks
Working builds are demoed live each cycle with CI running on every merge, so progress is visible in software, not slideware.
100% source-code ownership
All PWA source, configurations, designs, and documentation transfer to you on delivery with no licensing strings or vendor lock-in.
60 days of post-launch support
Engineering time is on standby for two months after go-live to triage defects, tune performance, and stabilise the release at no extra cost.
12 months of free updates
Compatibility updates, security patches, and framework upgrades ship free for a full year after handover.
insight
Where a PWA is the right call
PWAs are strongest when reach and cost matter more than deep platform integration: content platforms, commerce, internal field tools, and products serving markets where storage-hungry native apps face resistance. One codebase, instant updates, and no store commission are real advantages when they match your distribution reality.
A PWA is usually built on the same web stack as the rest of your product, so our Next.js development services team handles most PWA builds. If you are weighing the PWA path against full native or cross-platform clients, our cross-platform app development page lays out the decision honestly.
The stack behind our PWA builds
What we use by default, and the honest constraints.
Core web platform
Service workers with Workbox precaching and runtime caching, web app manifests tuned per platform, and periodic background sync where the platform allows it.
Framework layer
Next.js or SvelteKit depending on the product, with app-shell rendering so repeat visits are near-instant even on poor connections.
Offline data
IndexedDB via Dexie or, for React products, TanStack Query persistence layers, with mutation queues and idempotency keys so offline actions replay safely.
Push and notifications
Web Push protocol with VAPID keys you own, platform-specific handling for iOS quirks, and a segmentation layer for campaign targeting.
Testing and quality
Lighthouse CI budgets failing the build on regression, Playwright tests run with service workers and offline simulation, and device-lab testing on low-end hardware.
AI features
On-device inference via WebGPU or WASM where it fits, cloud LLM features with graceful offline degradation, and caching of AI results to protect the experience on weak networks.
How a PWA project runs
Six stages, each proving something real before the next.
- 01
Discovery
We map user contexts (networks, devices, offline needs) and platform constraints honestly, including what iOS will and will not let a PWA do. Fixed written quote follows.
✓ step 01 complete - 02
Architecture
Caching strategy per resource type and offline data model are designed first, because retrofitting offline behaviour is the most expensive mistake in PWA work.
✓ step 02 complete - 03
Setup
App shell, service worker pipeline, and CI with Lighthouse budgets are scaffolded in week one, with installability verified on real devices early.
✓ step 03 complete - 04
Sprint delivery
Two-week sprints with demos on real phones, including throttled-network demos. Offline flows are tested as features, not as a pre-launch afterthought.
✓ step 04 complete - 05
Hardening and launch
Low-end device passes, storage quota audits, push delivery verified across platforms, and analytics confirming real-world performance against the budgets.
✓ step 05 complete - 06
Support and handover
60 days of included support, 12 months of free updates, and documentation covering the service worker logic so your team can evolve it confidently.
✓ step 06 complete

Why teams pick us for PWA work
PWAs fail through wishful thinking. We engineer for the worst case instead.
Offline is designed, not added
We design the offline data model and conflict rules before building screens. Retrofitting offline onto a network-dependent app is how most PWA projects quietly fail.
Honest about limits
We will tell you at discovery when iOS restrictions or hardware requirements (background location, Bluetooth depth) mean a native or cross-platform client is the better answer.
Performance as a gate
Lighthouse and Core Web Vitals budgets fail our CI on regression. Your PWA stays fast on the cheap Android your actual users hold, not just the office Wi-Fi.
AI-augmented delivery
AI tooling accelerates test generation and review on our PWA projects while senior engineers own the caching and sync architecture. Faster cycles, same rigour.
One codebase economics
For most products, a PWA plus a thin store wrapper beats maintaining two native codebases on both cost and iteration speed. We quantify that trade for your case.
Track record since 2010
9,000+ projects delivered across 25+ countries, including web platforms engineered for low-network environments.
