Open-source SQL agent that converts natural language questions into SQL queries across major databases.
About
Vanna.ai is a text-to-SQL tool that lets users ask questions about their data in plain English and receive accurate SQL queries and results in return. It connects to databases including PostgreSQL, MySQL, Snowflake, BigQuery, and SQLite, and supports multiple LLM backends such as OpenAI, Anthropic, Gemini, and Ollama. The core library is open source and self-hostable at no cost. Vanna Cloud adds a managed hosting layer with an admin dashboard, access controls, audit logs, and observability features. Enterprise plans with custom deployments and compliance options are available on request.
