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.

Apty's browser extension for in-app guidance, onboarding and data-entry validation
Renders Apty's widget inside the host web app, listing all published workflows in a searchable panel so users can launch a guided flow on demand.
Runs background checks on form fields and highlights incorrect or missing data entry before the user submits a record.
Displays tooltips and broadcast announcements tied to specific UI elements or product changes, without requiring a new page or manual.
Lets users type keywords into the Player and pulls up the matching workflow or knowledge-center article directly.
