Overview
Flowise is an open-source visual LLM application orchestration tool with over 130,000 stars on GitHub, making it a leader in the open-source LLM orchestration space. Built on LangChain.js, it offers a drag-and-drop node editor for visually building RAG Q&A, Agents, Chatbots, and API workflows.
Core advantages: Fully open-source (Apache 2.0) + Self-deployable + 200+ nodes covering the entire pipeline. Compared to Dify, it is more developer-tool oriented; compared to LangChain code version, it has a lower barrier to entry. Many teams choose it as a "production-grade RAG/Agent visual base." In 2025, Flowise was acquired by Workday, repositioning as an "Agentic systems development platform," adding core features like multi-agent orchestration (Agentflow), human-in-the-loop (HITL), and observability.
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: Automatically generate REST APIs from flows to embed in your own products
- Multi-Model Support: Support for OpenAI, Claude, Gemini, Ollama, and almost all mainstream models
- Agentflow Multi-Agent Orchestration: Supports multi-agent systems, coordinating multiple agents through workflow orchestration
- Chatflow Single-Agent Assistant: Single-agent system and chatbot supporting tool calls and knowledge retrieval (RAG)
- HITL Human-in-the-Loop: Allows humans to review agent-executed tasks in a feedback loop
- Observability: Complete execution tracing, supporting tools like Prometheus and OpenTelemetry
- Cloud Hosting Option: Flowise Cloud eliminates the need for self-hosting
Use Cases
- Teams quickly building production-grade RAG
- LangChain developers seeking visual tools
- Enterprise internal knowledge base chatbots
- Privacy-sensitive scenarios requiring self-deployment
- LLM prototyping and PoC validation
- Building multi-agent orchestration systems
Pros
- Fully open-source under Apache 2.0, commercially usable
- Leading node quantity and quality in the open-source space
- Seamless integration with LangChain
- Highly active community (130k+ stars)
- Cloud hosting option reduces operational overhead
- Acquired by Workday, enhancing enterprise-level support
Pricing
The 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 a leading open-source visual LLM orchestration tool—the visual entry point for the LangChain ecosystem. It is the preferred choice for teams needing self-deployment; for weaker commercial support, Dify or LangChain commercial versions can complement it. After its acquisition by Workday in 2025, it was repositioned as an Agentic systems development platform, adding enterprise features like Agentflow, HITL, and observability.
