Show HN: Chatty – Open-source AI support engine with WooCommerce sync

Chatty is an MIT-licensed, self-hostable AI customer support engine positioned as an open-source alternative to Zendesk and Intercom, offering streaming chat, RAG over your own documents, lead capture, meeting booking, and human takeover. It supports seven messaging channels (WhatsApp, Messenger, Instagram, TikTok, Telegram, Twilio SMS, and inbound email), WooCommerce order and inventory sync, a LiveKit voice agent, and an 81-tool FastMCP server for agent-driven dashboard control. Deployment uses Docker Compose with managed Supabase for Auth, Postgres, Storage, and Realtime, and supports bring-your-own-key LLM providers including Gemini, OpenAI, Claude, and OpenRouter.
