FlowForge

The visual Mermaid editor that lives in VS Code

FlowForge is an open-source visual Mermaid editor for VS Code. Open a `.mmd` file and build diagrams on an infinite canvas: drag nodes, connect edges, and edit properties while Mermaid source stays in sync. Your diagrams remain plain, portable, Git-friendly Mermaid files — easy for teammates, Mermaid tools, and AI assistants to read and edit.
