Online Judge Engine Powered by runC, gVisor and other execution runtime.
The only prerequisite is downloading and run containerd, which works on distribution of any Linux or WSL.

}The Judge Service is defined in GRPC Service, hence both embedded service and remote service are supported. And, the OCI Standard has been implemented as a tarus judge service (runtime), so most oci-runtime are soon available in this framework, including runC, gVisor and Kata Containers.
Also, the judge proxy service such as Kafka Gateway is on the way, which can connect multiple judge runtime services and provides more functionality for users.
