Vercel Open-Sources Chat SDK for Multi-Platform Bot Development

The SDK uses an adapter pattern where each platform has its own package handling webhook parsing, message formatting, and API calls. Rich UI elements like JSX cards and modals render natively on each platform, and built-in AI streaming support lets you pipe LLM responses directly into chat threads. State management runs on Redis for serverless production environments.

Build your chatbot logic once against the event-driven API, then add platform adapters for whichever channels you need — Slack, Teams, Discord, or all seven at once — without rewriting the core logic per platform.
