Apache Airflow

Apache Airflow is an open source platform for programmatically authoring, scheduling, and monitoring workflows. It provides a single environment where users can create workflow definitions through programming, arrange workflows to run on a schedule, control when they execute, and observe their progress during operation. Its scope covers the workflow process from initial definition through scheduled execution and ongoing monitoring. Airflow is available under the Apache-2.0 license. It is intended for users who need to manage workflows through programmatic definitions rather than handling creation, scheduling, and monitoring separately. Apache Airflow can replace Zapier for automation needs that fit this model of programmed, scheduled, and monitored workflows. An important limitation is that Airflow centers on programmatic authoring: users need to define workflows through programming. This makes it a different approach for anyone looking for workflow automation that does not involve creating programmatic definitions.
