Vanna AI

★ 4/5 · Analytics

Open-source Python RAG framework enabling teams to train custom text-to-SQL assistants on their own database schema and query history.

Pros

Open-source with no vendor lock-in
supports multiple LLM providers (Anthropic, OpenAI, Gemini, Ollama)
hosted vector database option
audit logs and access control

Cons

Requires Python and technical expertise to set up
optional hosted features (Vanna Cloud) require separate subscription
not a turnkey SaaS solution

Cost

The open-source library is free to self-host; on Vanna Cloud, Explorer is $50/month for teams of two or three with 20 questions a day, Team is $500/month with 300 questions a day plus setup and same-day live support, and Enterprise is custom-priced with unlimited questions, on-premises deployment and SAML SSO; annual subscriptions take 20% off.

Verdict

Best for engineering teams wanting customizable, self-hosted text-to-SQL with full control over data and LLM choice.
