About:
Zen is an open-source ad-blocker and privacy guard designed to protect user data and browsing experience. It functions as a DNS sinkhole and network filter to block trackers, ads, and malicious domains across your entire system. The tool emphasizes transparency and local control, keeping your traffic private without relying on third-party services.
Key Features:
  • Blocks ads, trackers, and malware at the network level
  • Privacy-first with no telemetry or external data collection
  • Lightweight and fast with minimal system resource usage
  • Simple command-line interface for easy management
  • Open-source and community-driven
Use Cases:
  • Enhancing privacy and security for all devices on a network
  • Removing advertisements and trackers from web browsing
  • Protecting against malware and phishing domains
Alternatives:
  • NextDNS – Cloud-based service vs Zen's local, offline-first approach
  • Pi-hole – Requires dedicated hardware/server vs Zen's lightweight, single-machine installation
  • AdGuard – Commercial product vs Zen's fully open-source and free model
