airflow vs zerocode
airflow has 47,350 GitHub stars, 18,299 forks, 1,831 open issues and last shipped yesterday. zerocode has 1,016 stars, 455 forks, 128 open issues and last shipped 3 days ago. airflow leads on adoption by 4,560% (47,350 vs 1,016 stars). airflow is written in Python under Apache-2.0; zerocode is written in Java under Apache-2.0. airflow has attracted 39% as many forks as stars, zerocode 45%. airflow was the more recently maintained of the two, and both are self-hostable with no licence fee. The two share 1 topic tag (automation), 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. When workflows are defined as code, they become more maintainable, versionable, testable, and collaborative. Use Airflow to author workflows (Dags) that orchestrate tasks. The Airflow scheduler executes your tasks on an array of workers while following the specified dependencies. Rich command line utilities make performing complex surgeries on Dags a snap. The rich user interface makes it easy to visualize pipelines running in production, monitor progress, and troubleshoot issues when…
