Introduction
Apache Airflow has established itself as a standard for orchestrating workflows, especially for large-scale ETL (Extract, Transform, Load) jobs, machine learning pipelines, and complex data engineering projects. However, despite its popularity, Airflow isn’t always the best fit for every use case due to challenges like complexity in setup, limited support for modern cloud-native applications, and its dependency on Python-based DAG definitions. Fortunately, a range of alternatives has emerged that address these challenges, offering more flexibility, scalability, or ease of use. Below, we’ll take a deep dive into ten top alternatives to Apache Airflow in 2024, exploring their key features, strengths, and ideal use cases.
