21st.dev
Browse 21st.dev for React components, templates, and shadcn themes—install via CLI or copy AI-ready prompts for Cursor and Claude Code.
Explore Subframe for visual UI design with real React components—drag-and-drop editing, design systems, deterministic code export, and MCP sync for Cursor and Claude.

Browse React component libraries and AI coding tools on Uwarp when a full design-to-code canvas is not the job.
Details below the decision summary—features, workflow, and scope notes.

Visual editor with real components
Drag, duplicate, and edit layers that map directly to React components—not abstract shapes detached from code.
Deterministic code export
Pages and components export as clean React and Tailwind without LLM misinterpreting your layout.
Design system sync
Build components with variants, props, and slots; sync them to your codebase via CLI as production source.
AI design assistance
Generate pages, themes, and components from prompts or images grounded in your system context.
Interactive prototypes
Share prototypes built from the same components used in exported code—confirm limits on free tier.
MCP and IDE workflows
Connect Cursor, Claude Code, and other MCP tools to export pages and iterate with codebase context.
Set up your system
Start from the prebuilt library or define custom components, tokens, and documentation in Subframe.
Design pages visually
Compose screens on a responsive canvas with auto layout and real component instances.
Sync or export code
Sync components via CLI to your repo and export pages through copy-paste or the MCP server.
Add business logic
Wire exported presentation code to APIs, state, and auth in your IDE—with or without AI assistants.
Product designers on React stacks
Design with components developers actually ship—reducing handoff friction and pixel drift.
Startup engineering teams
Move from screen design to production-ready UI faster without maintaining parallel Figma specs.
Design-system owners
Keep documentation, visual editing, and component source aligned in one tool.
