AdGuardDNS VS dnsproxy

I've tried hosted Pi-Hole and AdGuard Home. They are good as long as I'm around to fix stuffs. Then I tested something which can be global (home) and also for individual devices -- Control-D, NextDNS, and Adguard DNS. All of them works pretty well. If I really have to choose, then it would be in the order of NextDNS > Control-D > AdGuard DNS. Affiliated with none, and have decided to subscribe to all three to further test them for this year.

I used Pi-Hole, then went to NextDNS, then to AdGuard DNS, tinkered with AdGuard Home, and currently testing Control-D. They are all actually pretty good, similar features, and it has become just a matter of personal choice.

In all fairness, when I have some time and can invest in decent hardwares, I might go back to AdGuard Home with one of the paid services as backup for travel, and when for the other family members.

Pi-Hole works really well but once-a-while, when I'm traveling, it will decide to act up and it's a whole IT support with the family over phone for minutes if not hours. I'm not smart enough to setup a secure enough tunnel and the like, and haven't read up enough on the topic. This follows similar pattern with AdGuard Home.

NextDNS, AdGuard DNS, Control-D are easy and just works, especially with the devices that the family uses. I think I bought one of those AdGuard Lifetime license, so I use that to block client-side rendered ads in conjunction with either AdGuard DNS or NextDNS or Control-D. Right now, Control-D is doing pretty good with my test-drive.

In the case of AdGuard DNS being open source does not change the fact that it is a centralized service and using such a service is a matter of trust.

Then just unlock it. I am not sure which Adguard method you use, if you use a personal one which I recommend then you can just whitelist the domain that is used. If you use the general DNS then use https://adguard-dns.io/ to customize it. Trust me you will like it.

Google is your friend my dude.. https://ourpact.com/ and https://adguard-dns.io/

A feature request has been made for ECH support for AdGuard DNS, but there has been no further information added. You can follow the issue tracker here.

On my Mac Adguard DNS (i.e. adguard-dns.io) does not work without the Adguard app.

There's no difference between the free and freemium in regards to customizability while using VPN since both offer DoT endpoints. On Android, with the standard WireGuard & OpenVPN app you can use any DoT provider you want since the Android Private DNS setting takes precedence over the DNS settings in the VPN app. In Windows you can run https://github.com/AdguardTeam/dnsproxy locally, that way the VPN won't intercept and modify the local DNS traffic (the DNS upstream still goes through the VPN, but if you use DoT/DoH/DoQ then it continues to the DNS server you prefer).

Which OS is this? In Android the Private DNS (DoT) setting is respected by some clients like the standard WireGuard & OpenVPN, so you can just load any provider's config and enter your personal DoT address. In iOS Passepartout can accept WG/OpenVPN config and apply custom DoH, as for desktop OS you can just run https://github.com/AdguardTeam/dnsproxy forwarding to your DoH/DoQ address and set the VPN interface to use localhost as DNS.

If it's on a desktop/laptop, you can run https://github.com/AdguardTeam/dnsproxy to forward into your NextDNS DoH/DoT/DoQ, and set your VPN network adapter to use 127.0.0.1, 127.0.0.2, ::1 and ::2 for DNS (the secondary entry either loopback or fail entirely, all it matters is your OS shouldn't try other address), that way since local traffic isn't routed by the VPN, you still get NextDNS (the actual DoH/DoT/DoQ traffic is still going through the VPN).

Why not set AdGuard Home (assuming it's indeed installed at your home) to use DoT/DoH/DoQ upstream (so your ISP can't redirect it) and have the rewrites in AGH too? If your AGH instance isn't at home, assuming you're using Windows 11 set your AGH to listen on DoH and set Windows to use DoH to your AGH. Otherwise use dnsproxy in Windows to forward it to your AGH through DoT/DoH/DoQ.

I'm not sure what is your plan here, do you need the Surfshark feature specifically, or do you just want to hide your traffic from your ISP? If you need Surfshark (perhaps for streaming geoblocked content or torrenting), then integrating it with AGH hosted on the cloud for device-wide traffic is going to be complicated. The Surfshark client doesn't support custom DoH/DoT address nor IPv6 (opening public IPv4 Do53 is a big no-no, you'll get swamped for DNS amplification attack), so you'll need an app running on your device to redirect DNS traffic like https://github.com/AdguardTeam/dnsproxy to your cloud AGH. You'd need to setup DoH with a custom path through Nginx otherwise people would scan your server and use it, plus if Google's crawler sees the AGH login page it will mark it as deceptive, and your entire domain is blacklisted by the Safe Browsing API that's used on multiple products (Chrome, Firefox, AdGuard, NextDNS, etc). With all that hassle might as well just run AGH locally on your device anyway (local traffic isn't handled by VPNs)

Assuming you have a custom upstream, it's by design

Since nextdns-cli isn't likely to support DoQ anytime soon, your best bet is dnsproxy and ctrld.
