Vanna.AI

Converts natural language questions into SQL queries for database interaction. Build AI agents that ship to production. User-scoped execution, rich UI components, and quota management built-in. Vanna.AI connects to any SQL database via Python, including Snowflake, Postgres, BigQuery, and more. The open-source version is free, with a paid hosted option for enterprise features. It supports offline LLMs like Ollama and local vector stores like ChromaDB. It stores only metadata locally, not sending database contents to LLMs. It supports OpenAI, Anthropic, Ollama, and others for flexible query generation. It’s designed for non-technical users to query via natural language.
