Pencil

Pencil is an open-source graphics-design application for Linux. It is designed for creating diagrams and prototypes of graphical user interfaces. Its central purpose is to provide a free tool that people can use to develop and communicate visual ideas.

The software supports diagram work, allowing users to represent concepts, structures, or processes visually. It also supports GUI prototyping, which can help users plan the appearance and arrangement of an interface before it is implemented. These two uses make Pencil suitable for people who need to explore or explain visual designs.

Pencil is intended for everyone rather than a narrowly defined professional audience. Linux users can use it when they need an open-source application for diagramming or interface planning. Its placement in MirrorNest’s graphics-design category reflects this focus on creating and organizing visual concepts.

MirrorNest mirrors the official Pencil build directly on its own storage. The mirrored build is scanned for malware before it is published in the catalog. This distribution arrangement gives Linux users access to the official build through MirrorNest while retaining the software’s open-source licensing and graphics-design classification.
