airflow vs wexflow
airflow has 47,350 GitHub stars, 18,299 forks, 1,831 open issues and last shipped yesterday. wexflow has 844 stars, 191 forks, 0 open issues and last shipped 5 days ago. airflow leads on adoption by 5,510% (47,350 vs 844 stars). airflow is written in Python under Apache-2.0; wexflow is written in C# under MIT. airflow has attracted 39% as many forks as stars, wexflow 23%. airflow was the more recently maintained of the two, and both are self-hostable with no licence fee. The two share 2 topic tags (automation, 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. 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…
