About Pencil
Pencil is a long-running GUI prototyping tool: drag widgets from bundled stencil collections, such as desktop, web and mobile controls, flowchart shapes and clip art, onto pages, link pages together and export the result as images, PDF or a clickable HTML mock-up.
Version 3 moved the app to Electron. The latest release, 3.1.1, dates from January 2023 and is offered on the official site as a universal macOS disk image.
