Keep in mind that OpenPonk is still in early development and contains many bugs and missing features.

We are also performing a major overhaul of many parts (such as working on a full UML 2.5 metamodel, creating user documentation, and more) and we plan to do a release in late summer 2017.

Alpha is a semi-stable version, but possibly outdated compared to bleeding edge.

Bleeding edge is the very latest version that passed CI, but is still possibly broken.

Direct installation

To install OpenPonk with all default plugins to an existing image, use the following snippet:

Metacello new
    baseline: 'OpenPonk';
    repository: 'github://openponk/openponk/repository';
    load: 'complete'


The downloaded package contains with additional instructions, however on properly configured system launching (under Linux & Mac) or OpenPonk.exe (under Windows) should be sufficient.

Once launched, clicking on the desktop will show a menu containing entries for OpenPonk.


Windows and Mac should work out of the box.

Linux may require extra configuration as Pharo VM is still primarily 32bit. Please refer to Pharo's official guide.

Additionally you will require 32bit cairo2 library, usually available in distribution package managers as libcairo2:i386 (debian), libcairo2, etc.

The bundled launcher will check those requirements and will warn you and provide some tips if your system is not configured properly.
