Your Mac’s Pulse, Delivered to iMessage & WhatsApp

Walk away from your desk while Claude Code runs, Xcode compiles, or Blender renders. MacMetrics sends a crisp 4-line telemetry brief straight to your iPhone, Apple Watch, or WhatsApp — on a schedule or the instant your Mac hits thermal or memory strain.

Watch MacMetrics in Action

See how MacMetrics tracks live Apple Silicon telemetry, groups helper processes, reclaims RAM from forgotten dev servers, and unlocks with a single $10.99 license key.

Everything your Mac is doing, explained in plain English.

Built natively in Swift & SwiftUI with direct IOKit, Mach kernel, and CoreAudio telemetry.

App-Centric Process Grouping

Instead of 45 confusing Google Chrome Helper (Renderer) rows, MacMetrics rolls every child helper into one clean application card with sub-role breakdowns.

Google Chrome (24 helpers) — 3.42 GB RAM · 14.2% CPU [Safe to Quit]

Forgotten Dev Server & Port Cleaner

Automatically detects idle Node, Vite, Next.js, Python, and Docker listeners holding RAM on ports like :3000, :5173, and :8080 so you can free gigabytes in one click.

localhost:3000 (node · next-server) — Idle 4h 12m — 612 MB [Stop Idle]

Native CLI (macmetrics) & MCP Server with 3-Tier Quit Safety

Query live system telemetry from your terminal or connect AI agents via Model Context Protocol. Built-in QuitCheck guardrails (do_not, ask_first, safe) prevent agents from ever killing system daemons or their own parent terminal.
