Floneum
FreeVisual graph editor for building local LLM workflows
What is Floneum?
Floneum is an open-source graph editor for building workflows around large language models using drag-and-drop nodes. It targets developers and tinkerers who want to run language tasks locally.
Workflows are made from nodes such as text generation, structured text generation, embeddings, a vector database, web search, browser control and file reading or writing. The site lists 41 built-in plugins.
Plugins run in a sandboxed WebAssembly environment and only receive the resources they need. They can be written in any language that compiles to WebAssembly, and Rust has convenience wrappers.
