Free firewall vs. privacy intelligence
A simple allow/block firewall covers the basics. NetMute is built for privacy intelligence: a per-app firewall plus tracker detection, a privacy score per app, traffic monitoring, network profiles and reports — so you understand what your Mac is doing, not just gate it.
What LuLu can and cannot do
NetMute identifies 1100+ known trackers automatically, scores each app on what it contacts, monitors traffic in real time, and lets you set different rules per network. Instead of deciding every connection by hand, you get a clear privacy picture and smart presets.
Free vs. freemium
NetMute is free to download from the Mac App Store. Premium features (Privacy Dashboard, App X-Ray, full tracker database) unlock via a one-time in-app purchase — no subscription. The value question is what privacy intelligence is worth to you: NetMute automates the tracker research you would otherwise do by hand.
