Web Application Examples
Modern web applications that showcase what's possible with today's web technologies.
Last updated:
Web applications have reached a level of sophistication that rivals desktop software. From real-time collaboration to complex data visualisation, modern web apps deliver powerful functionality through the browser. These examples showcase different categories of web applications and the technologies that power them.
Linear
Developer ToolsThe fastest project management tool for software teams. Linear's web app is remarkably fast — instant page transitions, keyboard-first navigation, and real-time updates that feel native.
Vercel Dashboard
Developer ToolsVercel's deployment platform dashboard. Real-time build logs, deployment previews, and analytics — all in a clean, responsive web interface that works beautifully across devices.
Excalidraw
ProductivityOpen-source virtual whiteboard for sketching. Collaborative, real-time drawing with a hand-drawn aesthetic. The entire app runs in the browser with optional collaboration via WebSocket.
Retool
Developer ToolsLow-code platform for building internal tools. Drag-and-drop UI builder that connects to databases, APIs, and services. Shows how complex builder interfaces can work entirely in the browser.
Cal.com
ProductivityOpen-source scheduling platform (Calendly alternative). Clean, fast web app with complex scheduling logic, timezone handling, and multiple calendar integrations.
Frequently Asked Questions
Most modern web apps use: React or Next.js (frontend), TypeScript (type safety), Tailwind CSS (styling), WebSocket (real-time), and IndexedDB/Service Workers (offline). Backend: Node.js or Python with PostgreSQL. The trend is toward full-stack TypeScript with Next.js or tRPC for type-safe APIs.
Key techniques: optimistic UI updates (show changes before server confirms), prefetching (load data before user navigates), Service Workers (cache for offline/instant loads), virtual scrolling (render only visible items), and code splitting (load only what's needed). Linear and Notion demonstrate these patterns excellently.
