How Stats Compares With iStat Menus for macOS Menu Bar Monitoring

Updated

Stats is a free, open-source menu bar system monitor for macOS, and its own site positions it directly as "a free iStat Menus alternative." If your priority is broad at-a-glance monitoring at no cost, Stats covers the core categories well; if you need deeper per-feature polish or vendor support, iStat Menus remains the paid option to weigh against it. The comparison below uses the same dimensions for both, and notes where the available material only supports one side.

Feature coverage

Stats organizes monitoring into 9 modules and 13 menu bar widgets. The site lists these areas:

Area What Stats shows
CPU Real-time load, frequency, temperature, and a live list of the most demanding processes
GPU Utilization, memory, and temperature for Intel, AMD, and Apple Silicon graphics
RAM Memory pressure, used/free RAM, swap usage, top memory-consuming apps
Disk Free/used space, read/write activity, SMART health per drive
Sensors Temperature, voltage, power, and fan-speed sensors
Network Upload/download speeds, total data usage, local and public IP addresses
Battery Charge level, health, cycle count, time remaining, power source
Bluetooth Battery levels of connected keyboards, mice, headphones
Clock Customizable clock and calendar with multiple time zones

That is a complete set for everyday monitoring: it replaces opening Activity Monitor for CPU, memory, disk, and network checks. iStat Menus is widely known for covering similar categories, but the material here does not detail its feature list, so treat any claim of "Stats covers more" or "iStat covers more" as unverified until you check iStat's own documentation.

Customization

Stats lets every module appear as a chart, number, gauge, or dot, and you can combine, reorder, and color widgets. The listed widget styles are: mini, line chart, bar chart, pie chart, network chart, speed, label, tachometer, memory, battery, stack, dot, and text. This is a genuinely flexible menu bar — you can keep it minimal (a few dots) or dense (charts plus labels).

Whether this matches iStat Menus' customization depth is not established by the available material. If menu bar layout flexibility is your deciding factor, compare both apps' widget options side by side on your own machine.

Cost and licensing

Stats is described as completely free and open-source, with no ads, no tracking, and no subscriptions. It has 42.5k GitHub stars, 100M+ downloads, and 41 languages, suggesting a large, active user base.

iStat Menus is characterized here only as a "paid alternative." The specific price, license terms, and upgrade policy are not in the available material — check the vendor's site before budgeting. The practical trade-off: Stats costs nothing but relies on community development; a paid app typically funds dedicated support and faster feature response.

Compatibility and installation

Stats requires macOS 12 or later and runs natively on both Apple Silicon (M1, M2, M3 and later) and Intel Macs. The current download is v3.0.21. You can install it directly from the site or via Homebrew.

To install with Homebrew, run:

brew install --cask stats

Expected result: Stats appears in your Applications folder; launch it and its widgets appear in the menu bar. If the command fails, confirm Homebrew is installed and that your macOS version is 12 or newer. For direct download, use the link on mac-stats.com and drag the app to Applications.

iStat Menus' system requirements are not covered in the available material; verify them on its product page, especially if you run an older macOS version.

Support and project maturity

Stats cites 7 years of active development and an open-source codebase on GitHub, so issues and feature requests go through the community. That means no formal support contract, but transparency: you can inspect the code and track fixes. A paid product like iStat Menus typically offers vendor support, which matters if you manage Macs professionally and need a accountable channel.

How to choose

  • Choose Stats if you want comprehensive CPU/GPU/RAM/disk/network/sensor/battery monitoring at zero cost, prefer open-source software, and are comfortable with community-based support.
  • Consider iStat Menus if you need vendor-backed support, or after comparing its feature depth and price against Stats and finding it worth paying for.
  • Try both first if the decision hinges on menu bar aesthetics or a specific sensor reading — both can run on the same Mac, and you can judge widget flexibility directly.

One caveat for either app: menu bar monitors read system sensors and process data locally; confirm on each product's site how it handles any network-related features (such as public IP lookup) if privacy is a concern.
