ShizuWall — брандмауэр для Android без VPN

★ 2.1K

ShizuWall is a VPN-free Android firewall: it allows or blocks network access per app individually, without taking up the phone's VPN slot or routing traffic through itself. Reach for it when you want to stop specific apps from reaching the internet — for privacy, to cut background activity and trackers, or to save data — while keeping your regular VPN free to use. It runs locally and privately with no cloud; access control goes through Android's Chain 3 mechanism (`cmd connectivity set-package-networking-enabled`), which requires Shizuku, a local ADB daemon, or root, and Android 11 or newer. Its focus is firewalling apps' outbound access using the OS's own controls, not building a VPN tunnel or filtering content inside traffic: it is a privacy utility for a personal device that needs elevated access via Shizuku, ADB, or root.
