Stats and Better Resource Monitor are both good menu bar monitors, but they suit different habits. Stats goes deeper into fans, thermals, and extra sensor detail. Better Resource Monitor keeps to the everyday numbers: CPU, memory, GPU, and network. If you want a Stats alternative that stays focused and does not add much overhead of its own, that narrower scope is the point.

What each app is optimized for
Stats covers more ground if you care about fan speeds, thermals, and deeper sensor data. Better Resource Monitor is narrower on purpose. It focuses on the four things most people actually check first when their Mac feels off: CPU, memory, GPU, and network usage.
Why Better Resource Monitor stays lighter
Better Resource Monitor sits under 0.1% CPU on Apple Silicon and uses about 15 MB of memory. Part of that comes from not chasing every possible sensor. If you mostly want quick visibility instead of a full hardware dashboard, the tradeoff makes the app easier to leave running all day.
Why it feels simpler to live with
The no-admin-password, no-root-helper approach is not the main reason to pick Better Resource Monitor, but it does say a lot about the app. It installs like a normal Mac app, is available on the Mac App Store with full features, and uses public APIs for GPU data. For most people, that means lower friction and fewer surprises. Stats is still a good pick if you want more sensors. If you mainly want to keep an eye on your Mac, notice unusual load sooner, and keep overhead low, Better Resource Monitor is on the Mac App Store and the source is on GitHub.
Comparison questions
What is Better Resource Monitor?
A free, open-source menu bar app that shows CPU, memory, GPU, and network usage on macOS. Written in Rust. Under 0.1% CPU and about 15 MB of RAM.
How much CPU and memory does it use?
Under 0.1% CPU and about 15 MB of RAM on an Apple M1. For comparison, Stats uses ~50 MB and iStat Menus uses 100+ MB. The app binary is under 7 MB.
How does GPU monitoring work?
On macOS, it reads device utilization from Apple Silicon GPUs through Apple's public IOAccelerator API. That keeps GPU monitoring available in both the App Store and GitHub versions without relying on private APIs or sudo.
Does it collect any data?
No. Zero network requests, no analytics, no telemetry. Everything stays on your machine. The source code is on GitHub if you want to verify that yourself.
Does it drain MacBook battery?
No. Monitors that poll fans and thermal sensors keep Apple Silicon from entering deep sleep. This app skips those readings entirely, which is why it sits under 0.1% CPU.
Is Better Resource Monitor a good Stats alternative?
Yes, if you want a Stats alternative focused on CPU, memory, GPU, and network. Stats is better if you need fan, thermal, and deeper sensor detail.
Why does Stats need more system access?
Stats goes deeper into fan and thermal readings, which can require a helper. Better Resource Monitor avoids that category of data and stays sandbox-friendly.
