A React UI kit for AI apps that lives in your repo, not node_modules

What it does

BoardUI is a React component collection built for AI-powered applications. It provides both the specialist pieces—chat streams, thinking indicators, agent logs, composers—and the standard dashboard furniture like tables, stat cards, and forms. Everything arrives as TypeScript source files that land directly in your codebase via a CLI, not as a black-box dependency. The repository doubles as a deployable Next.js app: its homepage is a working chat interface that streams responses from your own API key.

The interesting bit

The project treats “agent-native” as a first-class concern. It ships an MCP server so coding agents like Claude Code or Cursor can browse the catalog and install components on your behalf, and it includes AGENTS.md rules and llms.txt so the system knows how to build with its own tokens. That is a neat recursion: a UI kit designed to be consumed by the same kind of AI agents it helps you interface with.

Key highlights

• 62 free components as source: chat shells, data tables, charts, inputs, and accessibility primitives
• Bring-your-own-key chat starter with server-side key handling and support for OpenAI, Anthropic, Google, Groq, OpenRouter, Ollama, and others
• Built on React Aria Components and Tailwind CSS v4 with 400+ semantic tokens and no runtime CSS
• MCP server and agent rules let AI coding tools install and wire up components automatically
• Generated from upstream source; the repository does not accept pull requests

Caveats

• Repository is generated from BoardUI’s upstream source and takes no pull requests
• The built-in chat app stores history in the visitor’s browser with no database or backend persistence
• The deployed chat is open to anyone with your URL; spend caps at the provider are your only cost guardrail

Verdict

Worth a look if you are building an AI-facing product in React and want components you can actually edit without fighting a library’s internals. Skip it if you need a managed component service with community contributions or a backend-heavy chat application out of the box.
