Programmatically author, schedule and monitor data workflows in Python
Overview
What Apache Airflow does
Apache Airflow is an open-source platform for authoring, scheduling and monitoring workflows. It is the default answer to data pipeline orchestration in a large part of the industry: the thing that decides what runs, in what order, after what succeeded, and what to do when a step fails. Its defining choice is that pipelines are Python code rather than XML or a configuration DSL. A workflow is a Python file, so ordinary language features — loops, imports, datetime handling, conditionals — generate tasks dynamically. That makes pipelines testable and reviewable like any other code, and it makes them as complex as the person writing them. Airflow provides a web UI for monitoring runs and inspecting failures, prebuilt integrations with AWS, Google Cloud and Azure, and Jinja templating for parameterising runs. It is maintained by the Apache Software Foundation and developed openly through pull requests.
What people use it for
- Scheduling nightly ETL where step order and retries matter
- Coordinating machine learning training and evaluation runs
- Orchestrating dbt runs alongside extraction and loading
- Replacing a sprawl of cron jobs with dependencies and visible run history

The honest half
Where it falls short
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Apache Airflow.
- Self-hosting is genuinely heavy: scheduler, metadata database, workers and executor choice are a standing operational job
- Built for scheduled batch work, and a poor fit for event-driven or sub-minute latency pipelines
- Because DAGs are Python that the scheduler parses continuously, expensive top-level code in a DAG file slows the whole scheduler
- Local development and testing of DAGs is awkward compared with newer orchestrators designed with it in mind
Cross-shopped
What people choose instead of Apache Airflow
Each pairing was judged by two reviewers asking whether a buyer would genuinely weigh the two against each other. The ones that failed were deleted rather than published.
- Apache AirflowvsPrefect
Prefect: Python-native orchestration with a lighter operational footprint, aimed squarely at teams who found Airflow heavy to run
- Apache Airflowvsdbt
dbt: Handles the transformation step Airflow is frequently used to schedule, and the two are often run together rather than chosen between

Questions people ask
Each answer names the page it came from, so you can check it rather than take our word for it.
Is Apache Airflow free?
Yes. Airflow is open source under the Apache Software Foundation with no licence fee. Costs are the infrastructure to run it, or a managed service such as Google Cloud Composer or Amazon MWAA.
What language are Airflow workflows written in?
Python. A workflow is a Python file, so standard language features including loops and datetime handling can generate tasks dynamically, with no XML or command-line configuration.
Is Airflow suitable for real-time pipelines?
Not really. Airflow is designed for scheduled batch orchestration. Event-driven or sub-minute work is better served by a streaming platform such as Kafka or a purpose-built streaming engine.
What are the main alternatives to Airflow?
Dagster and Prefect are the two most commonly weighed against it, both newer and both designed around the local development and testing experience Airflow is criticised for.
