Design tools for coding agents, compared
Your coding agent gets a design team's library for free: 87 complete design systems, 420 design guides and 125 review rules, set up with one command.
Which should you choose?
- Choose Better Design if
- nobody hands your agent a design. It gets a ready-made design system, written guidance and review rules, and the guidance costs nothing on the free plan.
- Choose the Figma MCP server if
- your screens are already designed in Figma and the agent must match those frames, variables and components. Better Design does not read your Figma files from its hosted server.
- Choose the shadcn MCP server if
- you only need the agent to find and install shadcn/ui components, or components from your own registry. It is free, open source and has no paid plan.
- Adding Better Design isn't worth it if
- a designer already hands over finished Figma files and a team reviews every screen, or the project is a back-end tool with almost no interface.

Same scenario, priced
One developer, one month. A coding agent in Claude Code builds or changes interface code every day, and calls the design tool at least once a day.
Prices are per month on yearly billing where the vendor offers it, in US dollars before tax. The coding agent's own subscription is left out, because it is the same for every row. Read on 15 October 2026.

Adding or switching
What you install
Run npx -y better-design. It sets up 11 coding tools, and the install page lists the steps for the others.
What you keep
Keep the Figma MCP server and the shadcn MCP server installed. Better Design runs beside them, and its design systems install with the shadcn CLI from a shadcn registry.
What to test first
Ask the agent to rebuild one screen you already have, using a Better Design system. Then ask it to check that screen against the Better Design review rules, and compare both against your current version.
