Flowise is an open-source low-code tool for building LLM applications using a drag-and-drop flow editor. Connect document loaders, vector stores, embedding models, LLMs, and output parsers visually to build RAG systems, chatbots, and AI agents without writing infrastructure code. The flow-based interface makes it accessible to developers who understand AI concepts but don't want to hand-write LangChain or LlamaIndex implementations from scratch. Embed chatbots in websites via an API endpoint, or use the flows programmatically in larger applications. For developers and technical teams building production AI applications with retrieval-augmented generation, custom knowledge bases, or multi-step AI pipelines, Flowise substantially reduces the boilerplate without reducing flexibility.
