CoreOS is a mid-sized software development company based in San Francisco, California, and is part of the Red Hat family. It contributes to the open-source ecosystem by building components for containerized applications that support secure, scalable, and resilient infrastructure. The organization maintains open-source projects such as Container Linux, a securely updating operating system, and etcd, a distributed data store used with Kubernetes. Its offerings target developers and operators who run cloud-native workloads and seek reliable container runtimes and orchestration capabilities.

In the broader container infrastructure space, CoreOS aligns with Red Hat to integrate and advance open-source tools for enterprise use. A notable recent development is the January 2023 introduction of Rocket, a portable container format intended as an alternative to the Docker runtime.
