Vitals

Activity Monitor lists processes, about a thousand on a working Mac, and leaves the adding up to you. Vitals lists apps, with every helper added to the app that launched it, and lets you click any process to see who signed it, what started it and what it has used. It adds up to a year of history, notifications, your coding agents and AI plans, and a menu bar you arrange.

Yes. The CPU, memory, energy, disk and network tabs each put the busiest app at the top, and Vitals points out an app that keeps the CPU busy, keeps growing in memory, or hammers the disk. Click the app and everything about it is in one place.

Click any process in Vitals and its drawer shows the rest: the app it belongs to, its code signature and Team ID, entitlements, parent process and launch agent, full command line, open files, ports and child processes, and the CPU and memory it has used since it started. You can copy it or save it as CSV, and the same details come from vitals process in Terminal.

Yes. Turn on Let AI Assistants Ask Vitals in Settings, then add Claude, Claude Code, Codex, Cursor or any assistant that speaks MCP in one click. An assistant can ask what is running, what is on a port and what the last days looked like, but it cannot quit anything on its own: Vitals asks you first in its own window.

Yes. The vitals command shows the whole Mac, the busiest apps, ports, projects, containers, coding agents, AI plan limits, history and any single process, as a table or as JSON. Vitals puts it on your PATH when you turn it on, or install the app and the command together with Homebrew.

Yes. You pay once and every update is included, with no paid upgrades and no renewal. The Process Inspector, the Agents tab, the CLI and the MCP server all arrived as free updates.
