Stat Space

Stat Space is a native menu bar system monitor for Apple Silicon Macs running 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 back to its project folder and the terminal, editor, AI agent or Docker container that started it, and cleans up servers and orphaned processes left behind by Claude Code, Codex and Cursor sessions. It also offers per-app volume sliders, keep-awake timers, a statspace CLI with an MCP server, and twelve customisable menu bar looks. It idles under 0.3% CPU. The free version needs no account and has no trial; Pro is a one-time purchase with no subscription.
