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 on your Mac. It also answers developer questions: which process is listening on a given port and which terminal, editor or AI agent started it, what Claude Code, Codex or Cursor left running after a session, and what is keeping your Mac awake. Extras include per-app volume sliders, keep-awake timers, a statspace CLI with an MCP server, and twelve menu bar looks. Free to use with no account; Pro is a one-time purchase with no subscription.
