Wren AI

Wren AI OSS is an open-source "GenBI" (generative business intelligence) layer that converts natural-language questions into SQL queries, charts, and dashboards. It positions itself as an open context layer that sits between AI agents and data sources, enforcing shared definitions, access controls, and metric logic at query time via a semantic model (MDL, "Semantic Model as Code"). It's built to be LLM-agnostic and agent-agnostic, working with over 60 AI agents out of the box (including Claude), and supports 20+ data sources such as BigQuery, PostgreSQL, ClickHouse, and Amazon Redshift, plus dbt and metadata sync. The project ships weekly releases and has an active Discord community (1,700+ members). Paid options referenced include Enterprise Cloud, Self-hosted Enterprise Plus, and Embedded GenBI, but no specific costs are listed on this page.
