Accurate descriptions, without the marketing fog.
These passages may be quoted or adapted for editorial coverage.
NetBlocker gives Mac users a quiet way to keep selected applications offline. Drag an app into its window and NetBlocker blocks new outbound connections from that app while showing confidently associated helpers, XPC services, and background processes in context. It does not inspect traffic contents or ask the user to approve every connection.
NetBlocker is organised around the apps a user deliberately chooses to keep offline. Its focused interface avoids a system-wide connection feed and keeps related components with the parent app the user recognises.
Blocking decisions are made locally using Apple's Network Extension framework. NetBlocker does not read web pages, passwords, messages, or the contents of network traffic. Trial rules remain on the Mac.
