Overview

sunpeak provides a multi-platform runtime abstraction layer that helps you build components once and deploy them across different AI chat platforms like ChatGPT, Gemini, and Claude.

​
Why Multi-Platform?

Write Once, Deploy Everywhere

Build your component logic once, run it on multiple platforms without rewriting.

Consistent Developer Experience

Same React hooks and patterns across all platforms.

Future-Proof

Automatically support new platforms as they emerge.

Easy Migration

Switch platforms without major code changes.

​
React Hooks

sunpeak provides access to the entire platform runtime API via platform-agnostic React hooks. Here is an example component using some of these hooks: 
import { useTheme, useDisplayMode, useWidgetState } from 'sunpeak';

function MyComponentResource() {
  const theme = useTheme();                    // 'light' | 'dark'
  const displayMode = useDisplayMode();        // 'mobile' | 'tablet' | 'desktop'
  const [data, setData] = useWidgetState('key', defaultValue);

  return <div className={displayMode === 'mobile' ? 'w-full' : 'w-1/2'}>...</div>;
}

​
Widget API

One of these hooks, the useWidgetAPI, provides methods for interacting with the platform runtime, including calling MCP tools, sending messages, and controlling the platform display. 
import { useWidgetAPI } from 'sunpeak';

function MyComponentResource() {
  const api = useWidgetAPI();

  const handleAction = async () => {
    if (api) {
      // Call an MCP tool.
      const result = await api.callTool('my-tool', { arg: 'value' });

      // Send a follow-up message.
      await api.sendFollowUpMessage({ prompt: 'Continue the conversation' });

      // Open an external URL.
      await api.openExternal({ href: 'https://sunpeak.ai' });
    }
  };

  return <button onClick={handleAction}>Interact with Platform</button>;
}
