Pi-hole
Pi-hole blocks Internet advertisements by acting as a blackhole and provides a graphical user interface for management and monitoring. It is for people who want to keep online ads from appearing and prefer a GUI for controlling and observing the blocker. Through that interface, users can manage Pi-hole and monitor its advertisement-blocking role instead of working only with the blackhole function itself. The program has a focused purpose: it handles Internet advertisements, while its GUI is devoted to management and monitoring. This narrow scope is its main limitation. People looking for functions unrelated to advertisement blocking will need a different program. Pi-hole is best matched to users whose central requirement is an ad blackhole with graphical oversight, not a general tool for other Internet tasks.
