Overview: Two Heavyweights in Network-Wide Ad Blocking

If you want to block ads and trackers across your entire home network — every device, every app, no client-side extension required — Pi-hole and AdGuard Home are the two dominant solutions. Both run on a Raspberry Pi or any Linux server and act as a local DNS resolver. But they differ in meaningful ways.

Quick Comparison Table

Feature Pi-hole AdGuard Home
Initial Setup Difficulty Moderate Easy
Web UI Quality Good Excellent
Built-in DoH/DoT Support Via workaround (cloudflared) Native, built-in
HTTPS Filtering No Yes (with cert)
Per-Client Rules Limited Robust
Filter List Ecosystem Very large (community) Large (growing)
Resource Usage Low Low–Moderate
Active Development Yes Yes (very active)

Pi-hole: The Community Classic

Pi-hole has been around since 2014 and has a massive, battle-tested community behind it. It works as a DNS sinkhole — returning empty responses for known ad and tracker domains.

Strengths

  • Enormous collection of community blocklists and documentation.
  • Lightweight — runs comfortably on a first-generation Raspberry Pi Zero.
  • Deep integration with dnsmasq for advanced local DNS configuration.
  • Gravity system makes updating blocklists simple.

Weaknesses

  • Native DoH/DoT requires installing a separate tool like cloudflared or unbound.
  • Per-client rules and group management added later — less polished than AdGuard.
  • The web interface, while functional, feels dated compared to AdGuard Home.

AdGuard Home: The Modern Challenger

AdGuard Home launched in 2019 as an open-source project from the team behind the commercial AdGuard product. It was designed from the ground up with modern privacy features in mind.

Strengths

  • Built-in DNS-over-HTTPS, DNS-over-TLS, and DNSCrypt support — no extra tools needed.
  • Polished, modern web interface with real-time query logs.
  • Per-client and per-device blocking rules are first-class features.
  • Supports both DNS blocklists and URL-style filter rules (similar to uBlock Origin).

Weaknesses

  • Slightly higher memory footprint than Pi-hole.
  • Community is smaller, though growing quickly.
  • Some advanced dnsmasq features require more configuration effort.

Which Should You Choose?

The right choice depends on your priorities:

  • Choose Pi-hole if you want the most community resources, maximum filter list options, and are comfortable with light terminal work.
  • Choose AdGuard Home if you want an easier setup experience, built-in DoH/DoT out of the box, and a cleaner modern dashboard.
  • Use both together? Some advanced users run Pi-hole as the LAN-facing DNS and route its upstream queries through AdGuard Home for layered filtering — though this adds complexity.

Bottom Line

Both tools are excellent and free. AdGuard Home has a slight edge for newcomers thanks to its polished UI and native encrypted DNS. Pi-hole remains the go-to for power users and those who value the depth of its community ecosystem. Either way, you'll dramatically reduce ads and trackers across your entire network.
