I got tired of spending hours dragging boxes in Lucidchart just to end up with a diagram that still looked like spaghetti. So I built something different.
InfraSketch turns natural language prompts into complete system architecture diagrams — in seconds.
How It Works
Describe what you're building — "Design a real-time analytics platform that handles 50k events per second"
Get a complete architecture — Not just boxes and arrows, but an actual system with proper data flows, caching layers, and failure handling
Refine through conversation — Click any component and ask questions: "How do we prevent data loss during failures?" The diagram updates as you discuss.
Export documentation — One click generates a full design doc with component details, scalability analysis, and security considerations
Key Features
- 🎯 AI-generated diagrams from plain English prompts
- 💬 Conversational refinement — ask questions, get instant visual feedback
- 📊 Component exploration — click any element to understand tradeoffs
- 📄 Automated documentation — export design docs ready to share
- ⚡ Fast iteration — seconds instead of hours
Who Is This For?
- Interview candidates prepping for system design rounds
- Engineers prototyping new architectures
- Tech leads exploring different approaches
- Students learning system design patterns
- Anyone who hates staring at blank canvases
Real Use Cases
I've used InfraSketch to design everything from simple URL shorteners to complex video streaming platforms. The AI understands common patterns like:
- Microservices architectures
- Event-driven systems
- Caching strategies
- Database scaling
- Load balancing
- Message queues
- CDN integration
- Real-time data pipelines
Why I Built This
Traditional diagramming tools force you to think in terms of shapes and connectors before thinking about the actual system. AI chatbots can explain concepts but won't build anything visual.
InfraSketch bridges that gap. You describe your system in natural language, and it builds with you — not just at you.
Try It Yourself
Head over to infrasketch.net and try the free tier. Start with one of the examples (Twitter Timeline, E-Commerce Checkout, URL Shortener) or describe your own system.
No credit card required. No drag-and-drop. Just describe what you want to build.
Built with: Claude AI (Anthropic), React, and lots of coffee ☕
