DNS & Privacy

Pi-hole, AdGuard, NextDNS, Quad9 — DNS-level privacy.

DNS & Privacy is one of the categories most polluted by affiliate-driven content. Almost every review you'll find is paid to recommend NordVPN. Our reviews are written by network engineers — and we recommend the tools we actually run.

What you'll find here:

• Head-to-head comparisons — like Pi-hole vs AdGuard — where we test products side by side on the same workloads, with the same datasets, under the same constraints.
• Tutorials — when a tool has a high learning curve, we publish step-by-step setup guides written by people who've configured it for real production use, not toy projects.
• Listicles — ranked by use case, not affiliate payout. We disclose every affiliate relationship in our disclosure.

Editorial standards for DNS & Privacy

Every piece in this category has been reviewed by an editor with hands-on experience in the relevant tool or workflow. We don't publish AI-only content. We don't accept gifted hardware. We don't publish reviews of products we haven't used.

If we recommend a paid tool, the affiliate link is clearly marked with data-aff, and the recommendation is independent of payout. We've actively rejected several lucrative partnerships because the products didn't survive our internal testing.

How we test DNS & Privacy tools

Our test methodology is published per-review at the bottom of each comparison piece. In general:

1. Real workloads — we don't run synthetic benchmarks. Each tool is tested on the workload an actual operator would run.
2. Multi-month evaluation — we never publish a review based on less than 30 days of real use. Many of our reviews represent 6-12 months of production usage.
3. Editor-reviewed — every comparison goes through a senior editor in the category before publication.
4. Reader-corrected — when readers point out errors or out-of-date information, we update with a visible changelog.
