A UI and UX review on every screen your agent builds.
Better Design is an MCP server for coding agents. When the agent finishes a screen, it checks the design, the behavior, the words and the spacing, then fixes the serious problems before it shows you.

What the review checks
Checked before you see it
After the agent builds or changes a screen, the MCP asks it to run the review and fix every critical and serious finding before it shows you the result.
UI principles
Layout, type, color and depth. The agent reads the principle before it styles the screen, then checks the result against it.
UX principles
Flows, forms, errors and onboarding. The review looks at how the screen behaves, not only at how it looks.
Review rules
Accessibility checks, plus the patterns that make a screen look generated, such as decorative gradients and left-stripe callout boxes.
Copy clarity
The comprehension check reads the screen's own words. It flags insider terms, long sentences and buttons like Continue that hide what happens next.
Measured spacing
The spacing check measures the rendered page at desktop and phone widths, so gaps and alignment come from the page, not a guess from a screenshot.
Questions
When does the review run?
After the agent builds or changes a screen. The MCP tells the agent to run the review tools before it presents the result, and to fix every critical and serious finding first.
Where do the rules come from?
They are the same UI principles, UX principles and review rules published on this site, so you can read every check the agent runs.
How is this different from GitHub PR reviews?
This review runs inside your coding agent while it builds. GitHub PR reviews run on the pull request, and check the diff and the preview before merge.
Does Better Design replace a designer or Figma?
No. People still own product and design judgment, and Figma still supports exploration and collaboration. Better Design carries the approved decisions into what the agent builds and reviews.
Which coding agents does it work with?
Better Design is an MCP server. It installs in Claude Code, Cursor, Codex, VS Code, ChatGPT, Devin, Antigravity, OpenCode and Cline.
Where does the output live?
In your repository. The design system installs as editable component source and values, so the team keeps control and can keep building from the same foundation.
