What is stats?
Stats is a free, open-source system monitor for macOS that puts CPU, GPU, memory, disk, network, sensors, battery and Bluetooth readings in the menu bar. It is MIT-licensed and published on GitHub by a single maintainer, Serhiy Mytrovtsi, and the README states it requires macOS 12 Monterey or later, with beta versions of macOS unsupported. Each of its nine modules can be shown as a chart, a number, a gauge or a dot, and modules can be combined and reordered. It runs on both Apple Silicon and Intel Macs. The project is open source but not open-contribution: the README states that unsolicited pull requests are generally not accepted. Optional remote monitoring is handled by a separate service, System Stats, which is not the free app.

Key features
What stats does at a glance.
CPU, GPU, memory, disk and network monitoring
In the menu bar
Hardware sensors
Temperature, voltage, power and fan speed
Battery level, health, cycle count and power source
Battery levels of connected Bluetooth devices
Multi-time-zone clock and calendar
Thirteen widget styles
Including charts, gauges, dots and text
What you can use stats for
- Checking CPU and memory load while a build or render is running
- Watching network throughput and disk activity from the menu bar
- Monitoring battery health and cycle count on a MacBook
- Reading temperatures, voltage and fan speed from the hardware sensors
- Keeping an eye on the battery levels of connected Bluetooth devices
Who is stats for?
- Mac users who want system readings visible at all times in the menu bar
- People monitoring a headless Mac through the developer's SSH install script
- Users who prefer a free, MIT-licensed tool over a paid menu bar monitor
Who is stats not for?
- Windows or Linux users — Stats is a macOS menu bar app
- Anyone who needs working fan control — the README lists the fan-control module as no longer maintained
- People who want to contribute code — the README states unsolicited pull requests are generally not accepted
Limitations
- macOS 12 Monterey or later is required, and beta versions of macOS are not supported
- The fan-control module is listed as no longer maintained
- Remote monitoring is handled by the separate System Stats service, which is not the free app
Strengths and trade-offs
What stats does well, and what to weigh before choosing it. Points marked developer-stated come from the developer’s own material and have not been independently confirmed.
Strengths
- Open source under the MIT licence, with the full source published on GitHub.
- Free to download and use, with no ads, tracking or subscriptions.
- Installs directly as a .dmg, via Homebrew, or through an SSH script for headless remote monitoring.
Trade-offs
- Developed and maintained by a single person; the README states unsolicited pull requests are generally not accepted, so outside contributions are limited.
- The README lists the fan-control module as no longer maintained.
First-use experience
What the app asks of you when you set it up. Only established facts appear here; anything we could not confirm is left out rather than guessed at.
- Installation
- Download Stats.dmg from GitHub Releases and move it to Applications, run 'brew install stats', or use the developer's SSH install script for a headless setup.
- First launch
- Launches as a menu bar app with modules that can be enabled and arranged; some readings, such as Wi-Fi names, require Location permission.
- System integration
- Lives in the menu bar and reads hardware through a privileged SMC helper installed with the app; removing it requires the bundled uninstall script.
- Apple Silicon
- Supported
What it does
Stats is a system monitor that lives in the macOS menu bar. It reads CPU and GPU utilisation, memory pressure, disk space and activity, network throughput, hardware sensors (temperature, voltage, power and fan speed), battery health and Bluetooth device battery levels, plus a multi-time-zone clock. It is free and open source under the MIT licence.
Modules and widgets
Nine modules — CPU, GPU, RAM, Disk, Sensors, Network, Battery, Bluetooth and Clock — can each be shown as one of thirteen widget styles, including a mini readout, line and bar charts, a pie chart, a speed gauge, a tachometer and plain text. Modules can be combined into a single popup and reordered.
One caveat from the README: the fan-control module is listed as no longer maintained.
Open source, not open contribution
The full source is published on GitHub under the MIT licence. The README is explicit that this is not an open-contribution project: Stats is developed and maintained by a single person, and unsolicited pull requests are generally not accepted. The stated ways to help are bug reports, translation improvements and ideas raised through issues.
Installation and remote monitoring
Stats can be installed from the Stats.dmg in GitHub Releases, with Homebrew
(brew install stats), or through the developer’s SSH install script, which
sets the machine up as a remote monitoring agent. The app itself is free; the
remote dashboard it can report to, System Stats, is a separate service.
Requirements and privacy
The README states Stats supports macOS 12 Monterey and newer, and that beta versions of macOS are not supported — only stable releases. It does not collect telemetry or analytics; the README lists the two endpoints the app contacts for update checks and the public IP lookup.
Apple Silicon
The developer’s site states Stats is built for both Apple Silicon (M1, M2, M3 and later) and Intel Macs. That is the only architecture statement Nuanyue found in a first-party source, so it is recorded as supported.
Release history
Dated releases recorded for stats, newest first, each with the source it was read from.
3.0.20
Fixes Sensors alignment in combined modules and stops querying Wi-Fi SSID/BSSID without Location permission; adds new sensor mappings and SMC caching improvements.
Source: Source repository
3.0.19
Hot fix that removed the Network system_profiler Wi-Fi fallback to prevent latency spikes and made Location permission requests explicit.

Questions about stats
Is Stats free?
Yes. It is free and open source under the MIT licence, and the developer states there are no ads, tracking or subscriptions. The separate System Stats remote dashboard is a different service.
Which macOS versions does Stats support?
macOS 12 Monterey or newer. The README states that beta versions of macOS are not supported — only stable releases.
Does Stats run on Apple Silicon?
Yes. The developer's site states it is built for both Apple Silicon (M1, M2, M3 and later) and Intel Macs.
How do I install Stats?
Download Stats.dmg from GitHub Releases and move it to Applications, install with 'brew install stats', or run the developer's SSH script to set a machine up as a remote monitoring agent.
Can I contribute to Stats?
The project is open source but not open-contribution. The README states it is developed and maintained by a single person and that unsolicited pull requests are generally not accepted; bug reports, translation improvements and ideas raised through issues are the stated ways to help.
Alternatives to stats
Apps that could replace this one — the same job, a different trade-off.
iStats
Command-line system information tool.
Both report Mac system information, but iStats is a command-line tool while Stats lives in the menu bar.
Competitors
Direct competitors: overlapping features aimed at the same users.
iStat Menus
Menu bar system monitor with sensors, notifications and fan control.
Both are comprehensive menu bar system monitors covering CPU, GPU, memory, disk, network, sensors and battery; iStat Menus is a paid, closed-source app while Stats is free and MIT-licensed.
Compared with
Head-to-head comparisons Nuanyue has published.
gfxCardStatus
Monitor graphics card usage and battery impact.
Both report GPU usage and battery impact in the menu bar, but gfxCardStatus focuses on graphics switching while Stats covers the whole system.
Works well with
Not a replacement — apps commonly used alongside this one.
Bartender
Menu bar manager with hiding, triggers and a second bar.
Stats supplies the menu bar readings and Bartender manages the menu bar itself, so the two occupy different roles.
