Show HN: Minimal container-like sandbox built from scratch in C
Sahil121 Sunday, December 07, 2025
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.
