Open-source frontend stack for building AI agents and copilots inside your own product
Ship a working copilot UI in minutes with drop-in components for React, Angular, Vue, iOS, and Android, or go fully headless for total control over rendering.
A general-purpose bi-directional link between your app and any agent backend, with integrations for the OpenAI Agents SDK, Claude Agent SDK, LangChain, Google ADK, AWS Strands, Mastra, and many more.
Agents return real UI — charts, forms, tables, and approval prompts rendered with your own design system on the same screen the user is already working in.
Let agents read and write application state, call your frontend functions, and pause for human approval before sensitive actions are executed.
Give your coding agent real design judgment
A structured skill set that agents load to make typographic, layout, spacing, and color decisions with design intent rather than defaults.
Identifies recurring AI-generated UI clichés such as chip overload, card-in-card nesting, weak hierarchy, and vague calls to action.
Helps the agent stay consistent with the tokens, components, and conventions of your existing design system.
Bakes in contrast, focus, semantic structure, and responsive behavior so built interfaces hold up across devices and audiences.
Provides a full AI-native code editor experience, but requires manual prompt rules or extensions to enforce design discipline.
