About Flowise
Developer Tools · Freemium · Open source · 36 upvotes · Launched week 27, 2026
Flowise is an open-source visual builder for LLM applications: chain models, vector stores, tools and memory as nodes, then expose the result as an API or embeddable chat widget. It suits prototyping and internal tools where writing framework code is overkill. Self-host free under Apache 2.0, or use the paid cloud.
