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.
Visual editing for React code, whether you wrote it or an AI did
Click any element in the live preview and Piny finds the component and file that renders it, so edits land in the right place in your source.
Adjust spacing, color, typography, flex and grid per breakpoint and state using your project's own theme, without hand-writing class strings.
Runs inside Claude Code and Codex workflows; Piny picks up your agent's edits and avoids overwriting them, and Target this element hands your agent exact file and line references.
Edit page text, images and local data such as product lists and JSON through forms rather than hunting through source files.
