SystemWoe vs ProcessSpy
ProcessSpy is a strong Mac Process Explorer analogue — identity, trees, cmdline. SystemWoe takes a different path: I/O leaderboards, a curated process encyclopedia, and safe ways to free capacity.
Verdict
Use ProcessSpy when you need deep process identity and explorer workflows. Use SystemWoe when the question is “what is eating disk/net — what is it — and how do I free capacity safely?”

Pick ProcessSpy when
- You live in process trees, argv, env, and signature detail
- You want a Process Explorer mental model on macOS
- Setapp already covers your toolkit
Pick SystemWoe when
- Disk or network pressure is the pain, not identity alone
- You want plain-English explanations that improve over time
- You need Docker-aware keep-guards and Free Resources recipes
ProcXray sits in a similar “inspect depth” lane — still without a curated process encyclopedia. Pricing notes are approximate (2025–2026).
