New WhoIsCooking

WhoIsCooking is a $5 Mac utility that solves a very specific problem: when coding agents like Claude Code, Codex, and Cursor run builds, tests, or renders, your MacBook gets as hot as a stovetop—but you have no idea who's causing the heat.

It lives in the screen notch, shows the chip temperature, and consolidates each agent session and all the subprocesses it spawns (builds, tests, dev servers) into a single row—no more dozens of cryptic process names in Activity Monitor. When you click “Cool Down,” it moves heavy work to the Mac’s efficiency cores; tasks keep running, just a little slower. The official site’s tests show the same rendering task dropping from 64°C to 50°C. Click it again when you want full speed. It won’t freeze or kill any processes unless you explicitly ask it to.

One-time purchase, no subscription. Apple Silicon only, macOS 14 or later. A small, specialized tool that’s useful for people running local agents on their laptops.
