The short version

  • Each has a real cost: Apache Airflow self-hosting is genuinely heavy: scheduler, metadata database, workers and executor choice are a standing operational job; Spring Cloud Gateway released under the Apache 2.0 license, free and open source with no commercial tier
  • They diverge on capability: Apache Airflow covers Pipelines as Python, Spring Cloud Gateway covers Routing.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

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

Spring Cloud Gateway

  • Released under the Apache 2.0 license, free and open source with no commercial tier

Answered from the vendors’ own pages

Apache Airflow: 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.

Spring Cloud Gateway: Is Spring Cloud Gateway free?

Yes, Spring Cloud Gateway is free and open-source software. It is part of the Spring ecosystem and available through GitHub repositories with open-source dependencies like spring-cloud-starter-gateway-server-webflux and spring-cloud-starter-gateway-server-webmvc.

Source
Apache Airflow: 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.

Spring Cloud Gateway: What enterprise support is available for Spring Cloud Gateway?

Tanzu Spring provides optional enterprise support including Day 0 access to security patches for organizations requiring guaranteed support, but specific pricing is not published on the Spring Cloud Gateway project page.

Source
Apache Airflow: 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.

Apache Airflow: 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.
