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. It also answers developer questions: what is listening on a given port and which terminal, editor or AI agent started it, what Claude Code, Codex or Cursor left running, and what is keeping the Mac awake. Extras include per-app volume sliders, a CLI with an MCP server, and twelve menu bar looks. The free version needs no account; Pro is a one-time purchase.
