Show HN: Minimal container-like sandbox built from scratch in C
Runbox recreates core container features without relying on existing runtimes or external libraries. It uses namespaces, cgroups v2, and seccomp to create an isolated process environment, with a simple shell for interaction.
For future gonna work on adding an interface so external applications can be executed inside Runbox, similar to containers.
