Quick Start

# Access at http://localhost:3000
# Drag nodes → connect → test → deploy as API

Why Non-Engineers Love It

LangChain requires Python expertise. Custom AI apps need backend knowledge:

No coding — build RAG apps by dragging nodes
Visual debugging — see data flow through each step
One-click API — deploy chatflows as REST endpoints
Embedded chat — add AI chat to any website with a snippet

A marketing team wanted an AI chatbot for their product docs. Instead of hiring a developer, they built it in Flowise in 1 hour — uploaded docs to a vector store, connected Claude, embedded the chat widget on their site.
