OpenToonz
Open-source full-featured 2D animation creation software
OpenToonz is a free, open‑source application for creating 2D animation, built on the legacy of the commercial Toonz system and adapted by Studio Ghibli for its own productions. It supports the entire pipeline from scanning hand‑drawn artwork with the GTS tool, through ink and paint, color design, and digital composition, to final footage export. The software includes an effects development kit that lets developers add custom image‑processing plug‑ins, and it offers a range of built‑in effects such as style changes, lighting adjustments, and wavy distortion.
The program is intended for professional studios, independent animators, educators, and hobbyists who need a complete animation suite without licensing fees. Its source code is released under the New BSD License, allowing unrestricted modification for both commercial and non‑commercial projects. By providing a research‑friendly platform, OpenToonz aims to bridge academic advances with practical production workflows.
