Azure Data Factory (ADF) is a powerful cloud-based data integration service, but there isn’t an open-source equivalent that provides the exact same functionality and seamless integration with Azure services. However, there are several open-source tools and frameworks that can be used as alternatives to build similar workflows and pipelines for data integration and ETL (Extract, Transform, Load). Here are some notable ones:

Key Considerations
While these tools offer similar functionalities, choosing the right one depends on:
• Your specific requirements (batch vs. streaming, cloud vs. on-premise)
• The level of coding or automation needed
• The ease of integration with existing data systems
