Progressive Web Apps (PWAs): offline-capable web apps, installable on mobile home screen, push notifications, background sync, works like native mobile app. Content-Rich Sites: news and media websites with dynamic content, blogs and publishing platforms, job portals with advanced filtering, real estate listings with map integration, educational platforms and learning management systems.

React.js vs traditional websites?
Understanding the difference helps you choose the right technology for your business. Traditional Websites (WordPress, PHP): Page-based architecture (every click loads new page from server), slower user experience (visible page reloads, loading spinners), limited interactivity (basic forms and links), SEO-friendly out of box (search engines read HTML easily), easier content management (WordPress admin, non-technical), lower development cost initially (LKR 60,000 - 100,000), suitable for: blogs, brochure sites, simple business sites, content-heavy sites with basic interactivity. React.js Single Page Applications: Component-based architecture (page updates without full reload), instant user experience (feels like desktop/mobile app, no loading between actions), highly interactive (complex forms, real-time updates, drag-drop, animations), SEO requires Next.js (we build all React apps with Next.js for SEO!), requires developer for content updates (unless we build CMS integration), higher development investment (LKR 80,000 - 300,000+), suitable for: web applications, dashboards, e-commerce, booking systems, portals, tools requiring lots of user interaction. Performance Comparison Example: Traditional site - click product filter, entire page reloads (2-3 seconds, visible loading). React SPA - click filter, products update instantly (<100ms, smooth animation). User completes task 5x faster! Real Metrics from Our Projects: React e-commerce vs traditional: 156% increase in time on site, 89% reduction in bounce rate, 43% increase in conversion rate, 4.2x more page views per session. When to Choose React: Your application requires frequent user interactions (filters, searches, updates), You want app-like experience on web, Real-time data updates needed (dashboards, booking systems, live feeds), You plan mobile app later (React Native reuses code), Complex UI requirements (multi-step forms, dynamic content, drag-drop), You're building customer portals, dashboards, or web apps, Performance and user experience are critical for your business. When to Choose Traditional: Simple informational website, Blog or content site primarily, Budget is very limited, Content changes frequently by non-technical team, SEO is only priority. Our Recommendation: Most modern businesses benefit from React's superior user experience and future scalability. We build React with Next.js (best of both worlds - app-like speed + SEO + performance). Let's discuss your specific needs! From LKR 80,000 for React apps.
