Flowise
open-sourceAn open-source visual builder for LLM apps, chatflows, agents, and retrieval workflows.
Flowise is a visual development tool for building LLM workflows with nodes and connectors. It helps teams create chatbots, retrieval flows, agents, and API-backed assistants without writing every integration from scratch.
It is useful for developers and technical operators who want to prototype quickly while keeping a clear view of the workflow structure. Self-hosting makes it attractive for teams that need more control.
Complex production use still requires careful testing, observability, security review, and model evaluation.
