Flowise pros and cons

The drag-and-drop canvas dramatically lowers the barrier to building RAG pipelines and multi-agent systems, letting teams prototype working AI applications without hand-writing orchestration code.
As an open-source project
Flowise offers full transparency and infrastructure control, with the option to self-host on AWS, Azure, or GCP for data-sensitive environments.
Built on the LangChain ecosystem, it supports a wide range of language models, vector stores, and tools, giving builders flexibility rather than locking them into a single provider.
Real total cost is hard to predict: the subscription is only the starting point, and LLM tokens, vector databases, and hosting can add substantially without published overage pricing.
Despite the visual interface, building reliable production agents still involves real complexity, and users without ML or backend experience will hit a meaningful learning curve.
Self-hosting delivers control but shifts the burden of deployment, scaling, security, and maintenance onto your own team.

Free and open source
Enterprise features: type safety, DI, telemetry
Multi-language (C#, Python, Java)
Strategic focus shifting to Microsoft Agent Framework
Concepts like planners have changed across versions
Python support historically trailed .NET
