Vanna AI review
A flexible foundation for developers building self-hosted, multi-user SQL assistants.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Vanna AI is an open-source Python framework for building AI agents that connect language models to databases. It turns natural-language questions into SQL, executes database tools, and supports multi-user data agents through role- and group-based access control. Developers can deploy it through web, API, or self-hosted environments, making it a fit for teams that want to shape the assistant around their own application, database, and permission model.
Pricing is structured around hosted usage and organizational support. Explorer costs $50 per month and includes 20 questions per day, an API, same-day email support, and admin features. Team costs $500 per month and raises the allowance to 300 questions per day, while adding setup support and same-day live support. Enterprise includes unlimited questions, on-premises deployment support, SAML SSO, an Admin API, and advanced integrations. The published plans make Vanna accessible for smaller deployments while reserving higher-volume and enterprise controls for larger implementations.
Its main strength is breadth across the model and database layers. Integrations include Anthropic, OpenAI, Azure OpenAI, Gemini, and Ollama, alongside SQLite, PostgreSQL, MySQL, MS SQL, Snowflake, and BigQuery. Tool memory can retain prior successful interactions, while streaming through FastAPI or Flask servers supports application-specific interfaces. Audit logging and observability add operational visibility, and interactive tables and charts extend the experience beyond generated SQL. Vanna is a strong choice for developers who need control and extensibility; teams seeking a ready-made, no-code SQL product may prefer a narrower application.
