Score: 7.3/10 (Innovation: 7, Technical: 8, Documentation: 7, Utility: 7)

Kiri is a lightweight container runtime for macOS, Windows, and Linux written in Rust that replaces Docker Desktop and OrbStack by running containers in a small Linux VM (or directly on the kernel for Linux) and exposing the Docker Engine API. It claims dramatically faster container startup (~2.5 ms), low memory footprint (~15 MB daemon), and compatibility with Docker CLI, Compose, and buildx, plus extras like local domains and a one-command Kubernetes cluster.

Target audience: developers, devops engineers, backend developers
