A minimalist, high-performance digital whiteboard for the modern web.

Cicada is a lightweight sketching tool built for speed and elegance, it strips away the clutter to focus on what matters: your ideas.

Live Demo

• 🚀 Extreme Performance: Instant load times with zero-dependency architecture.
• 📦 Single-File Deployment: Optimized via Vite to a single, portable HTML file.
• 🔗 Smart Link Sharing: Entire drawings are compressed into ultra-short URLs using a custom binary codec—no database required.
• ✍️ Natural Feel: Smooth, pressure-simulated brush strokes and intelligent shape recognition (e.g., auto-snapping circles).
• 📱 Fully Responsive: Works seamlessly across Desktop, iPad, and Mobile.

• Custom Binary Codec: Uses Varints and ZigZag encoding to serialize canvas data into compact Base64 strings for URL sharing.
• RDP Path Simplification: Implements the Ramer-Douglas-Peucker algorithm to keep stroke data lean without losing detail.
• Vite + GitHub Actions: A modern CI/CD pipeline that automatically builds and deploys the modular source code into a minified, single-file production build.
