Some apps on your Mac keep going online, even when you would rather they stayed offline.
NetBlocker gives you a simple, quiet way to stop them.
Open NetBlocker and drag an app into the window. That's it. Its new network connections are blocked automatically.
NetBlocker also finds related helper apps, XPC services, and background processes, so a single app cannot hide behind several executables.
Everything stays grouped under one clear rule, with no connection prompts and no complicated lists to manage.
NetBlocker is a native Mac app for Apple silicon, signed and notarized by Apple.
