CPU, RAM, network & temperature in your macOS menu bar

A native macOS menu bar monitor written in pure Swift — no Xcode project, no third-party dependencies, minimal CPU and memory footprint. Three columns at a glance: network up/download speeds, CPU load and RAM usage, and average CPU temperature. Colors shift from green to red as load climbs. Open the menu to see which apps are eating the most CPU and memory — helper processes roll up into their parent app, and system daemons are filtered out. Apple Silicon + Intel, macOS 11+.

Hey Product Hunt 👋
MacStats is a native macOS menu bar monitor written in pure Swift.
Three columns, always visible:
• Network — live upload/download speeds, units auto-scale (B/K/M/G)
• CPU & memory — live load % and RAM usage, color-coded green to yellow to red
• Temperature — average CPU temp, °C or °F
Open the menu and it ranks the apps currently eating the most CPU and memory. Helper processes (all those browser renderers) roll up into their parent app, and background system daemons are filtered out, so you only see the apps you actually recognize.
Some of the technical choices:
• No Xcode project — a plain build script invokes swiftc directly and assembles the .app bundle
• No third-party dependencies
• Runs as a background accessory (LSUIElement), so no Dock icon and no Cmd-Tab clutter
• Polls Mach and BSD APIs directly, with no allocations in the network hot loop
• SMC temperature sensors are discovered dynamically at startup, so it works on both Apple Silicon and Intel
Install and uninstall are each a single command, both in the README — and uninstalling cleans up login items and preferences rather than just deleting the app.

Happy to answer any questions!
The rolling helper processes up into their parent app while filtering out system daemons is a really thoughtful touch. That kind of detail usually requires someone to actually live with their own tool for a while.
Love how lightweight this is, finally a menu bar monitor that doesn't hog resources itself. One thing I'd love to see is a quick toggle to disable the temperature column on Apple Silicon, since not everyone needs it and it could shave off a bit more overhead for people running it on older machines.
finally a menu bar monitor that doesn't feel like it was designed in 2005, the three-column layout in the icon is genuinely useful and the helper process rollup actually makes the menu readable. solid little app
the parent app rollup for helper processes is a really thoughtful touch, makes the dropdown way less noisy than activity monitor. nice work keeping it dependency-free
the helper-process rollup into parent apps is a really thoughtful detail, makes the breakdown actually readable instead of a wall of system noise. love that it's pure swift with no dependencies too.
