Open-source software in Zorocut
Last updated: 2 November 2026
Zorocut's nesting engine runs on your computer, in the browser and in Zorocut Nest. Part of it is open-source research software, and we thank its authors. Zorocut itself is not open source. The notices below are reproduced as the licences ask.
