FlowiseAI/Flowise ? reverse-engineered prompt

I want to build a visual tool for creating custom AI agents and chatbots, basically a low-code platform for LLMs. The main feature should be a drag-and-drop canvas where users can connect different building blocks. For example, you could drag in a node for an OpenAI model, another for a document loader, and another for a specific prompt template, then wire them all together to create a RAG-based chat application.

The front-end should be a modern React app, and the back-end should be a Node.js server that executes the workflows. The whole thing should be built with TypeScript. The goal is to let people build and experiment with complex AI agentic workflows without having to write all the boilerplate code from scratch.
