Dagster: Orchestration built around data assets and local testability, the two things Airflow users most often complain about

Programmatically author, schedule and monitor data workflows in Python
As of 29 August 2026, Apache Airflow is free to use. The open-source standard for data pipeline orchestration. Softwr lists it under Databases. Apache Airflow is made by Apache Software Foundation, launched in 2015, available on Linux, Self-hosted.
Overview
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.
The honest half
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.
Cross-shopped
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.

Prefect: Python-native orchestration with a lighter operational footprint, aimed squarely at teams who found Airflow heavy to run

Extensible operators
Write custom operators when no provider package fits
Answered, with sources
Each answer names the page it came from, so you can check it rather than take our word for it.
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.
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.
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.
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.

Softwr does not host reviews and shows no star rating for Apache Airflow, because a rating we did not collect is not ours to publish. What is here is the pricing and platform detail from the vendor’s own pages, limitations we could state concretely, and alternatives a reviewer confirmed people weigh against it.
