OpenToonz

OpenToonz is an open-source 2D animation program originally from Studio Ghibli’s Toonz software, available for macOS. It supports frame-by-frame animation, scanning paper drawings, and adding effects via a node-based compositor. Artists can manage multiple layers, apply color in a separate paint phase, and utilize plug-ins for scanning line art. OpenToonz’s advanced features (like Ghibli’s wavy distortion effect) suit both amateurs and professionals who want a powerful, no-cost tool. With a steep learning curve, it’s ideal for serious animators seeking robust features on Mac.
