Updated Nov 10, 2026, from what MacPip lists today.
Short answer
MacPip lists 5 system monitoring apps for Mac, and a person has checked none of them yet.1 of them has a free version.4 of them sell a one-time license.There is no single best system monitor for everyone, so MacPip does not rank them.If you want it free, start with Netfox.
Apps a person checked come first, newest check first. Never ordered by payment.
What these 5 apps offer, by their listings. An app can offer several, so the bars do not add up to 5.

One-time price in US dollars, as each listing states it, lowest first. 2 apps have no plain dollar one-time price and are left out. Launch prices count where the listing says so.
From its maker: Mole helps you review leftovers after uninstalls, clear caches, and see what's using disk space before anything is deleted. The command-line tool is free and open source.
From its maker: WiAware lives in your Mac’s menu bar and tells you, in plain words, whether your connection is good enough for a call. The icon is the answer: a full wave means calls are fine, a broken wave means they may stutter, and a dot means they won’t work.
From its maker: An Activity Monitor alternative for Mac: every process grouped under its app, with live charts, 30 days of history, alerts and a menu bar monitor. $5 at launch.
From its maker: Netfox turns raw network data into plain English on your Mac: decode every device, see what it exposes, and catch services left open. No cloud, no account.
Look for low overhead of its own, which sensors it reads on Apple silicon, and whether it can live in the menu bar.
