What Vanna is

Vanna is an open source framework for building SQL agents. It lets people ask database questions in natural language and get answers through generated SQL, and version 2 adds user-scoped execution, rich UI components and quota management so agents can be put in front of real users.

It works with any language model provider and database combination.

What you can do it

• Build a chat interface over your database
• Let non-specialists query data
• Keep queries within each user's permissions
• Cap usage with quotas

Who it is for

• Data and platform teams
• Companies opening data access internally

What to watch out for

• Generated SQL runs against real data, so read-only roles and row-level permissions are essential
• A natural language answer can be confidently wrong; show the SQL and let users check it
• Model providers receive schema and question text unless you self-host
• Confirm current provider and database support
