Custom PWA Development
Installable, app-like web experiences built with React, Angular, or Vue plus Workbox service workers. Users get home-screen icons, push notifications, and sub-second repeat loads without an app store.
Web App
Progressive Web Apps
App-like experiences in the browser — no app store required.
PWAs combine the reach of the web with native app features: offline mode, push notifications, home screen install, and blazing performance.
Our Offerings
Progressive Web Apps Services We Provide
Website-to-PWA Conversion
We retrofit your existing site with a service worker, web app manifest, and offline caching strategy in as little as 3-4 weeks. Conversions keep your URL equity and SEO intact while adding native-feel UX.
Offline-First Architecture
IndexedDB storage, background sync, and conflict resolution so field teams keep working with zero connectivity. Data queues locally and syncs automatically the moment a connection returns.
Push Notification Engagement
Web push campaigns with segmentation, scheduling, and opt-in flows that respect browser permission best practices. PWA push re-engagement typically lifts return visits by 25-50% versus email alone.
PWA Performance Engineering
App-shell architecture, code splitting, and precaching tuned to hit Lighthouse PWA scores of 95+. Repeat visits load from cache in under 500 milliseconds on mid-range devices.
PWA for E-Commerce
Storefront PWAs with cached catalogs, one-tap checkout, and add-to-home-screen prompts at high-intent moments. Retailers using our PWAs report 20-35% higher mobile conversion than their previous responsive sites.

“We hired a dedicated team of five from Devlex to build our property management portal, and eighteen months later they still feel like our own employees. Releases ship every two weeks and platform uptime has held at 99.95%.”
“Devlex built an AI-powered quoting engine that cut our sales team's turnaround from two days to twenty minutes. They handled the LLM integration, the guardrails, and the training — and it actually works in production, not just in demos.”
“Our e-commerce replatform to a headless architecture was delivered GDPR-ready and PCI DSS compliant on the first audit pass. Page load times dropped 60% and conversion rose 18% in the first quarter after launch.”

E-commerce stores, media publishers, booking platforms, and field-service operations see the strongest returns because PWAs eliminate install friction and work on flaky networks. If most of your traffic is mobile web and you want app-like engagement without app store costs, a PWA is usually the right call.
Converting an existing site to a PWA takes 3-6 weeks; a full custom PWA built from scratch takes 2-4 months. Timelines depend mostly on offline requirements and the number of third-party integrations.
A custom PWA typically runs $15,000 to $50,000 — roughly 50-60% less than building separate iOS and Android native apps, since one codebase serves every platform. Site-to-PWA conversions start around $8,000.
Yes, full source code and IP rights transfer to you on final payment. You receive the Git repository, service worker configuration, build pipeline, and documentation so any team can maintain it.
Every PWA ships with 90 days of free bug fixes, then optional monthly maintenance covering browser compatibility updates, cache strategy tuning, and dependency patches. Browser vendors ship changes every 4-6 weeks, so proactive maintenance keeps your PWA performing.
Yes. Using Trusted Web Activity for Google Play and PWABuilder packaging for the Microsoft Store, we can publish your PWA as a store listing in 1-2 weeks. Apple's App Store requires a thin native wrapper, which we also build when needed.
