Hi Product Hunt 👋 I built NetBlocker because I wanted a very specific kind of Mac firewall: choose the apps that should stay offline, without approving every connection as it appears. The workflow is deliberately small: • drag an app into NetBlocker • related helpers and background processes are discovered and shown • new network connections from that app group are blocked • remove the app whenever you want to restore access This is not intended to replace Little Snitch’s network monitor or per-domain rules. It is for people who want a focused block list with a native Mac interface and no subscription. NetBlocker runs on Apple silicon Macs with macOS 13 or later. It is signed and notarized by Apple. There is a 7-day trial with no card, followed by a €4.99 lifetime license and a 30-day money-back guarantee. I would especially value feedback on the first-run setup and on apps that use unusual helper processes. I’m happy to answer any technical or product questions.
