+## [rk8s](https://github.com/rk8s-dev/rk8s)
+
+A lightweight Kubernetes-compatible container orchestration system written in Rust, implementing the Container Runtime Interface (CRI) with support for single containers, Kubernetes-style pods, and Docker Compose-style multi-container applications.
+
+Uses: `libcontainer`, `libcgroups`
+
+## [runwasi](https://github.com/containerd/runwasi)
+
+A containerd shim that runs WebAssembly workloads in Docker and Kubernetes while using an OCI-compatible sandbox.
+
+Uses: `libcontainer`
+
+## [SpinKube](https://www.spinkube.dev/)
+
+A platform for running Spin applications on Kubernetes. SpinKube uses `runwasi`, which in turn uses `libcontainer` to provide an OCI-compatible sandbox for workloads.
