Pencil
An open-source GUI prototyping tool that's available for ALL platforms.
Mermaid
Mermaid is a diagramming tool built on Mermaid.js, the open-source diagramming library. Diagrams are defined as text in Mermaid syntax, and the rendering engine determines the layout. When a process changes, updating the diagram is a text edit rather than a rebuild — the practical difference from drag-and-drop editors, where repositioning nodes is part of every revision.
