Nuke is a node-based compositing application for visual effects. The developer describes it as a compositing toolkit with more than 200 nodes and as an industry-standard tool for compositing. It is sold as part of the Nuke family of products, and the product page does not describe a hosted service.
The Foundry Visionmongers Ltd is registered in England and Wales and based in London, so it is a UK company outside the EU. Roper Technologies, a US diversified technology group, assumed ownership of The Foundry from the private equity firm Hg in 2019, and the company says the arrangement lets it remain independent. The privacy notice says personal data may be stored outside the UK and EEA, including with Roper Group affiliates in the United States, and it refers to both the UK and EU GDPR. A European organisation should therefore weigh the US parent and transfers to the United States.
