In their own words
Vanna AI
Vanna AI is an open-source, user-aware agent framework that connects language models to databases. Agents can run SQL queries, generate charts, and call custom functionality through tools. Tool Memory records successful interactions and searches earlier queries and tool-use patterns when handling similar questions. Listed language-model options include Anthropic, OpenAI, Azure OpenAI, Gemini, and Ollama. Database integrations include SQLite, PostgreSQL, MySQL, MS SQL, Snowflake, and BigQuery; memory options include demo in-memory storage, ChromaDB, and Pinecone. Vanna can run through Vanna Cloud or by self-hosting, with FastAPI and Flask server choices. Documentation describes user-specific access controls and tool access groups. Explorer costs $50 a month for 20 questions per day, while Team costs $500 a month for 300. Enterprise pricing is custom, with unlimited questions and listed enterprise features. The security FAQ describes the premium backend as in development/demo stage and lists current limitations.
Wren AI
Wren AI is a governed data agent for business questions, dashboard creation, and AI-agent data queries over MCP. Its MDL context layer models metrics, relationships, calculations, and approved data, and can be version controlled. The agent plans multi-step analysis, queries data, builds charts, and uses reusable Skills, shared Knowledge, and private project-scoped Memory. Users can describe dashboards, reports, or custom views in plain English, refine them conversationally, and save them as reusable Artifacts. Data connections include Snowflake, BigQuery, Databricks, Redshift, PostgreSQL, MySQL, SQL Server, Oracle, ClickHouse, Trino, Starburst, Athena, and CSV. Claude, ChatGPT, Claude Code, and compatible MCP clients can call Wren AI as a sub-agent. Deployment options include managed or private cloud, self-hosting, and air-gapped setups. The maker describes OIDC identity, project isolation, supported row- or column-level query controls, and audit logs, and labels its cloud SOC 2. Essential Cloud costs $179 a month, billed annually; a free plan is also listed.
