Dify vs Flowise vs Langflow

Short answer

Flowise is the fastest way to prototype a RAG chatbot on a canvas. Langflow is the same idea for teams already committed to LangChain. Dify is the heaviest and the most complete — workspaces, datasets, published apps with APIs — and the only one of the three that feels like a platform rather than a builder.

Prototype speed versus staying power

Flowise and Langflow win the first hour. Drag a loader, a splitter, an embedding model and a vector store onto a canvas, put an LLM node at the end, and there is a working RAG chatbot with an API and an embeddable widget. For proving an idea to someone who needs to see it, nothing here is faster.

Dify wins the sixth month. Datasets are managed rather than wired, prompts are versioned where non-developers can see them, apps are published with their own keys, and there is a notion of a workspace with members. The cost is a heavier stack and a steeper first day.

Licence conditions worth knowing before you build

Dify is Apache-2.0 with additional conditions: you may not run it as a multi-tenant service without permission, and the Dify branding must remain. Single-tenant deployments — one instance per customer — satisfy both, which is how every instance here is provisioned.

Flowise has no licence complication but does have a security one: versions before 3.0.6 carry a critical remote code execution advisory (CVE-2025-59528). An internet-facing Flowise on an older build is a genuine risk; we never deploy below the fixed release.

Langflow is MIT with nothing unusual attached.

When none of the three is the answer

If the job is “point it at our documents and let people ask questions”, a builder is overkill — AnythingLLM does that out of the box with citations and workspaces. If the source material is annual reports, scanned pages and complex tables, RAGFlow parses them properly instead of flattening everything to plain text.

Builders earn their keep when the logic is non-trivial: branching, tool calls, several data sources, conditional routing.

The verdict

Prove the idea on Flowise. Run it long-term on Dify if it becomes something the business depends on. Pick Langflow if your team already writes LangChain and wants a visual layer over the same components. And check whether AnythingLLM already does what you are about to build.

Questions

Questions

Can I export a Flowise flow into Dify?
No. The abstractions differ enough that moving means rebuilding, which is an argument for deciding what the thing is before you build it twice.
Is Dify free to use commercially?
Yes, with conditions: no unauthorised multi-tenant service, and the branding stays. Single-tenant instances comply.
Which needs the most memory?
Dify — API, worker, web, Postgres, Redis and a vector store. Plans start at 8 GB for that reason rather than selling a 2 GB tier that stalls.
