Stat Space vs iStat Menus
An iStat Menus alternative for developers
iStat Menus is the long-standing, polished way to put system stats in your menu bar. Stat Space covers the same basics for free and spends its effort on the developer side: ports, agents, orphaned processes and keep-awake.

Where iStat Menus shines
- Deep, polished system detail with long-range history graphs.
- Weather, calendar and time zones in the menu bar.
- Years of refinement, and it supports Intel Macs too.
What Stat Space adds
- The system basics are free, with no trial.
- Ports traced to their project and launcher; stop, open or share one in a click.
- AI agent sessions and the servers they leave running.
- A CLI and MCP server so agents can query and clean up your Mac.
- Keep-awake built in, with the reason it’s on.
Use both?
If you rely on iStat Menus’ history graphs or weather, keep it and add Stat Space for the developer tabs. Turn off Stat Space’s menu bar modules you don’t need; samplers only run for what’s visible.
