Both visualize LangChain. The split is ecosystem:
- Flowise — TypeScript, lighter deploy, richer node catalog
- Langflow — Python, picks up the latest LangChain components first
Python-heavy teams pick Langflow.
Strengths
- Python ecosystem — reuse existing LangChain components directly
- One-click export to Python code or API
- Acquired by DataStax — enterprise support available
- Rich Agent / Chain templates
Trade-offs
- Heavier deploy than TypeScript alternatives
- Heavy UI with many dependencies
Best for
- Data science / ML teams visualizing LangChain
- Shipping prototypes as runnable APIs
