verifiedFreemiumAPIvanna.ai

Open-source and cloud SQL agent that lets non-technical users query company databases in natural language, with admin controls for teams.

What it does

Vanna is an open-source framework and hosted cloud service that turns natural-language questions into SQL queries against a company's databases, supporting multiple LLM providers (OpenAI, Anthropic, Gemini, Ollama) and databases (PostgreSQL, MySQL, Snowflake, BigQuery, and more). Paid tiers add hosted admin features like access control, observability, agent memory, and audit logging on top of the free open-source core.

How to use: You can use Vanna.AI by asking questions about your database in natural language. Vanna will then generate the SQL query for you. It can be integrated into Jupyter Notebooks, Slackbots, web apps, Streamlit apps, and other frontends.
