What Vanna AI is
Vanna AI is an open-source framework for building user-aware agents that connect language models to databases. Agents can run SQL queries, generate charts, and use custom functions through tools. Tool Memory retains successful interactions and looks up earlier queries and tool-use patterns to adapt to similar questions. Configuration options include Anthropic, OpenAI, Azure OpenAI, Gemini, and Ollama language models; SQLite, PostgreSQL, MySQL, MS SQL, Snowflake, and BigQuery databases; and demo in-memory, ChromaDB, or Pinecone agent memory. FastAPI and Flask are listed as server choices, with a local FastAPI example. Vanna offers cloud hosting or self-hosting, and documentation describes user-specific access controls and tool access groups. The free plan is available; Explorer is $50 a month with 20 questions per day, while Team is $500 a month with 300. The security FAQ says its premium backend is in development/demo stage and lists limitations including in-memory storage, no encryption at rest, wide-open CORS, no rate limiting, and no authentication middleware.
