Show HN: Nucleus – A security-hardened, Nix-native container runtime
Nucleus is a lightweight, security-hardened container runtime designed for Nix-based environments that prioritizes declarative configuration over traditional image-based workflows. By leveraging Linux kernel primitives like Landlock and seccomp, it provides high-performance, isolated execution for ephemeral or untrusted workloads without the overhead of standard container engines.
Why it matters
It offers a specialized alternative for infrastructure engineers who require stronger security guarantees and reproducible, audit-ready deployments that standard Docker-based workflows cannot easily provide.
