Efecto

Efecto is a design tool where AI agents are first-class citizens. It provides familiar design features including artboards, layers, auto-layout, typography, and smart guides. The platform is built on JSX and Tailwind CSS, making it code-native from the ground up. It includes 66 MCP tools that allow AI agents to see your canvas, read your layers, and modify designs in real time. A full REST API with SSE event streaming gives programmatic access to every design primitive. Efecto also offers collaborative real-time multiplayer editing, a free stock photo library, and the ability to publish designs to live shareable URLs.
