Why Compare DNS Filters?
DNS filtering is one of the most effective ways to block ads, trackers, malware, and phishing across every device on your network — without installing software on each one. But the options range from self-hosted open-source projects to cloud-managed services, each with different trade-offs in setup complexity, privacy, features, and cost.
This article compares five of the most popular DNS filtering solutions: VeloGuardian DNS, Pi-hole, AdGuard Home, NextDNS, and Cloudflare 1.1.1.1 for Families. The goal is to help you choose the right one for your needs.
The Contenders
VeloGuardian DNS is a free, self-hosted DNS filtering appliance distributed as a hardened OVA (Open Virtual Appliance). Import it into VMware, VirtualBox, or Proxmox and it's ready to filter DNS queries with a pre-configured web dashboard, automatic blocklist updates, and a locked-down operating system. Designed for home users, families, and small businesses.
Pi-hole is the most well-known self-hosted DNS filter. It's an open-source project that runs on Linux — typically a Raspberry Pi, though any Linux system works. It provides a web dashboard for managing blocklists and viewing query logs. Pi-hole requires manual installation, OS setup, and ongoing maintenance.
AdGuard Home is another self-hosted option, distributed as a standalone binary for Linux, macOS, and Windows. It supports DNS-over-HTTPS and DNS-over-TLS natively and includes built-in parental controls and safe search enforcement. Like Pi-hole, it requires you to provide and maintain the underlying OS.
NextDNS is a cloud-hosted DNS filtering service. You create an account, configure your filtering rules in their web dashboard, and point your devices to NextDNS servers. It offers a generous free tier (300,000 queries/month) and a paid plan for unlimited queries. No self-hosting required.
Cloudflare 1.1.1.1 for Families is a simple, cloud-based DNS service that blocks malware (1.1.1.2) or malware plus adult content (1.1.1.3). There's no dashboard, no account, and no customization — just change your DNS settings and it works. It's the most minimal option on this list.
Self-Hosted vs Cloud-Hosted
The biggest architectural decision is whether to run your DNS filter locally or use a cloud service.
Self-hosted (VeloGuardian DNS, Pi-hole, AdGuard Home) means your DNS queries never leave your local network. The filtering appliance sits between your devices and the internet, resolving queries locally and only forwarding allowed queries to an upstream DNS provider. You maintain full control over your data, your configuration, and your uptime.
Cloud-hosted (NextDNS, Cloudflare) means your DNS queries are sent to the provider's servers for filtering. This is simpler to set up — no local hardware needed — but it means a third party sees every domain your devices resolve. NextDNS is transparent about their privacy policy and offers logging controls, but the queries still traverse the internet. Cloudflare provides no per-user customization beyond their two preset levels.
For privacy-conscious users, self-hosted is the clear winner. For users who want zero maintenance, cloud-hosted is simpler.
Setup & Configuration
Setup complexity varies significantly:
- VeloGuardian DNS — Download the OVA file (~500 MB), import it into your hypervisor (VMware, VirtualBox, or Proxmox), boot the VM, run the console wizard to set a static IP, and point your router's DNS to that IP. Total time: about 10 minutes. No Linux knowledge required.
- Pi-hole — Install a Linux OS on a Raspberry Pi or VM, run the Pi-hole install script, configure networking, and point your router's DNS. You need to be comfortable with the Linux command line. Total time: 30-60 minutes depending on experience.
- AdGuard Home — Download the binary, run it, complete the web-based setup wizard, and point your router's DNS. Faster than Pi-hole but still requires a running Linux/macOS/Windows system. Total time: 15-30 minutes.
- NextDNS — Create an account, configure your filtering profile in the web dashboard, and either change your router's DNS settings or install the NextDNS client on each device. Total time: 5-10 minutes.
- Cloudflare — Change your router's DNS to 1.1.1.2 (malware blocking) or 1.1.1.3 (malware + adult content). No account needed. Total time: 2 minutes.
VeloGuardian DNS strikes a balance: self-hosted privacy with near-cloud simplicity. You get a complete appliance — OS, DNS filter, dashboard, and automatic updates — in a single file.
Filtering Capabilities
All five solutions block domains using blocklists, but the depth of control varies:
- VeloGuardian DNS — Ships with curated blocklists for ads, trackers, malware, and phishing. Supports custom blocklists by URL, per-domain allow/deny rules, category-based filtering (ads, adult content, gambling, social media, etc.), and real-time query log monitoring.
- Pi-hole — Uses community-maintained blocklists (Adlists). Supports custom blocklists, regex filtering, per-domain allow/deny, and group management. No built-in category system — you add or remove blocklists manually to control what's filtered.
- AdGuard Home — Built-in category filters (ads, adult, social media, etc.), custom blocklists, DNS rewrites, per-client settings, and safe search enforcement for major search engines.
- NextDNS — Extensive filtering controls including curated blocklists, category-based blocking, per-device profiles, TLD blocking, and analytics. The most feature-rich option, though all queries are processed in the cloud.
- Cloudflare — Two preset levels: malware-only or malware + adult content. No custom blocklists, no dashboard, no query logging, no per-device configuration.
Privacy & Data Control
DNS queries reveal every website and service your devices connect to — they're among the most sensitive data on your network.
- VeloGuardian DNS — All query data stays on your local appliance. No cloud telemetry, no account, no external data transmission. You own your data completely.
- Pi-hole — Same as VeloGuardian DNS: fully local. Pi-hole's query log lives on your device and is never shared.
- AdGuard Home — Fully local when self-hosted. No data is sent to AdGuard's servers unless you explicitly enable optional features like safe browsing lookups.
- NextDNS — Your queries are processed on NextDNS servers. They publish a clear privacy policy and offer log retention controls (including a no-logging option), but the queries still travel through their infrastructure.
- Cloudflare — Cloudflare states they do not sell DNS data and purge logs within 24 hours. However, your queries are processed on their network, and there's no user-accessible logging or audit trail.
Parental Controls
If you're a parent looking to filter content for your family, here's how each option stacks up:
- VeloGuardian DNS — Category-based blocking for adult content, gambling, social media, and more. Operates at the network level so children can't bypass it by switching browsers or using incognito mode. Manageable from the web dashboard.
- Pi-hole — No built-in parental controls. You can manually add adult content blocklists, but there's no category system or per-device profiles for different family members.
- AdGuard Home — Built-in parental controls with safe search enforcement for Google, YouTube, Bing, and others. Per-client settings allow different rules for children and adults on the same network.
- NextDNS — Strong parental controls with per-device profiles, safe search, YouTube restricted mode, and category blocking. The most granular option, but relies on cloud processing.
- Cloudflare — The 1.1.1.3 address blocks adult content, but there's no customization beyond that single toggle. No logging, so you can't see what was blocked or allowed.
Cost
- VeloGuardian DNS — Free forever. No paid tiers, no feature gates, no account required.
- Pi-hole — Free (open source). Hardware cost for Raspberry Pi (~$35-75) or VM resources.
- AdGuard Home — Free (open source). Same hardware requirements as Pi-hole.
- NextDNS — Free tier: 300,000 queries/month. Pro plan: $19.90/year for unlimited queries.
- Cloudflare — Free. No paid version exists for the Families service.

Which Should You Choose?
The right DNS filter depends on your priorities:
- You want self-hosted privacy with minimal setup: VeloGuardian DNS. Download the OVA, import, boot, and you're done. No Linux knowledge needed, no OS to maintain, and the hardened appliance handles its own updates.
- You're a tinkerer who wants maximum control: Pi-hole or AdGuard Home. Both are excellent self-hosted options if you enjoy managing Linux systems. AdGuard Home is slightly easier to set up and has more built-in features; Pi-hole has a larger community and ecosystem.
- You want powerful filtering without self-hosting: NextDNS. The most feature-rich cloud option with per-device profiles, analytics, and granular blocking rules. The trade-off is that your queries are processed on their servers.
- You just want basic protection with zero effort: Cloudflare 1.1.1.1 for Families. Change one DNS setting and you get malware blocking. No customization, but also no maintenance.
- You're a parent looking for network-wide controls: VeloGuardian DNS or AdGuard Home for self-hosted; NextDNS for cloud-hosted. All three offer category-based blocking that children can't bypass by switching browsers.
- You run a small business: VeloGuardian DNS. The appliance model fits well in business environments with existing virtualization infrastructure, and the zero-cost, zero-account model means no procurement process.
