Efecto Design: Where Humans and Robots Design Together
A web design tool where humans and AI agents work side by side. Real code on the canvas — React, Tailwind, no translations. Here's what it is and how to start.
Who are we designing with, five years from now?
AI agents are already writing code, generating images, building apps. Designing is next. Not generating mockups from a prompt — actually placing elements, choosing layouts, tweaking spacing, iterating with you in real time.
That's Efecto Design.
What it is
A web-based design tool. Artboards, layers, text, images, buttons, frames. Flexbox layout with gap, padding, alignment. Smart guides that snap as you drag.
The difference: everything on the canvas is real code. React components. Tailwind CSS. Not a picture of a button — an actual button. Not a drawing of a layout — real flexbox.
This means no translation step. No designer-to-developer handoff where spacing gets lost and fonts don't match. The canvas is the code. And that opens up everything that comes next: publishing to GitHub, deploying to Vercel, adding interactions and animations — all directly from where you designed it.
The foundation for all of that is here now. The rest is coming.
Designing with AI agents
Efecto speaks MCP — the protocol that lets AI agents use tools directly. 39 of them. Create artboards, add elements, update styles, move things around, export images.
Connect Claude Code and it opens Efecto in your browser, designing in real time. You watch. You jump in. You tweak. You tell it what to change. Same canvas, same tools.
Pair programming, but for design.
Get started in 5 minutes
Three things: Node.js, Claude Code, and the Efecto MCP.
1. Install Node.js — grab it from nodejs.org
2. Install Claude Code
npm install -g @anthropic-ai/claude-code
3. Install the Efecto MCP
npx @efectoapp/mcp install
4. Run Claude Code
claude --dangerously-skip-permissions
Heads up: the
--dangerously-skip-permissionsflag lets Claude work without asking permission on every step. Great for getting a design going fast, but use it carefully — it means Claude can run commands freely. Remove the flag if you want to approve each action.
5. Design
Design a landing page for a coffee shop in Efecto
Claude opens Efecto in your browser and starts building. You iterate from there.
