CoreOS was acquired by Red Hat, and now "Fedora CoreOS".offers similar concepts.

Conveniently, RH also invented both Podman and systemd.

Note: similar, but definitely not the same. The real continuation of CoreOS was Flatcar Linux (https://www.flatcar.org/), but then the company behind that was bought by Microsoft (https://kinvolk.io/blog/2021/04/microsoft-acquires-kinvolk/) and I really don't expect much of them anymore...
