Kiri – The Modern Container Runtime

Kiri is a modern container runtime that simplifies running Docker containers with a single daemon. It maintains compatibility with existing Docker tools like the docker CLI, Compose, and the Docker API. Benchmarks show Kiri's efficiency compared to Docker Desktop, Colima, and OrbStack, with 8× faster container start times on Apple Silicon Macs.

A free, beta version is available on macOS, Windows, and Linux. Users can provide feedback through the Kiri window for bug reports and improvements. Kiri supports up to ten containers on a single runtime, with each container using minimal CPU and memory resources. It provides a name for every container, integrates with Kubernetes, and generates public links for sharing containers.

Kiri also offers an intuitive user interface with container management features, live stats, logs, a terminal, and file access. The runtime is built on a single daemon that manages namespaces, cgroups, and mounts for each container, reducing overhead compared to running a shim per container. Kiri's benchmark results demonstrate its speed and resource efficiency, making it a promising alternative to traditional container runtimes.
