Pi-hole vs AdGuard — What They Actually Are
Pi-hole is a DNS sinkhole that has been around since 2014. It runs on a device you own — most commonly a Raspberry Pi — and acts as your network's DNS server. When any device on your network asks "where is analytics.example.com," Pi-hole checks the domain against a blocklist. If it is a known ad or tracking domain, Pi-hole returns a blank response and the connection is never made. The software is open source, community-driven, and has a huge library of community-maintained blocklists. AdGuard is, confusingly, two separate products. AdGuard Home is the self-hosted DNS blocker — the direct competitor to Pi-hole. It is also free and open source, built by the same company that makes the AdGuard browser extension. It installs as a single binary on Linux, macOS, Windows, FreeBSD, or as a Docker container. When people say "Pi-hole vs AdGuard" they almost always mean Pi-hole vs AdGuard Home. AdGuard also sells a commercial AdGuard DNS service (cloud-based, no hardware) and AdGuard desktop/mobile apps, but those are separate products. Both Pi-hole and AdGuard Home do the same fundamental thing — block domains at the DNS layer before your devices can connect to them. The differences show up in features, polish, and philosophy.
Core Differences: Features, Interface, Encrypted DNS
The single biggest difference is encrypted DNS. AdGuard Home supports DNS-over-HTTPS, DNS-over-TLS, and DNS-over-QUIC out of the box. You flip a switch in the web UI and your devices can talk to AdGuard Home over encrypted DNS. Pi-hole supports none of these natively. To get encrypted DNS with Pi-hole, you install cloudflared or Unbound alongside it and configure them to chain together. It works, but it is an extra thing to maintain and an extra failure point. The admin interface is where AdGuard Home pulls ahead visually. Pi-hole's dashboard has barely changed in a decade — it is functional but dated. AdGuard Home's UI is modern, organised, and the setup wizard walks you through everything on first launch including blocklists, upstream DNS, and encryption. Pi-hole's setup is all command-line. Filtering features are more flexible in AdGuard Home. It supports AdGuard-style syntax (closer to uBlock rules), regex, CNAME cloaking detection, and parental controls and safe-search enforcement are built in. Pi-hole supports hosts-format blocklists and basic regex. Both can block the same domains — AdGuard Home can just express more complex rules without extra tooling. Performance on modern hardware is a wash. Both handle tens of thousands of queries per second. Both have negligible CPU and memory footprints on a Raspberry Pi 4 or an old mini PC. If you are querying at scale — thousands of devices, a small office — both scale fine with proper hardware.
Setup Complexity: Which One Is Easier?
If you have never used Linux: AdGuard Home wins by a mile. A single binary, a built-in web setup wizard, and no follow-up configuration needed to get encrypted DNS working. Most users are up and running in 10 minutes including flashing an SD card for a Pi. If you are comfortable with a terminal: both are roughly equal. Pi-hole's `curl | bash` installer is famously simple. AdGuard Home has a comparable install command. Both require you to then point your router's DNS settings at the new server — this is the step that trips up most people, regardless of which tool they chose. Ongoing maintenance is where Pi-hole feels heavier. Encrypted DNS requires Unbound or cloudflared running alongside. Updating blocklists is manual unless you set up a cron job. Recovery after an SD card dies or a bad update means re-running the installer and restoring a config backup. AdGuard Home handles updates through the UI, auto-schedules blocklist refreshes, and has a cleaner backup/restore workflow. Neither tool is truly "set it and forget it." You are running a DNS server. When it breaks, your whole network loses the internet until you fix it or switch DNS. Plan for that — either run a fallback resolver configured on your router, or be ready to roll back quickly.
Cost, Privacy & What Most People Overlook
Both Pi-hole and AdGuard Home are free and open source. There is no subscription, no feature gating, no "pro" tier. The real cost is hardware and time. A Raspberry Pi 5 with an SD card is around 75 euros. If you already run a home server, NAS, or mini PC, the cost is zero — you add a container. The hidden cost is time. Two to four hours for initial setup if everything goes smoothly, plus occasional maintenance when blocklists change, a software update breaks something, or a new tracking technique requires you to add a new blocklist. For most hobbyists this is fun; for most mainstream users it is a burden they abandon after a month. On privacy: both tools keep all DNS queries local. Nothing leaves your network unless you configure upstream DNS resolvers that you do not trust. This is their biggest advantage over cloud services like NextDNS or Cloudflare — no third party sees your query history by default. However, this only holds if you actually configure things correctly. Both tools default to using Google or Cloudflare as upstream resolvers out of the box, which means those companies see your queries unless you change it. If privacy is your primary goal: use Quad9, your ISP's DNS, or a DoT/DoH resolver you trust as the upstream in either tool.
Why Pi-hole & AdGuard Both Fail on Mac — and What to Add
Here is the part nobody running Pi-hole or AdGuard Home wants to admit: neither tool can tell you which app on your Mac is making a connection. Both operate at the DNS layer, which only sees "some device on the network asked for analytics.example.com." Was it your browser? A background updater? Zoom phoning home? Spotify's telemetry? At the DNS layer, you cannot tell. This matters more on macOS than people realise. A typical Mac has 40+ background processes each making connections — iCloud, Spotlight suggestions, Maps, Photos, News, every Adobe and Microsoft product, every Electron app, every crash reporter. DNS blocking catches the ones that use known tracker domains. It catches none of the ones that phone home to their own first-party servers. And if an app uses hardcoded IP addresses instead of domain names — which some do specifically to bypass DNS filtering — your DNS blocker sees nothing at all. The fix is pairing DNS-level blocking with application-level control. NetMute runs on your Mac and shows you exactly which app made which connection, to which domain, how often. It blocks 624+ known trackers automatically but — more importantly — it lets you see when a specific app is quietly sending data somewhere and block that specific app, not the whole domain for the whole network. The ideal setup in 2026: Pi-hole or AdGuard Home at the network edge to block ads and trackers across every device (smart TVs, phones, IoT), plus NetMute on each Mac for per-app visibility and control. DNS blocking is broad coverage. Per-app firewalling is targeted depth. You need both. NetMute is 9.99 euros one-time, no subscription, no account. Pair it with whichever DNS blocker you pick and you have a layered privacy setup that catches what DNS alone misses.
