Progressive Web App Development
Installable, offline-first web apps with mobile DNA
We build Progressive Web Apps that combine the reach of the web with the feel of a native app — installable to home screen, offline-capable, push-notification-ready and SEO-friendly. The most cost-effective path to a mobile presence.
Installable, offline-capable web — without the App Store tax
Progressive Web Apps have grown up. With service workers, Web Push, native install prompts and modern browser APIs, a PWA can deliver 90% of the native experience while keeping the reach, indexability and zero-distribution-friction of the web. For many B2B tools, content products and emerging-market consumer apps, it's the right answer.
We ship PWAs that score 95+ on Lighthouse, install on iOS, Android and desktop, work offline through service workers and deliver push notifications via Web Push. The same codebase serves SEO traffic, paid acquisition and your loyal installed base — without a separate native team.
Why this engineering choice matters
One product, every device
iOS, Android, desktop, low-end Android tablets — one codebase covers them all with adaptive layouts and platform-aware install prompts.
Performance you can measure
Lighthouse 95+ on Performance, Accessibility, Best Practices and SEO — enforced as CI gates on every PR.
Offline-first via service workers
Workbox-driven caching strategies, background sync and IndexedDB make the product useful when the network isn't.
Web Push notifications
Real push channels on Android, desktop and (with iOS 16.4+) iOS — for re-engagement without an app.
Native install + share targets
Add-to-home-screen on iOS and Android, file-handling, share targets and protocol handlers — feels native, installs in 2 taps.
One deploy, no store gatekeeping
Push to production in minutes, not weeks — no App Store review queue, no Play Store policy surprises.
Core App Capabilities
Installable PWAs for iOS, Android and desktop
Web App Manifest, adaptive icons, splash screens and platform-aware install prompts.
Offline-first architecture
Workbox runtime and pre-caching, background sync, IndexedDB for structured offline data.
Web Push and in-app notifications
VAPID-based Web Push, in-app toast / alert systems and engagement scheduling.
Modern web authentication
Passkeys (WebAuthn), federated OIDC, secure session storage and CSP-hardened delivery.
Headless commerce and CMS integration
Shopify Hydrogen, Sanity, Contentful, Strapi or custom backends consumed through GraphQL or REST.
Edge delivery and observability
CDN + edge functions for sub-100ms TTFB, with real-user monitoring exported to your analytics stack.
Ideal Business Use Cases
Startups validating ideas, content publishers, e-commerce stores wanting instant install, and businesses that want full SEO visibility while still feeling like an app.

Industries we deliver this to
How we deliver this engagement
Performance budget definition
Per-route LCP, INP and CLS budgets — enforced as CI gates so regressions never reach production.
Architecture & rendering strategy
Next.js, Remix, SvelteKit or Astro — chosen after a written trade-off analysis around SSR/SSG/ISR needs.
Implementation with edge in mind
Edge functions for sub-100ms TTFB, image optimisation, font subsetting and route-level code splitting.
Offline & install integration
Workbox service worker, Web App Manifest, install prompts, Web Push and background sync.
Quality gates
Lighthouse 95+ gates, Playwright end-to-end, real-device testing on mid-range Android and old iOS.
Operate & evolve
Real-user monitoring, error budgets, weekly performance reviews and quarterly browser-readiness audits.
Security posture
- Strict Content-Security-Policy with nonces and report-only staging
- Passkeys (WebAuthn) for phishing-resistant auth
- Secure session storage with httpOnly + SameSite cookies
- Subresource Integrity (SRI) for third-party scripts
- Cross-Origin-Opener-Policy and CORP hardening
- Regular OWASP Top 10 review and dependency scanning
Scalability engineering
- Edge-cached static and dynamic content via CDN
- Serverless edge functions for personalised SSR
- Multi-region origin failover
- Image optimisation at the edge (AVIF/WebP)
- Feature flags for safe progressive rollout
- Real-user monitoring with per-route performance budgets
