VeloGuardian DNS vs Pi-hole vs NextDNS: Which DNS Filter is Best?

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 free tier with a query limit 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.

Setup & Configuration

Setup complexity varies significantly across these five solutions.

VeloGuardian DNS is the fastest self-hosted option. 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. About 10 minutes total, no Linux knowledge required.

Pi-hole requires more hands-on work: 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, and setup typically takes 30-60 minutes depending on experience. AdGuard Home is faster than Pi-hole — download the binary, run it, complete the web-based setup wizard — but still requires a running Linux, macOS, or Windows system. Expect 15-30 minutes.

On the cloud side, NextDNS takes 5-10 minutes: create an account, configure your filtering profile, and either change your router's DNS or install the NextDNS client on each device. Cloudflare is the simplest of all — just change your router's DNS to 1.1.1.2 (malware blocking) or 1.1.1.3 (malware + adult content). No account needed, done in about 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

With self-hosted solutions like VeloGuardian DNS, Pi-hole, and AdGuard Home, all query data stays on your local appliance. No cloud telemetry, no account, no external data transmission — you own your data completely. AdGuard Home is fully local unless you explicitly enable optional features like safe browsing lookups.

Cloud-hosted services handle this differently. NextDNS processes your queries on their 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 states they do not sell DNS data and purge logs within 24 hours, but your queries are processed on their network with no user-accessible logging or audit trail.

Parental Controls

If you are a parent looking to filter content for your family, the differences between these solutions are significant.

VeloGuardian DNS offers category-based blocking for adult content, gambling, social media, and more. Because it operates at the network level, children cannot bypass it by switching browsers or using incognito mode — and everything is manageable from the web dashboard. AdGuard Home also provides strong parental controls with safe search enforcement for Google, YouTube, and Bing, plus per-client settings that allow different rules for children and adults on the same network.

NextDNS offers the most granular parental controls — per-device profiles, safe search, YouTube restricted mode, and category blocking — though it relies on cloud processing. Pi-hole has no built-in parental controls; you can manually add adult content blocklists, but there is no category system or per-device profiles. Cloudflare blocks adult content at the 1.1.1.3 address, but there is no customization beyond that single toggle and no logging to see what was blocked.

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 — Freemium. Limited free tier with a paid plan 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.

If you want self-hosted privacy with minimal setup, VeloGuardian DNS is the best fit. Download the OVA, import, boot, and you are done. No Linux knowledge needed, no OS to maintain, and the hardened appliance handles its own updates. The same recommendation applies if you run a small business — the appliance model fits well in environments with existing virtualization infrastructure, and the zero-cost, zero-account model means no procurement process.

If you are a tinkerer who wants maximum control, Pi-hole or AdGuard Home are both excellent self-hosted options. AdGuard Home is slightly easier to set up and has more built-in features, while Pi-hole has a larger community and ecosystem. Both require you to manage the underlying Linux system.

If you want powerful filtering without self-hosting, NextDNS is the most feature-rich cloud option — per-device profiles, analytics, and granular blocking rules — with the trade-off that your queries are processed on their servers. For basic protection with zero effort, Cloudflare 1.1.1.1 for Families lets you change one DNS setting and get malware blocking immediately, though with no customization.
