Why Organizations are Exploring Estuary Alternatives

While Estuary Flow has gained traction as a real-time data integration platform, organizations are increasingly evaluating alternatives due to several limitations. Estuary's proprietary streaming infrastructure, built on Gazette/Flow rather than established platforms like Kafka (though it offers Kafka-compatible consumption via Dekaf), creates a learning curve that slows onboarding and requires teams to master unfamiliar concepts. Additionally, despite offering 150+ native connectors, gaps remain in legacy system support and batch processing capabilities that many enterprises require.

The unpredictable costs associated with Estuary's per-GB pricing model have also prompted organizations with fluctuating data volumes to seek more transparent pricing structures. As data integration requirements evolve, businesses need platforms that can handle both real-time streaming and efficient batch processing while maintaining cost predictability and ease of use.
