What Hacker News says?
sandbox-exec. It's not great, but it's usable. https://igorstechnoclub.com/sandbox-exec/ > It’s not any different It's very different. With docker on Mac you're running a VM which runs a wrapped up complete system that runs your app. With selinux/sandbox-exec you run just your app and can skip the extra packaging needed for docker and mounts. (And get the extra performance)

HN discussionthis approach is quite similar to what I use for rendering huge markdown files in https://mdview.io : 10MB files renders correctly and even Table of Content works. 15MB renders but scrolling is not as smooth as I wanted, will work on that.

HN discussionInteresting from a Docker perspective, but I’m more interested in it as a sandbox for AI agents and untrusted code execution. I wrote about that angle here: https://igorstechnoclub.com/sandbox-exec/ Feels like the spiritual successor to sandbox-exec, but with VM-level isolation.
