Stat Space

Stat Space is a native menu bar system monitor for Apple Silicon Macs (macOS 14 Sonoma or later). It tracks CPU, GPU, memory, network, disk, battery, temperatures, fans and power, with 30 days of history stored locally. Built for developers, it traces every listening port to the project and the terminal, editor, AI agent or Docker container that started it, cleans up servers and orphaned processes left behind by Claude Code, Codex and Cursor sessions, and shows what is keeping your Mac awake. It also offers per-app volume sliders, keep-awake timers, a statspace CLI with an MCP server, and twelve customisable menu bar looks. It aims to stay under 0.3% CPU at idle. Free to use with no account and no trial; Pro is a one-time purchase with no subscription.
