OpenToonz: sovereignty score and 8 European alternatives

OpenToonz is an open-source, full-featured 2D animation program. It is published by DWANGO, a company headquartered in Tokyo, and builds on the Toonz software originally developed by Digital Video in Italy and later customised by Studio Ghibli. The project's pages describe an installer for desktop use, so animation files are created and kept on the user's own computer rather than in a vendor-hosted service.

For a European organisation, the main points are source-code transparency and local deployment. The source code is published on GitHub under a Modified BSD licence, and some third-party components in the repository are subject to other terms. The company is based in Japan, outside the EU. Because the desktop application runs on the organisation's own systems, questions about data handling relate mainly to the local installation and to the licence terms of the components used, which should be reviewed before rollout.

Why digital sovereignty matters with OpenToonz

OpenToonz is headquartered in JP, outside the EU. Contracts and data therefore also fall under non-European law. The GDPR applies through contractual terms, but in a conflict with local legislation you have less certainty than with a European vendor.

OpenToonz hosts data outside the EU (OTHER). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

OpenToonz is open source. You can audit the source code, self-host the software and keep the encryption keys under your own control. Switching is easier because data and software are not tied to a single party.

What this means for your organisation depends on your whole stack and context. The free assessment weighs OpenToonz together with your other vendors and gives a total score, a heatmap and the main risk drivers.
