airflow has 47,301 GitHub stars, 18,202 forks, 1,831 open issues and last shipped yesterday. CocoIndex has 11,772 stars, 922 forks, 83 open issues and last shipped yesterday. airflow leads on adoption by 302% (47,301 vs 11,772 stars). airflow is written in Python under Apache-2.0; CocoIndex is written in Rust under Apache-2.0. airflow has attracted 38% as many forks as stars, CocoIndex 8%. airflow was the more recently maintained of the two, and both are self-hostable with no licence fee. The two share 2 topic tags (data-engineering, etl), 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 airflow
Apache Airflow Apache Airflow (or simply Airflow) is a platform to programmatically author, schedule, and monitor workflows.
