Curator's take

Flowise is the reference example of the visual-agent-builder category and still runs fine self-hosted, which is the only reason to reach for it today: the repo has been archived and development has stopped, so treat it as frozen. If you are starting new, go to sim or bytechef for the same drag-and-drop model with active maintenance, or to maxkb/claraverse if the RAG/chat-app angle matters more than the canvas. Existing Flowise deployments: plan the migration rather than extending them; the node ecosystem (LangChain/LlamaIndex bindings) will drift out of date quickly. Listed for lineage and for the many teams who still run it.
