Flowise
An open-source, drag-and-drop builder for LLM apps, chatbots and AI agents.
What is Flowise?
Flowise is an open-source, low-code tool for building applications with large language models. You connect nodes on a canvas, such as models, document loaders, vector stores and tools, to create chatbots, retrieval apps and agents, then deploy them via API or an embeddable widget.
Flowise makes popular LLM building blocks visual. Instead of writing all the code, you drag components onto a canvas and connect them, which is faster for prototyping and easier for teams to understand.
It supports retrieval-augmented generation, so chatbots can answer from your documents, as well as agent flows where models call tools and work through multi-step tasks. Many model providers and vector databases are supported.
Flowise can be self-hosted for full control or used as a hosted service. In 2025 Workday announced it was acquiring Flowise, and the open-source project continues to be available.
