Caja is a design tool built for the AI era. Your browser engine is the canvas, no middleware, no translation layers. Design by hand, delegate to AI, or both.
No middle man
Your designs are the implementation. Real HTML, real CSS, real Tailwind. No rebuild, no translation layer.
Built for you and agents
Design by hand or connect Claude, Cursor, or any AI agent via MCP. You and agents are both first-class citizens.
Familiar yet new
Everything on the web is a box. A layout model you already know, powered by the stack you already use.
Free and open source
Native macOS app built with Tauri. No subscriptions, no cloud dependency. Your files, your rules.
