What is Vanna?

Vanna 2.0 is an open‑source AI framework that lets users query any relational or cloud data warehouse—such as SQLite, PostgreSQL, MySQL, Snowflake, or BigQuery—using natural language. The system translates spoken or typed questions into SQL and returns results, eliminating the need to manually write queries.

It supports multi‑turn conversations, allowing users to refine requests or ask follow‑up questions within the same session. Optional admin features include access control, real‑time observability, a hosted vector database for contextual memory, secure file storage, audit logs, and long‑term data retention.

Vanna can be deployed locally or in the cloud, and it works with popular LLM providers including Anthropic, OpenAI, Gemini, and Ollama. This setup is suitable for data analysts, business users, and developers who require quick, accurate insights from complex databases without deep SQL expertise.
