Flowise: Open-Source Visual AI Agent Builder

Flowise: Build AI Agents Visually

Flowise is the open-source visual builder for AI agents and LLM orchestration. Drag-and-drop nodes for prompts, tools, models, and memory; chain them into agents and multi-agent crews. Where LangChain and friends require code, Flowise gives non-engineers and rapid-prototyping engineers a canvas they can ship from.

Flowise has joined Workday, but the OSS project remains active and broadly adopted — 12,400+ GitHub stars and counting. Use it for everything from a single chatbot with retrieval to multi-agent workflows that orchestrate Claude, GPT, Gemini, and other models on your own infrastructure.
