Vanna AI

Vanna (Vanna 2.0) is an open-source, multi-database, multi-turn conversational agent that lets users query databases using natural language instead of writing SQL. The company describes the goal as letting users "spend less time writing SQL and more time generating insights" on their data, making databases accessible to people regardless of their SQL expertise. It works with multiple LLM providers, including Anthropic, OpenAI, Gemini, and Ollama, and supports a range of databases such as SQLite, PostgreSQL, MySQL, Snowflake, and BigQuery. Optional hosted features add access control, observability, agent memory, file storage, and audit logs. It's available either self-hosted as open-source software or as a hosted cloud offering; the site references a dedicated pricing page but does not list specific plan costs.
