Pi-hole vs AdGuard Home: Beginner’s Guide
For beginners, AdGuard Home is the better network ad blocker because it is easier to install, configure, and maintain than Pi-hole. Pi-hole offers more customization and a longer history, but AdGuard Home provides a more user-friendly interface and built-in encryption options that simplify setup. This guide compares both tools to help you decide which one fits your needs.
Background: What Are Pi-hole and AdGuard Home?
Pi-hole and AdGuard Home are both network-wide ad blockers that work at the DNS (Domain Name System) level. Instead of blocking ads on a single device, they filter traffic for every device on your network—smart TVs, phones, laptops, and IoT gadgets. They do this by acting as a DNS server: when a device asks for a website’s IP address, the blocker checks the domain against a blocklist and returns a “blocked” response if it matches.
Pi-hole started in 2015 as a Raspberry Pi project and has grown into a popular open-source tool with a large community. AdGuard Home is a newer project from the AdGuard team, first released in 2018, and is also open-source. Both are free to use and can run on a Raspberry Pi, a Linux server, or even a Docker container.
How They Work: DNS Filtering Explained
When you type a website address into your browser, your device sends a DNS query to a resolver (like your ISP’s server) to find the IP address. Pi-hole and AdGuard Home intercept these queries and compare the domain against a list of known ad and tracker domains. If there’s a match, they respond with a blocked IP (often 0.0.0.0), so the ad content never loads.
Both tools allow you to add blocklists from third-party sources, such as StevenBlack’s hosts file or OISD. You can also whitelist domains that get incorrectly blocked. The key difference is that AdGuard Home has a built-in DNS-over-HTTPS (DoH) and DNS-over-TLS (DoT) server, so you can encrypt your DNS traffic without setting up a separate proxy. Pi-hole requires additional software like cloudflared or dnscrypt-proxy to achieve the same.
Installation and Setup: Which Is Easier?
For a beginner, AdGuard Home is generally easier to install. It provides a single binary file that you download and run, and then you access a web-based setup wizard. The wizard guides you through choosing a port, setting up a username/password, and configuring upstream DNS servers. Pi-hole, on the other hand, uses a command-line installer script that asks you a series of questions. While the script is straightforward, it can be intimidating if you’re not comfortable with the terminal.
Here’s a quick comparison of the installation steps:
- Pi-hole: Download the installer, run it, choose network interface, set upstream DNS, pick blocklists, and set a password. Requires root access.
- AdGuard Home: Download the binary, run it, open the web wizard, set the port, create an admin account, and choose upstream DNS. No root required if you use a non-privileged port.
Both can run on a Raspberry Pi, but AdGuard Home also offers pre-built packages for Windows and macOS, which Pi-hole does not natively support (though you can run it in a VM or Docker).
User Interface and Daily Use
AdGuard Home’s web dashboard is modern and intuitive, with a clean layout that shows query statistics, top clients, and recent queries. It includes a built-in query log with filters and a whitelist/blacklist manager that is easy to navigate. Pi-hole’s dashboard is functional but more basic, with a dark theme and a simple list of stats. It also has a long-standing web interface that some users find dated.
For daily tasks like checking blocked queries or adding a domain to the whitelist, AdGuard Home is more straightforward because it uses a searchable table and inline actions. Pi-hole requires you to navigate to separate pages for whitelisting and blacklisting, and the query log is less user-friendly. If you’re not a tinkerer, AdGuard Home’s interface will feel less intimidating.
Performance and Resource Usage
Both tools are lightweight and can run on a Raspberry Pi Zero 2 W or an old PC. Pi-hole uses slightly less RAM because it’s written in C and shell scripts, while AdGuard Home is written in Go, which has a bit higher memory footprint. In practice, the difference is negligible on modern hardware—both use under 100 MB of RAM with standard blocklists.
However, AdGuard Home has a built-in cache that can be tuned, and it supports parallel query processing, which can speed up DNS responses. Pi-hole relies on the upstream DNS resolver’s cache, but it also has a cache option. For most home networks, both will feel equally fast.
Common Problems and How to Solve Them
One common issue with both tools is that some devices (like Chromecast or certain smart TVs) may ignore the router’s DNS settings and use their own. To fix this, you need to configure your router to force DNS redirection (if supported) or set the DNS on each device manually. Another issue is false positives—legitimate domains getting blocked. Both tools allow you to whitelist domains, but AdGuard Home’s per-client whitelist is more flexible.
If you experience slow internet after installing, check that you haven’t accidentally blocked a critical domain like a CDN. You can temporarily disable the blocker to test. Also, if you use a VPN on your phone, it may bypass the DNS filter; you’ll need to configure the VPN to use the same DNS server.
Cost and Hardware Requirements
Both Pi-hole and AdGuard Home are completely free and open-source. You only need to pay for the hardware to run them. A Raspberry Pi 4 (around $35) is more than enough, but you can also use an old laptop or a cloud server. If you already have a server running other services, you can install AdGuard Home as a Docker container with a single command. Pi-hole also has a Docker image, but the setup is slightly more involved.
There are no subscription fees or hidden costs. The only ongoing cost is electricity, which for a Raspberry Pi is about $5 per year.
Safety and Privacy Considerations
Both tools are safe to use, but they can see all your DNS queries, which means they know every domain you visit. This is a privacy concern if you don’t trust the software or the device it runs on. Since both are open-source, you can inspect the code, but the average user won’t do that. AdGuard Home has a privacy policy that states it does not collect data, but you are still running it on your own hardware, so the data stays with you.
Another consideration: if you use a public DNS service like Cloudflare or Google, you are already sending your queries to them. With Pi-hole or AdGuard Home, you can choose to use an encrypted upstream (DoH/DoT) to protect your DNS traffic from eavesdropping. AdGuard Home makes this easier with built-in support, while Pi-hole requires extra setup.
Frequently Asked Questions
Can I run both Pi-hole and AdGuard Home at the same time? Yes, you can run them on different devices or in different Docker containers, but they would both try to answer DNS queries. It’s not useful to run both on the same network unless you want redundancy. In that case, you can configure one as the primary and the other as a secondary DNS server.
Which one has better blocking accuracy? Both use the same blocklists, so accuracy is similar. However, AdGuard Home’s default blocklist is slightly more aggressive and may block more trackers. You can customize either to your liking.
Will these block ads on YouTube or Netflix? No, because those ads are served from the same domain as the video content. DNS-based blockers cannot distinguish between the ad and the video. You would need a browser extension or a proxy-based blocker for that.
Can I use them on a Windows PC without a Raspberry Pi? AdGuard Home has a native Windows version, so you can run it directly on your PC. Pi-hole does not have a native Windows version, but you can use the Windows Subsystem for Linux (WSL) or a virtual machine.
Do I need to change my router’s DNS settings? Yes, to make the filter work network-wide, you need to set your router’s DNS to the IP address of the Pi-hole or AdGuard Home device. Alternatively, you can set the DNS on each device manually.
Which is better for a complete beginner? AdGuard Home is better because of its easier installation and more intuitive interface. Pi-hole is better if you enjoy tinkering and want more control over every aspect.
