Vanna

What is Vanna?

Vanna is an open-source framework for building AI agents that respect who the user is. An agent is assembled from services for the language model, tools, storage, system prompts, middleware, observability and user authentication, so permissions and quotas can be enforced per user. Templates cover data analysis agents that query databases in natural language, document question answering, customer support, workflow automation and visualization with Plotly. The core is MIT licensed and can be self-hosted, and teams can later move to Vanna's managed cloud or an enterprise deployment without rewriting code. Paid plans on the pricing page are Explorer at $50 per month for 20 questions a day, Team at $500 per month for 300 questions a day, and custom Enterprise with unlimited questions, on-premise support and SAML SSO. Annual billing carries a 20% discount.

Use cases

• Ask a database questions in plain language
• Build an agent with per-user permissions
• Create document Q&A agents
• Generate charts and dashboards from data
• Automate multi-step workflows
• Add a support agent that tracks quotas

4. Test with your own data and permissions.
