Show HN: Procinsh – A 3D Linux process inspector

I built procinsh, a 3D Linux process inspector inspired by Ghost in the Shell.

It visualizes running processes and their relationships in a 3D UI. Process activity, memory maps, file I/O, and socket communication are reflected in real time.

The backend is written in Rust and uses procfs, eBPF, ptrace, and process_vm_readv to collect information from the system.

this looks something pulled straight from a hacker tv show that I would have thought fake as hell

Over 20 years ago we had a doom in which your processes were represented by monsters and killing them sent the kill signal. :)

now I can finally live my dream of saying "it's a unix system I know this" in front of my family and non-technical friends while pulling this thing up and inspecting my bloated tmux processes running 20 claude code instances

Did a procfs scraper once, handling pids vanishing mid-read took me ages.

Obligatory reference to psDoom [1]. There’s something quite fun about killing the monster labeled “init” and poof! Your whole system is now dead.

Look at that FPS!! Now we need another inspector to monitor Procinsh.
