It's not even remotely close to a dead product. I work in platform-layer consulting where the services are quite often for customers who run ML and other data pipelines and Airflow is overwhelmingly the most popular DAG orchestration tool they're using.

I'm very curious what even gives you that impression. If you follow the link to their Github, it's got 38.5k stars, 14.6k forks, 3190 contributors, 92 releases, the most recent commit is from an hour ago. The most recent release is from last month.

I guess that Apache Airflow is more popular than the one linked by OP. Making a Google search for "airflow" in an incognito tab, looking at page 1, I see 5 results related to Apache Airflow, one result related to the OP, and a couple related to air conditioning (this was on Google Australia).

Apache Airflow is extremely popular and one of the most commonly used frameworks in data engineering. I guarantee you it is more popular than this Airflow by an order of magnitude or more.

It's in use in _a lot_ of data pipelines.

it’s extremely popular

Still, it was only one Google search away.

Lol! https://star-history.com/#Apache/airflow&Date

Is this a joke? I'd put Airflow almost on the level of postgres in terms of popularity (it's the most popular workflow manager).
