AdGuard Home

AdGuard Home runs as a DNS server that intercepts requests to known advertising and tracking domains and redirects them to a null destination, preventing those connections for all devices on a network. By configuring routers or individual devices to use its DNS service, users obtain network‑wide privacy protection without installing client‑side blockers. The software is available for Windows, macOS, Linux, and other Unix‑like systems, and can be deployed via automated scripts, manual setup, or container images.

The project targets home users, small offices, and anyone who wants a centralized, self‑hosted solution for ad and tracker filtering. Because it is open‑source under GPL‑3.0 and requires no subscription, it appeals to those who prefer freely available, community‑maintained tools. Documentation includes installation guides, an API, and comparison pages to help users assess its fit against public DNS filters or other self‑hosted options.

Key distinguishing aspects are its network‑wide scope, the ability to run on a variety of operating systems, and the fact that it shares code with the public AdGuard DNS service while remaining fully self‑hosted and configurable. The codebase is written in Go, includes test coverage metrics, and is actively maintained with regular releases.
