Zen

Free open-source desktop app blocking ads and trackers system-wide across all apps.

Desktopfree

A free, open-source desktop app that blocks ads and trackers at the network level across the system, covering all browsers and most desktop applications. It reduces the need for multiple extensions, hosts-file edits, or manual configurations by providing one install that enforces system-wide ad and tracker blocking, aimed at privacy-conscious users who need protection beyond browser tabs.
