Cube has 20,857 GitHub stars, 2,138 forks, 1,185 open issues and last shipped yesterday. CloudQuery has 6,520 stars, 558 forks, 166 open issues and last shipped yesterday. Cube leads on adoption by 220% (20,857 vs 6,520 stars). Cube is written in Rust under a custom or non-standard licence; CloudQuery is written in Go under MPL-2.0. Cube has attracted 10% as many forks as stars, CloudQuery 9%. Cube was the more recently maintained of the two, and both are self-hostable with no licence fee. The two share 1 topic tag (bigquery), so they are genuine substitutes rather than adjacent tools.
Two open source projects, one decision. Both are free and self-hostable — the differences are community size, license terms, language stack and release pace.

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 CloudQuery
CloudQuery is an open source, Go based cloud asset inventory and ELT tool, licensed under MPL 2.0, that syncs metadata from AWS, Azure, GCP, and more than 70 cloud and SaaS sources into a data warehouse so platform, security, and FinOps teams can query it with SQL.
