About Flowise

Flowise is an open-source visual platform for building AI agents and LLM applications through a drag-and-drop interface. It supports multi-agent systems, retrieval-augmented generation, tool-calling chat assistants, and human-in-the-loop workflows — all assembled visually without writing orchestration code. Installation is a single npm command. Flowise offers both a cloud-hosted service with tiered pricing and full self-hosted deployment. The platform is Apache 2.0 licensed with over 52,000 GitHub stars. It is designed for developers and technical teams who want to build and iterate on agent workflows quickly using a visual interface rather than code-first abstractions.
