The tools that build and test every distro are public, and so is every distro in the Library. Read them, copy them, or send a change.

The pipeline: turns a spec into an ISO, boots it five ways in QEMU, installs it to a disk and checks the result. Also the installer, the boot checks and the reusable GitHub Actions workflow every build runs.
github.com/Eric-Ness/linuxlive-distro · MIT-0
The template behind "Build it in my GitHub": one spec, its art and a workflow. Make your own copy and GitHub builds and boot-tests your distro for free.
github.com/Eric-Ness/linuxlive-library · MIT-0 (each distro under its own licence)
The Library: every distro on linuxlive.com/library is a folder here, added by pull request, reviewed, then built, boot-tested and published by its workflows.
The website itself (linuxlive.com and its sign-in service) is not public yet.
Every ISO is made from these projects, and many more inside Ubuntu and Fedora. linuxlive is not made or endorsed by any of them. For the source of what is inside an ISO, see Getting the source code.
