Open source framework for SQL agents your users can query
Reviewed by the the30top research team · Last reviewed 2026-10-27
Overview
Vanna started as an open source text-to-SQL library and its 2.0 release is an agent framework with user-scoped execution, rich UI components and quota management. It works with Anthropic, OpenAI, Gemini and Ollama models, and databases such as Postgres, MySQL, Snowflake and BigQuery, listing access control and audit logs. It is aimed at developers who build the agent into a product or internal tool, so non-technical teams will not get a finished analyst out of the box.
Our verdict
Vanna is a good foundation for developers who want control over models, data access and user experience. It is a framework first, so budget engineering time for it.
Best for
Engineering teams that want to build a governed SQL agent into their own product.
Avoid if
You want a ready-made analyst for non-technical staff with no engineering work.
Pros
- Open source with free choice of model
