SARA vs withOhm

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.

withOhm

withOhm is an OpenAI-compatible pipe that sits in front of your LLM calls and replays byte-identical requests from Redis instead of re-billing them — exact-match, not semantic, so every hit is provably the same request served again. BYOK: keep your own OpenAI/Anthropic/etc. keys. It also does purpose-bound, robots-aware public web fetch for agents that need to browse safely.
