Kiri - Open-source Rust container runtime with 18 ms Docker runs

Show HN: Kiri – an open-source container runtime in Rust, Docker run in 18 ms

Kiri is an open-source container runtime written in Rust that dramatically speeds up container startup, running a Docker container in just 18 milliseconds. Built for developers who are tired of waiting on slow, heavyweight runtimes, it delivers a lean, fast alternative that fits into existing workflows without friction. Whether you're spinning up containers for local development, CI pipelines, or latency-sensitive workloads, Kiri shows how Rust's performance and safety can reshape the container landscape. The project is fully open source, so you can explore the code, try it out, and contribute to its growth.

Hi HN. I built Kiri because container startup shouldn't be something you wait on — Docker run in 18 ms changes how you think about containers.
