About Cube
Cube Core is an open source semantic layer for AI, BI, and embedded analytics. It lives in the data analytics and data engineering ecosystem for SQL warehouses, BI tools, applications, and AI agents. It lets teams define metrics, dimensions, joins, and access rules once in code, then expose them through SQL, REST, and GraphQL APIs. It is headless and ships no user interface.
About conduit
Conduit is an Apache 2.0 licenced data streaming tool written in Go that moves records between production data stores in real time, and it is aimed at data engineers who want Kafka Connect style pipelines without a JVM in the stack.
