Langflow vs Flowise
You are picking between the two most popular open-source visual builders for LLM workflows. Both are self-hostable. The real choice is your runtime and how tightly you want to live next to LangChain.
Langflow
Open-source visual builder for LangChain-style agents and RAG flows — drag-and-drop, Python-native, self-hostable.

Flowise
Lightweight open-source visual builder for LLM agents and chatflows — Node.js-native, fast canvas, self-hostable.
Read review →Our take
For Python teams already using LangChain, Langflow. The mental model maps 1:1 to your code and the MIT license is clean. For JavaScript and TypeScript teams, Flowise. The canvas is faster, the embedded story is real, and you stay in your runtime. Both are solid prototypes; neither is the right pick if you need polished end-user agent products 鈥?Dify wins that.

Side-by-side
| Langflow | Flowise | |
|---|---|---|
| Runtime | Python (LangChain-native) | Node.js / TypeScript |
| License | MIT (true OSS) | Apache 2.0 (true OSS) |
| Canvas performance | Slower on large flows | Faster, lightweight |
| LangChain coupling | High (every node is a LangChain class) | Lower (own abstractions) |
| Custom components | Python classes | TypeScript classes |
| Embedded chat / SDK | API + iframe | Chat widget + REST API + SDK |
| Managed cloud | DataStax-hosted, mature | FlowiseAI Cloud, newer |
| Community size | Larger | Smaller but active |
| Best for | Python + LangChain shops | JS / TS shops |
