AdGuard Home is the clearest directly documented Pi-hole alternative for a self-hosted home network. Both products use DNS sinkholing: devices ask a local DNS server to resolve domain names, and the server refuses requests for domains on blocklists. AdGuard Home’s project documentation lists encrypted DNS upstreams, DNS-over-HTTPS and DNS-over-TLS server modes, parental controls, Safe Search, per-client settings and cross-platform packages as differences in its own comparison. Pi-hole, meanwhile, offers mature household controls such as client groups, query logs, regular-expression allow/deny rules, an optional DHCP server and a REST API.
The important qualification is that neither product is a universal browser-style content blocker. Every phone, computer, television or console must actually use the filtering server for DNS, and DNS sinkholing cannot inspect page elements or scripts the way a traditional ad-blocking extension can. Choose between Pi-hole and AdGuard Home according to your network’s DHCP options, the host you can run, the per-device controls you need, and whether encrypted DNS features belong in your design.

What “network-wide ad blocking” actually means
Pi-hole describes itself as a DNS sinkhole that protects devices without installing client software. In practical terms, your router or individual devices send DNS questions—such as a request to resolve an advertising or tracking domain—to the filtering server. If that domain matches a blocklist, the server returns a blocked response instead of the destination address. The browser, app or smart-TV service then cannot connect to that particular hostname.

“DNS sinkholing is capable of blocking a big percentage of ads, but it lacks the flexibility and the power of traditional ad blockers.” — AdGuard Team, AdGuard Home project README
That limitation explains why a DNS service may not remove every advert, sponsored element or in-app promotion. A page can load an advert from the same domain as its legitimate content, or an application can use a hard-coded address instead of asking your DNS server. Network-wide DNS filtering is best understood as a broad first layer, not a replacement for every browser or app-level control.
Coverage is therefore a configuration result. A correctly installed server that no client uses blocks nothing for that client. Conversely, sending DNS for a whole household through one resolver gives you a single place to review queries and apply rules.

Before comparing alternatives, identify the Pi-hole functions your household already depends on. The project’s official site and documentation describe several useful controls:
- Client groups: assign devices to groups with different blocking policies. A child’s tablet, a work laptop and an entertainment device do not have to share identical rules.
- Query logs: inspect DNS requests to see which domains clients are asking for and whether a blocklist decision is affecting an application.
- Allow and deny rules: use regular expressions as well as ordinary entries when a domain needs an exception or an additional block.
- Optional DHCP service: if your router cannot tell clients to use Pi-hole for DNS, Pi-hole can provide DHCP after the router’s own DHCP service is disabled.
- REST API: integrate status or query information with other household tooling.
Pi-hole is software rather than a required appliance. Its overview lists a Raspberry Pi, an old PC, a virtual machine and a NAS as possible hosts. That lets you reuse equipment you already operate instead of buying a dedicated box. The official overview is at Pi-hole Documentation, and the project site’s feature description is at Network-wide Ad Blocking.
AdGuard Home: the closest self-hosted alternative
AdGuard Home’s project documentation explicitly compares it with Pi-hole and says both products block ads and trackers through customizable DNS sinkholing. In that project-maintained comparison, AdGuard Home adds several capabilities that matter when you want more than basic blocklists:

The following table separates documented capabilities from the practical decision they create. “Not stated” means the supplied official material does not establish an equivalent value; it is not evidence that a feature is absent.
| Decision area | Pi-hole | AdGuard Home | What it means at home |
|---|---|---|---|
| Filtering method | DNS sinkholing | DNS sinkholing | Both need client DNS traffic to pass through the filtering server and neither is a universal page-element blocker. |
| Per-device policy | Client groups with different rules | Per-client configuration listed in AdGuard’s comparison | Either can separate household policies; map your devices deliberately rather than using one rule set for everyone. |
| Logging and investigation | Query logs documented | Not stated in the supplied comparison | Pi-hole’s logs are a documented troubleshooting and visibility feature. Confirm the exact logging controls you need before switching. |
| Custom exceptions | Allow/deny rules, including regular expressions | Customizable blocking is documented; equivalent regex detail not stated | Pi-hole documents the specific regex workflow. Check AdGuard Home’s current interface if complex pattern rules are essential. |
| Encrypted upstream DNS | Not stated in the supplied Pi-hole materials | Listed as a built-in difference in AdGuard’s comparison | AdGuard Home is the better-documented fit when the resolver-to-upstream link must use encryption. |
| Encrypted DNS server modes | Not stated | DNS-over-HTTPS and DNS-over-TLS server operation listed | Useful for clients that can be configured for encrypted DNS; it does not remove the need for correct network routing. |
| Parental controls and Safe Search | Not stated | Adult-domain blocking and Safe Search listed | AdGuard Home has the clearer documented path for these controls. |
| DHCP fallback | Built-in DHCP server documented | Not stated in the supplied material | Pi-hole has a documented option when the router cannot distribute a custom DNS server. |
| Automation interface | REST API documented | Not stated | Pi-hole is the documented choice if an existing dashboard or script depends on that API. |
| Host choices | Raspberry Pi, old PC, VM or NAS listed | Release binaries, official Docker image and official Snap package | Both can fit an existing server; select the installation format your operating system can maintain. |
Choose the right architecture before installing
Use a self-hosted resolver when local control is the priority
A self-hosted Pi-hole or AdGuard Home instance keeps policy management inside your network. You decide which lists and exceptions to use, can inspect local DNS activity according to the product’s logging controls, and do not have to redirect every device to a third-party cloud account. The trade-off is operational responsibility: the host, its updates, its storage and its network reachability become your job.
Consider a managed DNS service only when you accept cloud administration
A cloud-managed DNS provider can avoid running a local host, but current plan features, prices and availability are not established here. Do not select one on assumptions about retention, encryption, parental controls or regional performance. Verify those points in the provider’s current documentation before replacing a local resolver.
Match the host to your maintenance habits
Pi-hole’s documented host list includes a Raspberry Pi, an old PC, a virtual machine and a NAS. AdGuard Home offers release binaries and official Docker and Snap packages. A small always-on computer is convenient, while a VM or container may be easier to back up and redeploy if you already maintain a server. The best host is the one that remains powered, receives updates and can be repaired without taking the rest of the network offline.
Configure Pi-hole so every device uses it
Installation alone does not provide network-wide coverage. Pi-hole’s post-install guidance puts DNS distribution at the center of the setup.
- Install Pi-hole on a reachable host. Use a Raspberry Pi, old PC, VM or NAS that can remain available to the household network. Give it a stable address through your network’s normal address-management method so the router’s DNS setting will not drift.
- Open the router’s DHCP settings. In the router administration interface, find the LAN or DHCP section and set the DNS server handed to clients to the Pi-hole address. The exact label varies by router firmware; look for “DNS server,” “local DNS” or a similar field.
- Renew client leases. Reconnect Wi-Fi, renew the DHCP lease, or restart devices so they receive the new DNS value. A device retaining an old lease can continue using the previous resolver and appear to bypass Pi-hole.
- Confirm a query arrives. Open Pi-hole’s query log while loading a few sites or launching an application. The client should appear with requests and block decisions. If it does not, inspect the client’s actual DNS configuration rather than changing blocklists first.
- Use Pi-hole DHCP only when necessary. If the router cannot distribute a custom DNS server, disable the router’s DHCP service first, then enable Pi-hole’s built-in DHCP server and configure the LAN range there. Running two DHCP servers on one network can hand out conflicting gateways and DNS addresses.
- Treat manual device DNS as a last resort. Entering the Pi-hole address separately on every phone, computer, television and console is harder to maintain and will not automatically cover new devices or guests.
Pi-hole’s complete post-install guidance, including the DHCP fallback and the failure warning, is at Post-Install.
Install AdGuard Home with the documented ports in mind
AdGuard Home’s getting-started guide provides three supported distribution paths: release binaries, an official Docker image and an official Snap package. Choose one that matches the operating system you already patch and back up.
- Prepare a host. Use an always-on machine or server with a network address that clients can reach. If you use Docker or Snap, install and update that packaging system according to its normal administrative process.
- Reserve the initial setup port. On first start, AdGuard Home uses TCP port 3000 for its setup wizard. Make sure the host firewall and any container port mapping expose that port only as needed for the initial configuration.
- Complete the web-interface setup. The guide identifies TCP port 80 for the web interface. Choose the listening address and administrative credentials in the wizard, then restrict access to your trusted LAN where your deployment allows it.
- Expose DNS. AdGuard Home needs UDP port 53 for ordinary DNS. Map or allow that port on the host and, for a container, publish it on the LAN address clients will use. Other protocols can require additional ports.
- Check firewall rules. The official guide specifically recommends reviewing firewall settings. A service can be running locally yet unreachable from another VLAN, Wi-Fi network or container bridge if those paths are blocked.
- Point DHCP at AdGuard Home. Set the router’s DHCP-provided DNS address to the AdGuard Home host, then renew leases and verify that client queries appear in its interface.
Port numbers and installation options are documented in Getting started with AdGuard Home. If you later enable encrypted DNS server modes, follow the product’s current documentation for the additional listeners and certificates required; do not assume that opening only UDP 53 enables those protocols.

Build useful household policies without breaking devices
Start with a small exception workflow
When an application stops working, inspect the DNS log first. Identify the blocked hostname, add the narrowest allow rule that restores the function, and retest. Pi-hole documents ordinary allow/deny entries and regular-expression rules; broad wildcard exceptions can re-enable more advertising and tracking domains than intended. Record why an exception exists so another household administrator can remove it later.

Separate clients by role
Use Pi-hole client groups or AdGuard Home’s documented per-client settings to avoid forcing one policy on every device. A work computer may need fewer aggressive blocks than a children’s tablet; a streaming box may need a different exception from a phone. Name clients consistently, and check that privacy features such as randomized Wi-Fi addresses have not created multiple unidentified entries.
Use Safe Search and adult-domain controls deliberately
AdGuard Home lists adult-domain blocking and Safe Search among its built-in differences. Treat these as policy controls, not guarantees of age-appropriate content: DNS filtering covers domains, while content can also be hosted under mixed-use domains or delivered inside an application. Explain to household users what the setting does and does not enforce.
Review logs with a privacy purpose
DNS logs can reveal which services people use, not just which adverts were blocked. Restrict administrative access, choose retention that fits your household, and avoid exporting logs unnecessarily. Pi-hole’s query-log feature is documented; AdGuard Home’s exact logging controls should be checked in the version you deploy.

Plan for failure before changing the router
Pi-hole warns that a host configured to use Pi-hole as its own DNS resolver can lose DNS resolution when the Pi-hole service fails. That creates a particularly awkward recovery loop: the machine may need internet access to download a fix, yet its resolver is the service that is down.
- Keep local access available. Know the host’s LAN address, administrator credentials and how to reach its console or shell without DNS.
- Document the router’s original DNS settings. Write down the previous values before replacing them so you can restore ordinary resolution quickly.
- Know the DHCP control point. Record whether the router or Pi-hole supplies DHCP. If Pi-hole is the DHCP server, disabling it without restoring another DHCP service can leave clients without addresses.
- Test a rollback. From a client, temporarily assign a known working resolver or restore the router’s previous DNS setting, then verify that ordinary internet access returns. Reapply the filtering address only after the host is healthy.
- Back up policy data. Keep copies of custom allow/deny entries and client assignments so a reinstall does not require reconstructing household rules from memory.
A second filtering host can improve availability, but the supplied documentation does not define a particular redundancy design. If you build one, test which resolver your router distributes, how clients fail over, and whether both servers carry the same policy before relying on it.

Troubleshoot by symptom
No clients appear in the query log
- Check the client’s current DNS address; many operating systems display it in network details.
- Renew the DHCP lease or reconnect to Wi-Fi.
- Look for a browser, VPN or security application that supplies its own encrypted DNS endpoint.
- Confirm that the router’s DHCP setting points to the filtering host and that the host address has not changed.
Only some devices are filtered
Those devices may have static DNS settings, an old lease, a separate guest network or a different VLAN. Correct the DHCP scope for that segment, or configure the device explicitly. Manual settings should be treated as exceptions because they must be maintained when the server address changes.
A website or app breaks after enabling a list
- Use the DNS log to find the blocked hostname associated with the failure.
- Allow that specific hostname temporarily.
- Retest the feature, then narrow the rule or remove the offending list if the exception is too broad.
- Record the decision in your household policy notes.
The filtering host has internet access problems
If the host uses itself for DNS, switch its resolver temporarily through a local console or restore the router’s previous DNS distribution. Once name resolution works, update or repair the filtering service, then return clients to it and verify queries.
AdGuard Home’s setup page will not open
During first start, check that TCP port 3000 is reachable for the wizard and that TCP port 80 is available for the web interface. Review host, router and container firewall rules, and ensure another web service is not already occupying those ports. DNS itself requires UDP 53; exposing only the web ports will not make clients resolve through AdGuard Home.
Security and privacy decisions
DNS filtering concentrates visibility and control in one service. Protect the administration interface with strong credentials, limit it to trusted network segments, and keep the host and its packaging method updated. Do not expose the management interface or DNS service directly to the public internet unless you have a specific, documented design for authentication, encryption and abuse prevention.
Encrypted upstream DNS can protect the connection between AdGuard Home and its upstream resolver, while DNS-over-HTTPS or DNS-over-TLS server modes can protect supported client connections to AdGuard Home. These features address transport confidentiality; they do not make the blocklists correct automatically, hide the existence of a local DNS server from every network observer, or turn DNS filtering into a content-inspection engine. Confirm which links in your path are encrypted and what the chosen upstream provider retains.
Which option fits which household?
| If your priority is… | Start with… | Reason |
|---|---|---|
| A documented DHCP fallback when the router cannot distribute custom DNS | Pi-hole | Its official post-install guide documents an optional DHCP server, with the router DHCP service disabled first. |
| Encrypted upstream DNS and encrypted DNS server modes | AdGuard Home | Those capabilities are listed in AdGuard’s own Pi-hole comparison. |
| Client groups, query logs, regex rules and a REST API | Pi-hole | These household-management features are documented by the Pi-hole project. |
| Docker or Snap deployment | AdGuard Home | The official getting-started guide offers an official Docker image and Snap package, as well as binaries. |
| The smallest operational footprint | Whichever host you already maintain | Pi-hole can run on several existing host types, while AdGuard Home supports multiple packaging paths; maintenance fit matters more than buying a particular device. |
| A guaranteed replacement for browser extensions | Neither | Both use DNS sinkholing, which the projects themselves distinguish from traditional ad blockers. |
Bottom line: choose by network fit, not by blocklist promises
AdGuard Home is the strongest directly documented Pi-hole alternative when encrypted DNS, Safe Search, adult-domain controls, per-client settings or containerized deployment are decisive. Pi-hole remains the better-documented fit for households that rely on client groups, query logs, regular-expression rules, its REST API or its built-in DHCP fallback. In either case, success depends on making every relevant DHCP scope—or carefully chosen individual device—use the filtering server, and on having a recovery path for the day that server stops answering DNS.
