Open source notices

Last updated 29 September 2026

3D Thing is built on open source software. We are grateful to the people who make it. Their licences ask us to keep their copyright notices with the software, and this page and the full notices file do that.

Full third-party notices (text file) with every package, its version, licence and copyright notice.

None of them is under a licence that would require us to publish our own source code. Our servers also run open source Python packages; that software is not distributed to you, and none of it requires us to publish our code either.
