Flowise

Flowise is an open-source, low-code tool for building LLM applications by connecting nodes on a visual canvas. It gives you a hands-on way to assemble AI apps without starting from raw code.

What it does

In Flowise you drag and connect nodes representing language models, data sources and tools to create chatbots, agents and RAG pipelines. Because it is open source and self-hostable, you keep control of your setup and can run it on your own infrastructure. Finished flows can be exposed as APIs and dropped into your own applications.

Who it’s for

Flowise appeals to developers, makers and teams who want to prototype LLM apps quickly with a visual approach. The open-source model and community are real advantages, though self-hosting takes some technical comfort and large flows benefit from careful organization. It is free to use — check the website for any premium or hosted options.
