Built by one developer.Not a corporation.
No recurring subscription, no tracking pixels, no venture capital. A native macOS app built to solve a problem I kept having myself.
Why I built it
I was tired of the state of macOS system monitors. Half of them were heavy Electron apps that drained the very battery they were meant to be watching. The other half gave me endless graphs and no context.
I kept finding myself staring at mds_stores or WindowServer in Activity Monitor, opening a browser, and searching "is it safe to force quit this process?"
I wanted a native, lightweight menu bar app that did not just hand me raw data. I wanted one that gave me an answer. So I built it. MacStats started as a personal project and grew into a full menu bar monitor built around clarity, privacy and understanding.
Native Swift
Built for macOS and tuned for Apple silicon. Roughly 1% CPU and 65 MB of memory while monitoring, so it does not cost you the battery it is watching.
Answers, not just data
A monitor should tell you what is happening, not only display it. The explainer says what a process is, why it is busy, and whether it is safe to touch.
Privacy by default
Your files, command-line arguments, documents, usernames and Bluetooth device names stay on your Mac. Only an explanation sends anything, and only the process name and coarse metrics.
Who is behind it
An independent software developer building native, high-performance tools for macOS, with more than ten years of engineering behind them.
Every copy of MacStats funds independent development and the next round of improvements. Thank you for that.
Why not the Mac App Store?
MacStats needs low-level system access for accurate CPU, memory and per-process data. The App Store sandbox blocks it, so MacStats is a direct download. That is also why the first launch shows a security warning, which the download page walks through.
