Extra Stencil Collections
- Android Lollipop by Nathanielw
- Bootstrap by Nathanielw
- Bootstrap Glyph Icons by Craig-Fisk
- Material Design Icons by Nathanielw
- Polymer Iron Icons by MercMobily
Additional collections are available on the Original Stencil Download Page.
- The Native UI Stencil Collection does not load or export correctly, you should avoid using this Stencil Collection for now(see #602).
- Dragging stencils onto the workspace does not work in newer version of
Firefox, either use Pale Moon, Xulrunner, an older version of Firefox, or
launch Pencil using
firefox --app /path/to/application.ini(see #802).
You will need version 4 or higher of
firefox to run Pencil as a
Firefox Extension. Linux users will need version 4 or higher of either
xulrunner, or version 25 or higher of
palemoon. The Windows installer and OS X archive
has everything you need built-in.
Windows, Linux, OS X & Firefox Packages are available for download from the Releases Page.
You can also install the Firefox Add-on from the Mozilla Add-on Repository.
To install the OS X package, unzip the archive and copy the
For specific Linux distributions:
- Arch Linux - Available in the AUR.
- Nix/NixOS - Run
nix-env -iA pencil. You'll need to be tracking Unstable.
- openSUSE - Available in the graphics repository.
- Ubuntu - A .deb is available on the Releases Page.
Pencil can be installed as Firefox Extension, instead of a standalone
application. To build the extension's
cd build ./build.sh xpi firefox Outputs/Pencil*.xpi
cd build ./build.sh linux xulrunner Outputs/Linux/application.ini || firefox --app Outputs/Linux/application.ini
Pencil-*-linux-pkg.tar.gz package will also be created. This contains
Pencil nested within the directory structure that most Linux distributions

entry & mimetype information. This can be used for creating
curl installed so you can pull the Windows XULRunner runtime and
NSIS to compile the installer.
cd build ./build.sh win32
This should place an installer
exe in the
curl installed to fetch the OS X XULRunner runtime.
cd build ./build.sh mac
This will create a
Pencil.app folder in
Outputs/Mac and a compressed
cd docs/ sudo pip install -r requirements.txt make html # Or if you want a PDF make latexpdf

You don't have to be a programmer to contribute! All feature requests & bug reports are appreciated.
- File Bugs and Feature Requests. If you are unsure how to do this, read "Writing Good Bug Reports".
- Reproduce Bugs – there are many issues which have not been confirmed since they were migrated from the original project. Try to reproduce the bug and state in a comment if you could reproduce it or not. State your operating system and Pencil version (example bug).
- Report Duplicate Bugs - lots of imported bugs are duplicates and simply add noise to the issue tracker. If you notice a duplicate issue, please leave a comment on the issue & mention the issue that you think it duplicates.
- Improve the Documentation. The files are in the
docsfolder and written in reStructuredText.
- Just spread the word :)
- Package Pencil for your distribution or OS.
- Create a Stencil Collection for your favorite UI framework or improve Pencil's default offering, as described in the Stencil Developer Documentation.
- There are many bugs to fix – if you could tackle one or two that would be
great! The most important bugs have a Critical label. The
starslabels are a heritage of the old google code repository: Many stars = many people interested in the bug or feature. You can also check the Milestones for issues to tackle.
- Commenting and documenting code to ease the programming for others – most of it is currently without comments and having them would help much.
If you make changes that affect users, please update
