FlowiseAI review

Verdict

FlowiseAI is the best low-code RAG builder, enabling users to construct and visualize complex chains through a drag-and-drop interface, greatly accelerating prototyping.

What customers praise

What customers criticise

While excellent for prototyping, it can be less suitable for complex, production systems that require fine-grained programmatic control, versioning, and testing.
