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.
Describe your idea in chat and Lovable turns it into a working app or website
Describe features in everyday language and the builder creates or edits the UI, logic, and structure of a full-stack web app.
Generate front ends, backend functions, and database-backed features rather than static mockups, so the result can actually run.
Ship your project to a shareable live URL, then point a custom domain at it when you are ready to launch.
Wire the app to external APIs and services, and add AI-powered functionality such as chat, search, or generation directly inside your product.
