The Pencil Project

With the power of the underlying Mozilla Gecko engine, Pencil turns your excellent Firefox 3 browser into a sketching tool with just a 400-kilobyte installation package.

The Pencil Project's unique mission is to build a free and opensource tool for making diagrams and GUI prototyping that everyone can use.

 

Top features:

• Built-in stencils for diagraming and prototyping
• Multi-page document with background page
• On-screen text editing with rich-text supports
• PNG rasterizing
• Undo/redo supports
• Installing user-defined stencils
• Standard drawing operations: aligning, z-ordering, scaling, rotating...
• Cross-platforms
• Adding external objects
• And much more...

Pencil will always be free as it is released under the GPL version 2 and is available for virtually all platforms that Firefox 3 can run. The first version of Pencil is tested against GNU/Linux 2.6 with GTK+, Windows XP and Windows Vista.
