Wren AI
Canner
Open-source GenBI agent: ask in plain language, get governed SQL, charts, and dashboards.
An agentic GenBI platform from Canner that turns natural-language questions into governed SQL, charts, and live dashboards over 20+ databases and warehouses, from BigQuery and Snowflake to PostgreSQL and DuckDB. Its open-source core is a semantic 'context layer' (MDL) that grounds LLM-generated queries in business definitions instead of raw schemas. Runs self-hosted via Docker or as a managed cloud with RBAC and row/column-level security.
Worth knowing
In May 2026 Canner froze the AGPL GenBI app at v1-final and rebuilt Wren AI as an Apache-2.0 'open context layer' for agents.
