Why I built it

I kept disabling my own blockers on impulse. So I built one that fights back — a root-level daemon, anti-tamper locks, and extensions for every browser that matters.

What it does

• 01System-level DNS blocking via /etc/hosts — works across every browser on the machine
• 02Background daemon running as root — survives restarts, resists force-quit
• 03Process monitor that terminates blocked apps within seconds of launch
• 04Browser extensions for Chrome, Firefox, Safari, Edge, Brave, Opera, Vivaldi
• 05Lock modes: timer, random-text challenge, schedule-based
• 06Anti-tamper blocks uninstall and System Settings while a lock is active

What I learned

My first full native macOS app — Swift, SwiftUI, a LaunchDaemon, XPC IPC, and six browser extensions shipped in parallel. Privilege escalation, notarisation, cross-browser packaging — the full surface area of shipping real software.
