These packages are used under their own licences — mostly MIT, BSD and Apache 2.0. Those licences require their copyright notices to be preserved, which is one of the reasons this page exists. The full licence text for each project is available from that project's own repository.
If you maintain one of these projects and would like your entry corrected, or removed, email us and we will act on it.
Ordis itself is proprietary software. Crediting the projects it is built on does not make Ordis open source.
