I built a real-time cryptocurrency dashboard using AI agent mode (mostly Claude Opus 4.5) in less than 2 days.
Live demo: https://krypto.markets
Features:
- Real-time prices via Binance WebSocket
- TradingView-style candlestick charts (1m to 1D timeframes)
- Drag-and-drop layout with save/sync
- Price alerts with browser notifications
- Command palette with CLI commands (⌘K to add coins, set alerts, etc.)
- Fully responsive
Tech: Next.js 16 (App Router), React 19, TypeScript, Tailwind CSS 4, Zustand, Lightweight Charts, Drizzle + Turso, Better Auth
I wanted to test how far I could push AI-driven development. Claude handled WebSocket integration, responsive design, chart implementation, auth, and debugging. My role was mostly directing, reviewing, and making design decisions.
The result surprised me. What I expected to take weeks was functional in under 48 hours. Not everything was perfect on the first try, but the iteration speed was remarkable.
Curious to hear HN's thoughts on AI-driven development and the project itself.
