Floneum is a workflow engine that allows users to visually create AI-powered workflows. It uses WebAssembly to securely load plugins in a sandboxed environment and provides them with access to only the resources they need. Plugins can be written in any language that can be compiled to WebAssembly, including Rust, C, Java, or Go. Users can try Floneum today by downloading the guide, joining the Discord community, or accessing the source code.
