Open source & attributions
Atelier is proprietary software, but it is built on the shoulders of open source. This page sets out what it is built from and where to find the full attributions.
What Atelier is built from
Atelier’s own binaries and web UI link in a few hundred open-source components:
- around 330 Rust crates compiled into the binaries (
atelier-core, the installer, and supporting tools), and - around 115 npm packages bundled into the web UI.
Every one of these is under a permissive license (MIT, Apache-2.0, BSD, ISC, Zlib, Unicode, and similar). There is no copyleft (no GPL, LGPL, AGPL, or MPL) compiled into Atelier, by design.
Full attribution notices
The complete list of components, with the full text of every license, is in
a generated THIRD-PARTY-NOTICES.md file. It is published with every
release (as a release asset and at the canonical download path), and a current
copy is served here:
It is generated directly from the dependency tree, so it stays accurate as dependencies change.
Components Atelier runs alongside
Separately from what is compiled in, Atelier deploys or interoperates with larger open-source systems that ship as their own projects, including k3s, Gitea, Traefik, BuildKit, Trivy, and Longhorn. These are not bundled into Atelier; they are pulled as their own upstream images and run in your cluster, and they carry their own licenses and notices. The same applies to external services Atelier can connect to. Their trademarks and the non-endorsement position are covered on the Disclaimer & risks page.
