Thanks for the comment :) That's a good point. We considered using Airflow in the first place, but we decided not to. Because we had only a few number of developers and felt those tools were overkill for our use case. Also, we couldn't afford those tools' additional overheads such as operational costs or learning curves. We just wanted a better Cron that can be easily installed and operated and is capable of visualizing and running DAGs.
