Overview
Flowise is an open-source visual LLM application orchestration tool with over 130,000 GitHub stars, one of the leaders in the open-source LLM orchestration space. Built on LangChain.js, it provides a drag-and-drop node editor for visually building RAG Q&A, Agent, Chatbot, and API workflows.
Core advantages: fully open-source (Apache 2.0) + self-deployable + 200+ nodes covering the full pipeline. Compared to Dify, it is more developer-oriented; compared to LangChain code, it has a lower barrier to entry, and is chosen by many teams as a "production-grade RAG/Agent visual foundation."
Key Features
- Drag-and-Drop Visual Orchestration: Build LLM applications with a node-based interface
- 200+ Nodes: Full coverage of LLMs, vector databases, Embeddings, tools, and Agents
- One-Click API Exposure: Workflows automatically generate REST APIs for embedding into your own products
- Multi-Model Support: OpenAI, Claude, Gemini, Ollama, and almost all mainstream models
- Chatflow + Agentflow: Supports both conversational RAG and multi-Agent orchestration
- Cloud Hosting Option: Flowise Cloud eliminates self-hosting
Use Cases
- Quickly build production-grade RAG for teams
- LangChain developers seeking visual tools
- Enterprise internal knowledge base bots
- Privacy-sensitive scenarios requiring self-deployment
- LLM prototyping and PoC validation
Pros
- Fully open-source Apache 2.0, commercially usable
- Node quantity and quality lead the open-source track
- Seamless integration with LangChain
- Extremely active community (130,000+ stars)
- Cloud hosting option reduces operational overhead
Pricing
Open-source version is completely free (Apache 2.0). Flowise Cloud: Starter $35/month, Pro $65/month, Business $225/month (more quotas, SSO, teams).
Summary
Flowise is one of the leaders in open-source visual LLM orchestration—the visual entry point for the LangChain ecosystem. It is the top choice for team self-deployment, with weaker commercial support that can be complemented by Dify / LangChain commercial versions.
