Description
NetBlocker is a deliberately simple outbound firewall for Apple silicon Macs. Drag an app into the list to block its new network connections. NetBlocker also discovers and displays related helpers, XPC services and background processes, so one rule covers more than the visible app. There are no connection-by-connection popups, accounts or subscriptions. It includes a 7-day free trial, costs €4.99 once and comes with a 30-day money-back guarantee.

Could you build this?
No Implementing a system-level outbound application firewall on macOS requires writing and notarizing a Network Extension (NEFilterDataProvider) in Swift/C with low-level OS entitlement handling.
What it would actually take: A real app requires an Apple System Extension utilizing the NetworkExtension framework, specifically `NEFilterDataProvider` or `NEFilterPacketProvider`. The core challenge is low-level packet inspection, process tree attribution (tracing XPC helpers and daemons back to parent app bundles), and securing specialized Network Extension entitlements directly from Apple, which cannot be vibe-coded.
