What native runtime is Open Container Initiative (OCI) compliant?

runC is a lightweight, portable container runtime that serves as the reference implementation for the Open Container Initiative (OCI) Runtime Specification. It is directly used by higher-level container runtimes like containerd and CRI-O to manage the lifecycle of individual containers, ensuring OCI compliance.

runV is a container runtime for virtual machines, offering a different isolation model than runC.

Kata Containers is an open-source project that provides lightweight VMs that feel and perform like containers, but they integrate with OCI runtimes rather than being the native OCI runtime itself.

gVisor is an application kernel that provides an isolation boundary between the running application and the host operating system, offering a different security model.
