What is Flowise?
Flowise is an open-source, low-code tool that lets you build customized LLM orchestration flows using a visual drag-and-drop canvas. Under the hood, it wraps LangChain — so any LangChain concept (chains, agents, memory, vector stores) is available as a drag-and-drop node.
Key Features
- Visual Canvas — Each node represents a LangChain component. Connect them visually.
- 100+ Integrations — All major LLM providers, vector stores, document loaders.
- Chatbot Embed — One script tag embeds a chat widget on any website.
- API — Every flow gets a REST API endpoint.
- Marketplace — Community-contributed flow templates.

Flowise vs. Dify
Flowise is lighter and faster to run. Dify has more production-ready features (RAG pipeline, observability, team management). Start with Flowise if you just want to experiment; choose Dify for a production deployment.
