It's lightweight, fully native, and built for both Apple Silicon (M1, M2, M3 and later) and Intel Macs.

Best of all, Stats is completely free and open-source. There are no ads, no tracking and no subscriptions - just a fast, customizable menu bar monitor trusted by millions of Mac users and translated into 41 languages. Download it directly or install it with Homebrew, then tailor every widget to the way you work.
