Third-Party Notices

Effective September 21, 2026

This page lists the third-party software included in the Solidly application for macOS, and carries the notices those licenses require. The Acknowledgements document inside the application bundle, which you can open from About Solidly, carries the same notices for the application.

This page also credits the 3D models shown in the videos on this website and in the App Store preview video, which are not part of the application and so are not in the bundled document. Credits for the website itself, including its typography and the software it is built with, are on the Attribution page.
