WhoIsCooking

Name: WhoIsCooking
Author: Andrew Wilson

WhoIsCooking is a $5 Mac menu-bar and notch app that shows which AI coding agent (Claude Code, Codex, Cursor and others) is heating your Mac and cools it by moving that work onto efficiency cores without stopping it.

Why it matters

For Mac users whose laptops run hot while coding agents start builds, tests and renders. It groups the dozens of processes an agent spawns into one row and lets you slow that agent down instead of killing it.

Highlights

Groups each agent session and everything it started (builds, tests, dev servers) into a single row.
Cool down moves heavy work to the efficiency cores; the maker reports a render dropping from 64°C to 50°C. Full speed restores it, and quitting the app always does.unverified
Nudges you when an agent burns CPU for five minutes straight or leaves dev servers running after its session ends.
Recognizes Claude Code, Codex CLI, Gemini CLI, Cursor, Aider, Copilot CLI, Ollama and LM Studio, plus Xcode, ffmpeg, Docker and browsers.
Signed and notarized by Apple; the maker says it idles at about 0% CPU and 14 MB of memory.

Taken from the project's own README, docs or launch page. Claims about speed or accuracy are the maker's unless stated otherwise.

Try it if: Your MacBook fans spin up every time Claude Code or Codex kicks off a build and you want to know which one is doing it.

Worth knowing: Cooling slows the agent's work while it's active.
