SARA vs Styx

SARA

SARA is a self-hosted WhatsApp AI agent that understands your industry. Pick a vertical — restaurant, clinic, real estate, salon — and get a domain-specific AI agent with real function calling tools (book tables, check allergens, schedule appointments). Not a chatbot wrapper. Stack: TypeScript, Groq/Cerebras/Mistral (free LLM APIs), pgvector RAG, Docker Compose.

Styx

A mac app so my coding agents can't deploy to prod without asking Run Claude Code, Codex and Gemini across a bunch of repos. Got tired of terminal chaos and agents having full access to my keys. Styx puts every project and agent in one window. Each agent works on its own branch. Nothing merges or deploys without my approval, and prod needs Touch ID. Keys stay on your machine.
