Pi-hole vs AdGuard Home vs NextDNS

Pi-hole, AdGuard Home, and NextDNS all block the same ad/tracker domains from the same public lists. The real differences are where they run, how they handle encrypted DNS and devices that leave the house, and how much you want to operate yourself.

Who this is for

Home operators deciding how to do network-wide DNS filtering in 2026 — choosing between self-hosting Pi-hole, self-hosting AdGuard Home, or using cloud-hosted NextDNS — and who want the honest trade-offs rather than a 'best blocker' listicle.

Outcome

A clear, evidence-based pick that matches your operating model: whether you want zero hardware and filtering on devices that leave the house, the fewest self-hosted moving parts with built-in encrypted DNS, or maximum control and ecosystem — with realistic expectations of what DNS filtering can and cannot block.

Required inputs

  • An honest read of how much you want to operate yourself (patching, backups, an always-on box) versus pay a small fee for someone else to run it.
  • Whether you need filtering on mobile devices when they're off your home network (cellular / other Wi-Fi).
  • A rough sense of your household's monthly DNS query volume (matters for the NextDNS free tier) and whether you care about encrypted DNS upstream.
  • Where a self-hosted resolver would live (Raspberry Pi, NAS container, mini-PC) if you go that route.

Step-by-step procedure

1

Decide self-hosted vs cloud first

Do: Answer one question: do you want to run and maintain a box, or not? Self-hosted (Pi-hole/AdGuard Home) gives local control and no per-query limits but is yours to patch and back up. Cloud (NextDNS) is nothing to run and filters devices anywhere, at the cost of a query cap on the free tier and trusting a provider.

Expected result: You've narrowed to either the two self-hosted options or NextDNS.

If not: If you can't run an always-on box reliably (no NAS/Pi, frequent power loss), lean cloud — a self-hosted resolver that's down takes all DNS with it.

2

If self-hosting, choose Pi-hole vs AdGuard Home on operating model

Do: Pick AdGuard Home if you want one binary with built-in DHCP and native encrypted DNS (DoH/DoT/DoQ) as upstream and server, and the fewest parts. Pick Pi-hole if you want deeper group/regex control, a large ecosystem, and you'll pair it with Unbound for recursive resolution. Remember both block identically from the same lists.

Expected result: You've chosen based on parts-count vs control, not on imagined 'blocking power'.

If not: If you find yourself comparing blocklist sizes to decide, stop — that's not the differentiator; the operating model is.

3

If cloud, size the NextDNS free tier honestly

Do: Estimate household query volume. The NextDNS free tier filters up to 300,000 queries/month, then degrades to a plain resolver (no filtering/logging) until the month resets. A small household may stay under it; a busy multi-device home won't.

Expected result: You know whether you'll live within the free tier or should budget for the paid plan.

If not: If you can't estimate, run NextDNS free for a month and watch the query counter before committing.

4

Plan for off-network and encrypted DNS

Do: If you need filtering on phones away from home, NextDNS does it natively via device profiles; with Pi-hole/AdGuard Home you'd route the phone home over a mesh VPN (Tailscale/WireGuard) and use the resolver's tailnet IP. Decide how you'll handle encrypted DNS (AdGuard Home does it natively; Pi-hole pairs with Unbound or a DoH proxy).

Expected result: Your choice covers both home and away, and your stance on encrypted upstream DNS is settled.

If not: If off-network filtering matters and you don't want a VPN, that pushes you toward NextDNS.

5

Set expectations and commit

Do: Confirm what none of them fix: first-party/CDN ads (YouTube, most in-app ads) and traffic carried by VPN/iCloud Private Relay. Then commit to one and implement it — for self-hosted, follow force every device through it so the choice actually takes effect.

Expected result: You've picked one with realistic expectations and a plan to enforce it network-wide.

If not: If you're choosing one to 'finally block YouTube ads', reset expectations first — no DNS filter does that reliably.

Commands and settings paths

Confirm any choice is actually in the path

nslookup pi.hole (self-hosted) • check the NextDNS 'Setup' test page (cloud)

Where: On a client after pointing DNS at the chosen resolver.

Expected: The self-hosted resolver answers, or the NextDNS test page confirms your profile is linked.

Failure means: If the test fails, clients aren't using the resolver yet — DHCP/IPv6/DoH still needs sorting.

Safe next step: Work through the force-every-device guide before judging the filter's effectiveness.

Sanity-check blocking parity

Look up a known tracker domain through each candidate resolver

Where: From a test client, switching the resolver between candidates.

Expected: All candidates block the same tracker domain (same lists → same result).

Failure means: A difference usually reflects which blocklists you enabled, not an inherent capability gap.

Safe next step: Decide on operating model, not on a contrived block-count comparison.

Evidence to record

  • Your decision and the single reason that drove it (operating model / off-network need / query volume).
  • Current versions of whatever you chose, date-stamped (these move — confirm against the project's releases).
  • For NextDNS: your observed monthly query count vs the 300,000 free-tier threshold.
  • What you explicitly accept it won't block (first-party ads, Private Relay/VPN traffic).

Common mistakes

  • Choosing on blocklist size or 'blocking power' — Pi-hole and AdGuard Home block identically from the same lists.
  • Self-hosting on hardware that isn't reliably on — a resolver that's down takes all DNS with it; have a fallback.
  • Assuming the NextDNS free tier is unlimited — it filters up to 300k queries/month, then degrades to a plain resolver.
  • Expecting any of them to block YouTube/first-party ads or VPN/Private Relay traffic — they can't.

Stop points

  • Stop before self-hosting if you can't commit to patching and a power-loss fallback — cloud filtering may serve you better.
  • Stop before paying for NextDNS until you've confirmed your real monthly query volume exceeds the free tier.
