About

What is wren-engine?

Wren Engine is an open-source context engine designed to provide AI agents with a semantic, governed, and agent-ready context layer for business data. It addresses the challenge of AI agents struggling with business context by allowing them to reason over definitions, metrics, relationships, permissions, and lineage. The engine enables agents to understand models instead of raw tables, use trusted metrics, follow relationships, and respect governance, transforming natural language into accurate, explainable data access. It supports over 15 data sources including Amazon S3, BigQuery, Snowflake, and PostgreSQL, and is built on Rust and Apache DataFusion. Wren Engine is particularly useful for agent builders creating natural-language analytics, AI copilots, and internal AI tools grounded in semantic models.

Best used for

Ideal for developers and data scientists who need to build AI agents capable of understanding complex business logic, accessing governed data, and generating accurate insights. Especially valuable for creating natural-language analytics tools and AI copilots that require deep business context beyond raw data access.

FAQs

What problem does Wren Engine solve for AI agents?

Wren Engine solves the problem of AI agents lacking business context. While agents can access data, they often don't understand definitions, metrics, relationships, or governance. Wren Engine provides this semantic layer, allowing agents to reason over business meaning rather than just raw tables.

What data sources does Wren Engine support?

Wren Engine supports over 15 modern data sources, including warehouses, databases, and file systems. Examples include Amazon S3, Apache Spark, BigQuery, ClickHouse, Databricks, DuckDB, Google Cloud Storage, MySQL, PostgreSQL, Redshift, SQL Server, Snowflake, and Trino.

How does Wren Engine compare to traditional data tools like catalogs or BI tools?

Unlike data catalogs that provide metadata or BI tools that offer curated metrics, Wren Engine focuses on providing an open context layer specifically designed for AI agents. It helps agents understand business meaning and produce correct queries, rather than just finding data or generating SQL.
