Marmo UI vs UXPin

Marmo UI pairs an open-source React design system with a hosted MCP server to help AI agents compose dashboards and apps using named @marmoui/ui components. The server provides live component APIs, composition patterns and generation rules; generated files pass through a review step that checks imports, props and compositions. The library includes more than 50 production-ready components and comes with Storybook and a Figma library. Developers install the React package with npm. The free plan includes documentation, the design tools and MIT-licensed core components, and allows unlimited projects, commercial use and no rate limits. Pro adds generation guided by a DESIGN.md file with brand details, plus composition patterns, Pro blocks, a hosted design-system site and priority support. It costs $9.99 per month, and a 14-day trial is listed. Integration instructions cover Claude Code, Codex, Cursor, Gemini CLI, Windsurf and other MCP clients. Generated code belongs to the user, uses the user’s own LLM tokens and stays in the user’s repository; it does not phone home.

UXPin is a design and prototyping platform for creating interactive prototypes with states, logic, conditional flows, variables, and dynamic content. It runs on the web and has UXPin apps for Mac and Windows, plus Mirror apps for iOS and Android. Core includes conditional logic, variables, and expressions, along with built-in coded libraries such as MUI, Tailwind UI, and Ant Design. Teams can share prototypes with unlimited viewers and commenters, and use public or team comments. Integrations include Slack, FullStory, Jira, Storybook, and Git, with a Figma plugin and Sketch import also listed. The Free plan allows two prototypes and 50 AI credits. Core costs $49 a month per seat when billed monthly, or $29 a month per seat billed yearly; Growth costs $69 a month per seat, or $40 a month per seat billed yearly. Core includes 200 monthly AI credits and seven-day version history, while Growth includes 500 monthly credits, 30-day history, roles and permissions, SSO, and 2FA. A 14-day trial is available.
