Competitors mentioned: Uptime Kuma, native rust libs, System Informer, btop
Concerns raised: Parsing ss output is fragile when output format changes, High memory usage for GTK4 application (130+ MB per instance), Slow startup time, Only shows /proc fs contents, not real-time connection details, AI slop in presentation
Feature requests: Use jc program for JSON parsing instead of regex, Use eBPF/XDP for real-time network protocol insights, Larger main screenshot showing actual application data view, Light/dark mode toggle, Windows-style power-user process explorer features
