Flowise

A low-code builder for LLM applications, letting you assemble chatflows, agents and retrieval pipelines by dragging nodes for models, prompts, tools and vector stores onto a canvas. It talks to whichever OpenAI-compatible endpoint you choose, supports tool and function calling, and exposes each flow as an API or an embeddable chat widget.

Product teams use it to prototype support bots, document assistants and internal copilots without hand-writing the whole orchestration layer.

Self-hosted, it runs against models you already pay for or local ones, keeps prompts and documents inside your network, and snapshots like any other service. It can be deployed with a single setup process.
