NetMute

Apps track you. NetMute hangs up.

NetMute is a per-app firewall for macOS that sits in your menu bar and shows which app is contacting which domain right now. One click takes any app offline. App X-Ray lists every connection per app and grades each app from A to F. Tracker Shield blocks known tracker and ad domains system-wide. Per-app data limits protect you on hotspot and tethering, profiles switch automatically per Wi-Fi, and the weekly report shows who is listening the most. Built on Apple's Network Extension: local-first, no account, no subscription — all network analysis runs entirely on your Mac.
