Flowise AI is an open-source, low-code visual builder for LLM applications that lets developers and technical users create complex AI workflows by connecting nodes in a drag-and-drop canvas. It supports all major LLM providers, vector databases, and AI tools — enabling rapid prototyping of chatbots, RAG pipelines, and multi-agent systems without writing boilerplate code. Startups and enterprise teams use Flowise AI to ship production AI applications significantly faster, with a self-hosted option that keeps sensitive data within their own infrastructure and eliminates per-query API costs.
