A faster, smarter web experience that works everywhere — even without internet.

At Webtech Nepal, we build Progressive Web Apps that close the gap between websites and native mobile apps. PWAs load instantly, work offline, send push notifications, and can be installed directly to a user’s home screen — all without requiring a trip to the App Store or Google Play. The result is a seamless, app-quality experience that lives on the web and performs like a native product.
Whether you’re a growing e-commerce brand looking to reduce cart abandonment, a service business wanting to reach mobile users faster, or an enterprise ready to replace a costly native app, we design and develop PWAs tailored to your specific goals. Our approach is rooted in modern web standards, performance engineering, and real user behavior — so every PWA we build doesn’t just impress technically, it drives measurable results for your business.

We provide tailored solutions built on creativity, precision, and trust - ensuring quality results and a smooth experience every step of the way.

Fields of Expertise

We deliver powerful Progressive Web Apps that help Nepali businesses perform, scale, and engage users across every device and connection.

Custom PWA Development

Fully bespoke Progressive Web Apps engineered around your brand, users, and business logic. We design and build from scratch using modern web APIs — Service Workers, Web App Manifests, and Cache Storage — delivering a native-grade experience without the complexity or cost of building separate iOS and Android apps.

Offline-First PWA Design

We architect apps that work reliably regardless of connectivity. Using intelligent caching strategies and background sync, your users get full functionality on slow networks or zero connection — critical for Nepal's diverse internet landscape and mobile-first audiences in areas with inconsistent data coverage.

PWA E-Commerce Development

High-converting online stores powered by PWA technology. Faster page loads, offline product browsing, add-to-homescreen prompts, and push notification reengagement all combine to reduce bounce rates, lower cart abandonment, and increase repeat purchases — giving your store a real competitive edge over standard mobile sites.

Push Notification Integration

Re-engage your audience without email or SMS. We integrate web push notifications that reach users directly on their device — even when the browser is closed — to deliver promotions, updates, reminders, and personalized alerts that drive traffic and conversions without the friction of native app installs.

Website-to-PWA Conversion

Already have a website? We upgrade existing WordPress, Laravel, or custom-built sites into fully functional PWAs — adding offline support, installability, and performance improvements without rebuilding from scratch. A cost-effective path to app-level engagement using your current content and infrastructure.

PWA Performance Optimization

Speed is not optional — it's a ranking signal and a conversion driver. We audit and optimize Core Web Vitals, Lighthouse scores, Time to Interactive, and First Contentful Paint to ensure your PWA loads in under two seconds on any device, improving both Google search rankings and user retention simultaneously.

PWA UI/UX Design

Interfaces built around how real people use mobile devices. We design touch-optimized layouts, fluid navigation, app-shell architecture, and gesture-driven interactions that feel native and intuitive — reducing friction at every step and keeping users engaged from first load to loyal return visit.

API & Backend Integration

Seamless connections between your PWA and the systems that power your business. From REST and GraphQL APIs to CRM integrations, payment gateways, and third-party platforms, we ensure your app communicates reliably — handling authentication, data sync, and error states gracefully in both online and offline modes.

PWA Analytics & Tracking

Data-driven insights for continuous improvement. We implement advanced analytics that track user behavior, offline usage patterns, push notification engagement, and install conversion rates — giving you the visibility to make smart decisions and optimize your PWA's performance long after launch.

PWA Security & HTTPS Implementation

Security is foundational to every PWA we build. Service Workers require HTTPS, and we ensure your app meets modern security standards — including secure data storage, content security policies, authentication best practices, and safe offline caching strategies that protect user data without compromising performance.

Accessible PWA Development

Progressive Web Apps built for everyone. We follow WCAG 2.1 AA accessibility guidelines — ensuring keyboard navigation, screen reader support, sufficient color contrast, and inclusive interaction patterns — so your app is usable by all audiences while meeting compliance expectations across regulated industries.

PWA Maintenance & Support

Ongoing care to keep your PWA fast, secure, and current. We provide regular Service Worker updates, dependency patches, performance monitoring, push notification management, and feature enhancements — so your app continues to deliver value as browser capabilities evolve and your business grows.

Our Process

Discovery & PWA Strategy

We begin by understanding your business objectives, target audience, existing tech stack, and the specific problems you need a PWA to solve. This phase defines the app's core features, offline requirements, performance benchmarks, and integration needs — giving every subsequent decision a clear strategic foundation aligned with real user behavior and your growth goals.

UI/UX Design & App Shell Architecture

We design intuitive, mobile-first interfaces and map out the App Shell model — the minimal HTML, CSS, and JavaScript needed to power the user interface. Every screen, interaction, and transition is crafted to feel native and responsive, with wireframes and prototypes validated against real user journeys before a single line of production code is written.

Frontend Development & Service Worker Engineering

Our developers build clean, performant frontend code alongside the Service Worker logic that powers offline functionality, background sync, and push notifications. We select the right caching strategy — cache-first, network-first, or stale-while-revalidate — for each resource type, ensuring optimal performance across varying network conditions without sacrificing data freshness.

Backend Integration & API Development

We connect your PWA to the data sources, APIs, and business logic it depends on — whether that's a Laravel backend, a WordPress CMS, a payment gateway, or a third-party service. We implement secure authentication, efficient data sync, and robust error handling so your app behaves reliably whether the user is online, offline, or moving between connections.

Performance Auditing & Optimization

Before launch, we run comprehensive audits using Lighthouse, WebPageTest, and real device testing to validate Core Web Vitals, PWA compliance, accessibility, and SEO scores. We optimize asset delivery, lazy loading, critical rendering paths, and Service Worker efficiency — targeting a perfect or near-perfect Lighthouse score that satisfies both users and search engines.

Cross-Device Testing & PWA Validation

We rigorously test across Android, iOS, and desktop browsers — validating installability, offline behavior, push notification delivery, and UI consistency on real devices and multiple screen sizes. Edge cases like intermittent connectivity, cache invalidation, and Service Worker updates are tested and resolved before any user encounters them in production.

Launch, Deployment & Ongoing Support

We manage the full deployment pipeline — HTTPS configuration, hosting setup, Service Worker versioning, and go-live monitoring. After launch, we provide ongoing maintenance to handle browser API updates, push notification management, performance regression alerts, and feature iterations — ensuring your PWA stays competitive and continues delivering value as your business evolves.
