ChibiPaint 0.7.11.2 for Mac was available to download from the developer's website when we last checked. We cannot confirm if there is a free download of this app available. This free Mac app was originally developed by Marc Schefer. The software relates to Design & Photo Tools. We recommend checking the downloaded files with any free antivirus.
From the developer:
ChibiPaint is an open source Oekaki applet, a software that allows people to draw and paint online and share the result with other art enthusiasts. You can start using it right now on this website in the Oekaki Board section or download it and integrate it into your own website.
You may want to check out more software for Mac, such as Cuadro or Resize Now, which might be similar to ChibiPaint.
