Project Summary

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

Builds are available for Windows, Mac, Linux, and as a Firefox extension

Project was originally sponsored by a Viatnamese site, Evolus, with code on googecode. That has not been updated since 2013, and new builds are occurring on an actively maintained fork on github.
