Wren AI is an open-source Generative BI (GenBI) tool that enables data-driven teams to interact with their data using natural language. Users can chat with their databases to generate SQL queries, charts, spreadsheets, reports, and business intelligence dashboards. It supports custom LLM providers (e.g., via Ollama), integrates with Snowflake and DuckDB, and allows loading datasets directly from Hugging Face. Built with async pipelines using Haystack and Hamilton, it is designed for high concurrency, handling up to 1,500 concurrent users on modest hardware. With over 14,000 GitHub stars, it is a community-driven alternative to traditional BI tools.
