Vanna AI – Technical Overview
Vanna AI is an open-source (MIT license), self-hostable natural language-to-SQL framework founded in 2023.

- Multi-LLM provider: Swap or combine Anthropic, OpenAI, Gemini, or Ollama backends
- API available: Embed Vanna's SQL generation capabilities directly into your applications
- Self-hostable: Deploy entirely within your own infrastructure for data privacy and compliance
- Access control & observability: Built-in features for managing permissions and monitoring query activity
