SARA
Open-source WhatsApp AI agent - 20 industry-specific brains
Open-source WhatsApp AI agent with 20 industry-specific brains. Self-host with Docker or use the cloud. AGPL-3.0. - Release v1.0.0 — First stable release · Alessandro114/sara. SARA is a self-hostable AI agent for WhatsApp that understands your industry. 20 verticals — restaurants, clinics, real estate, salons and more. Function calling with 30+ tools. RAG. Multi-language. Free LLM providers (Groq, Cerebras, SambaNova). Works out of the box with Docker Compose.
Hey PH! I'm Alessandro, and I built SARA because I was tired of seeing businesses pay thousands for chatbots that can only answer "What are your opening hours?"
SARA is different — it's an AI agent with function calling. When a customer asks "Table for 4 tonight?", SARA doesn't say "Please call us." It checks availability, books the table, flags allergens for the kitchen, and sends a WhatsApp confirmation. All autonomously.
The fun part: it runs on free LLM APIs. Groq → Cerebras → SambaNova → Mistral, with automatic failover. If one gets rate-limited, the next picks up. Total LLM cost: EUR 0/month.
I built it as part of SCALA, an AI operating system for SMBs. SARA is the first component I'm open-sourcing (AGPL-3.0).
There are 20 industry verticals already wired — restaurants, clinics, salons, real estate, gyms, automotive, and more. Each one has its own knowledge base, tools, and prompt engineering. You add your business data, not your architecture.
Try it:
```
git clone https://github.com/Alessandro114...
cd sara && cp .env.example .env
docker compose up -d
```
Would love your feedback. PRs for new verticals are especially welcome!
