Flowise

platform active open-source

An open-source low-code platform for building LLM applications with a drag-and-drop interface. Flowise is built on top of LangChain and LlamaIndex, exposing their capabilities through visual nodes. It enables rapid prototyping of chatbots, agents, and RAG systems.

Implements

Concepts this tool claims to implement:

  • Agent Orchestration primary

    Visual agent builder using LangChain agents. Tool nodes for extending agent capabilities. Conversational agents with memory.

  • Workflow primary

    Node-based workflow canvas. Chain together LLM calls, retrievers, tools, and utilities. Export flows as API endpoints.

  • Retrieval-Augmented Generation primary

    Document loaders, text splitters, vector store nodes. Visual RAG pipeline construction. Supports multiple vector databases.

  • Tool Binding secondary

    Tool nodes wrapping LangChain tools. Custom tool creation. API tools for external service integration.

Integration Surfaces

  • Web UI (drag-and-drop)
  • REST API
  • Embed widget
  • Docker deployment
  • npm package

Notes

Flowise lowers the barrier to using LangChain/LlamaIndex. Good for prototyping and teams without deep Python expertise. Flows can be exported and customized in code. Active community with many example flows.
