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.
Open-source control plane for orchestrating coding agents
Run Claude Code, Codex, Antigravity, OpenCode, Cursor and Grok sessions side by side in one workspace.
No resold tokens or quota caps — connect the credentials and plans you already pay for, and switch models mid-thread.
Manage branches, automate commits and pushes, and handle pull requests with inline diff review before accepting changes.
Open-source and MIT licensed, so you can run it on your own infrastructure and modify it for your team.
Offers an integrated AI-native code editor experience rather than a standalone multi-agent orchestration control plane.
