PortGlance
Localhost and system monitor
Only for Mac
Free
Mac
PortGlance is a lightweight menu bar monitor for developers and Mac users who want a quick read on local system activity.
See localhost availability, network speed, CPU, memory, thermal load, and top resource apps in one clean panel. PortGlance helps you notice when a local preview server is still reachable, when network traffic is active, or when an app is likely contributing to heat.
Highlights:
• Menu bar status panel for CPU, memory, network, and thermal load
• Localhost checks for common development ports
• Resource ranking for visible apps, grouped by CPU, memory, and estimated heat contribution
• Optional Safari and Chrome tab linking with macOS permission
• On-device settings, language options, and privacy notes
PortGlance is designed to be read-only. It does not require an account, does not include ads, and does not upload your system status or browser tab information to a developer server.
