Flowise
Flowise is an open-source, low-code visual builder for LangChain-based LLM workflows and AI agents. Built on Node.js and TypeScript as a pnpm/Turbo monorepo, Flowise lets developers and non-developers compose chatflows, multi-agent agentflows, RAG pipelines, tools, and assistants on a drag-and-drop canvas, then expose them as REST APIs, embeddable chat widgets, or programmatic SDK calls. The project ships a self-hostable server, a React admin UI, a third-party node component library, an auto-generated Swagger UI, official TypeScript and Python SDKs, an embed widget, and a managed Flowise Cloud offering with metered prediction quotas. Flowise was acquired by Workday in 2025.
