Best NextDNS Alternatives for Custom DNS Filtering

If you want customizable DNS filtering without NextDNS’s usage limits or account requirements, the top pick is AdGuard Home. It’s free, self-hosted, and gives you per-device blocking rules, custom lists, and full control over your logs — all without sending data to a third party.

What to Look For

When comparing DNS filtering services, focus on these criteria:

• Customization depth – Can you add your own blocklists, allowlists, and per-device rules? A simple on/off filter is not enough for advanced users.
• Privacy and logging – Does the service keep logs? Can you disable them? Self-hosted options give you the most control.
• Performance and uptime – Look for anycast networks, low latency, and a solid SLA. A slow DNS server makes everything feel sluggish.
• Ease of setup – Some services require flashing a router or running a Docker container. Others work with a simple app or device configuration.
• Cost – Free tiers often have limits (e.g., 300,000 queries/month on NextDNS). Paid plans remove those caps but add monthly fees.
• Platform support – Check whether the service offers apps for Windows, macOS, iOS, Android, and routers, or if you must configure manually.

AdGuard Home

AdGuard Home is a network-wide DNS server that you run yourself. It blocks ads, trackers, and malicious domains using filter lists you choose. You can create custom rules, set up per-client settings, and view query logs that you fully control.

Strengths: Completely free, no query limits, and no third-party logging. You can install it on a Raspberry Pi, a NAS, or a cloud VPS. The web interface is clean and responsive, and it supports DNS-over-HTTPS and DNS-over-TLS.

Trade-offs: Requires maintenance — you must update the software and manage the server yourself. There’s no official mobile app; you configure your devices to point to your server’s IP.

Who it suits: Tech-savvy users who want full control and privacy, and who don’t mind a bit of setup.

Pi-hole

Pi-hole is the classic network-wide ad blocker. It runs on a Raspberry Pi or any Linux machine and works by blocking DNS queries to known ad and tracker domains. It has a simple dashboard showing top blocked domains and clients.

Strengths: Proven, widely used, and free. It has a huge community and many blocklists. It integrates with Unbound for recursive DNS, giving you complete privacy.

Trade-offs: Primarily designed for local network use — remote access requires extra setup (VPN or port forwarding). It lacks some of AdGuard Home’s features like per-client DNS-over-HTTPS and a more modern UI.

Who it suits: Home users who want a simple, reliable network-wide blocker and already have a Raspberry Pi or Linux box.

Control D

Control D is a modern, cloud-based DNS filtering service with a generous free tier (1 million queries/month). It offers customizable rules for different device types, and you can create your own filter lists or use their pre-built categories.

Strengths: Very easy to set up — just change your DNS server or install an app. It has per-device profiles, so you can have different rules for your phone and laptop. The free tier is quite generous compared to NextDNS’s 300,000.

Trade-offs: The free tier logs some data (you can opt out). Advanced features like custom rules and analytics require a paid plan. The interface can be slightly overwhelming for beginners.

Who it suits: Users who want a hosted service with a generous free tier and don’t want to manage a server.

OpenDNS (Cisco Umbrella)

OpenDNS is one of the oldest DNS filtering services. The free home version lets you block categories like adult content, social media, and malware. You can set up per-network or per-device policies.

Strengths: Reliable, fast, and backed by Cisco. The free tier is enough for basic content filtering and phishing protection. Setup is straightforward — just point your router to their DNS servers.

Trade-offs: Very limited customization compared to NextDNS or AdGuard Home. You cannot add custom blocklists, and the free version shows a “blocked” page that you can’t fully customize. Logs are kept for a limited time (privacy trade-off).

Who it suits: Families or small businesses that want simple content filtering without any technical fuss.

Blahdns

Blahdns is a privacy-focused public DNS resolver that blocks ads, trackers, and malware. It’s hosted in a few locations (Germany, Japan, Finland) and supports DNS-over-HTTPS, DNS-over-TLS, and DNSCrypt.

Strengths: Free, no logging, and no account needed. You just configure your device to use their DNS servers. It’s a good option if you want a simple, private DNS that blocks major annoyances.

Trade-offs: No customization — you can’t add your own blocklists or rules. Server locations are limited, so latency might be higher outside those regions. The service is run by volunteers, so uptime is not guaranteed.

Who it suits: Privacy-conscious users who want a no-fuss, free DNS blocker without any account or setup complexity.

CleanBrowsing

CleanBrowsing offers family-friendly DNS filtering with several tiers. The free tier includes adult content blocking and malware protection. Paid plans add more categories, custom rules, and analytics.

Strengths: Very effective at blocking adult content and phishing. It has a fast anycast network. The free tier is sufficient for basic family protection.

Trade-offs: The free tier has limited customization — you can’t add custom blocklists. To get per-device policies or detailed logs, you need a paid plan. Some users may find the “safe search” enforcement too aggressive.

Who it suits: Families who want a reliable, easy-to-set-up content filter for kids.

How to Choose

Start by deciding whether you want a self-hosted or hosted service. Self-hosted (AdGuard Home, Pi-hole) gives you total control and privacy but requires hardware and maintenance. Hosted services (Control D, OpenDNS, CleanBrowsing) are easier but may log data or charge for advanced features.

Next, consider your budget. If you want to spend nothing, AdGuard Home or Pi-hole are your best bets — they’re free forever. Control D’s free tier is also generous, but you might eventually hit the query limit if you have many devices.

Think about use case:

• For a home network with multiple devices, AdGuard Home or Pi-hole are ideal.
• For a family with kids, CleanBrowsing or OpenDNS offer simple content filtering.
• For a single device or a traveler, Control D or Blahdns are easy to set up on your phone or laptop.

Finally, consider privacy vs. convenience. Self-hosted options keep all data local, but you must manage them. Hosted services are convenient but may keep logs or require trust in the provider.

Frequently Asked Questions

Can I use these alternatives alongside NextDNS?

Yes, you can run multiple DNS filters, but only one can be active per device. You might use NextDNS on your phone and AdGuard Home on your home network, for example.

Do I need a Raspberry Pi to run AdGuard Home?

No, you can run it on any Linux server, a NAS, or even a Windows PC. A Raspberry Pi is just a low-power, always-on option.

Will these services slow down my internet?

Most are fast, but a self-hosted server on weak hardware might add a few milliseconds. Cloud services like Control D or OpenDNS are typically very fast due to anycast networks.

Can I block specific websites with these tools?

Yes, most allow custom rules. AdGuard Home and Pi-hole let you add wildcard domains. Control D and CleanBrowsing (paid) also support custom rules.

Do these services work on mobile data?

Yes, if you configure your phone’s DNS settings or install their app. Control D and NextDNS have mobile apps, while AdGuard Home requires you to set a private DNS (Android) or profile (iOS).

Which one is the most private?

AdGuard Home and Pi-hole are the most private because you control the server and logs. Blahdns also claims no logging, but you’re trusting a third party.

Bottom Line

For most users, AdGuard Home is the best NextDNS alternative because it offers deep customization, complete privacy, and no limits — all for free. If you prefer a hosted service with zero maintenance, Control D is a strong contender with a generous free tier. For simple family filtering, CleanBrowsing or OpenDNS are reliable choices. Choose based on your technical comfort and privacy needs.
