macOS system dashboard for your terminal. No sudo, no mouse.
Why
We spent years in fancy web UIs. Now we are back in the terminal, hours a day.
So I wanted this in the same window. Not another app to alt-tab to.
Then I added what I keep losing track of. Localhost servers, because I run a few projects at once and always forget one. Claude sessions, because I run several agents in parallel and I want to know which one is cooking the machine. My opinion on Claude Code is well known.
Install
No Homebrew, or Homebrew is shouting at you about Xcode:

Rust toolchain:
Then run whirr.
Apple Silicon only. Intel Macs don't expose the power channels this reads, so there would be nothing to show.

Performance
Under 0.5% CPU, under 25 MB, left running all day.
The process table is read with raw libproc calls, about 1 ms a pass instead
of the 35 ms a full sysinfo refresh costs. Three sampler threads at 2, 5 and
10 seconds. The screen redraws only when something changed.
One network request
Once a day whirr asks crates.io if there is a newer version, and says so in the
footer if there is. Nothing else leaves your machine. --no-update-check and
there are no requests at all.
