Actually, very good. But they should add adblocking too.

Interesting suggestion. A privacy-focused DNS service from Proton could definitely be valuable for users who want more control over their data and browsing security. With growing concerns around tracking and data collection, alternatives that prioritize privacy would likely attract many users. By the way, while exploring different platforms online recently, I also came across https://bitkingzcasinowin.com/ which looks interesting for people who enjoy online gaming. Thanks for sharing this idea.

What's wrong with Quad9 DNS? It's European and private.

Dear Proton Team,
There is one critical gap in the privacy ecosystem: a standalone, customizable, privacy-first public DNS service. Google (8.8.8.8) and Cloudflare (1.1.1.1) dominate — both companies whose core business depends on data. NextDNS and AdGuard DNS offer better privacy, but neither is backed by Swiss law or the trust Proton has built. Proton DNS could change that.
What it must be:
A full platform — not just a resolver. Custom blocklists, per-device profiles, analytics, DoH/DoT/DoQ support, and zero logs. NextDNS has customization. AdGuard has filters. Proton DNS must have both — wrapped in Swiss-grade privacy that neither competitor can match.
The South Caucasus — a strategic opportunity.
Azerbaijan, Georgia, and Armenia together have nearly 15 million internet users. Not a single privacy-focused DNS provider has infrastructure here. This region sits at the intersection of Russia, Iran, Turkey, and the West — privacy tools are not a luxury here, they are a necessity. A single server in Baku, Tbilisi, or Yerevan would serve all three countries and position Proton as the privacy leader in a region no competitor has claimed yet.
The infrastructure window is open right now. Whoever arrives first, wins.

A SERVICE LIKE Nextdns, BUT WITH THE REAL PRIVACY WITH PROTON

A Proton DNS application would be a genuinely strong alternative to many of the currently inadequate or closed-source DNS services on the market. Providing features such as blocklists, allowlists, and support for other open-source filtering lists within the application, along with extensive customization options, would make it a valuable complement to Proton VPN for users who want to use both VPN and DNS together.

DNS leaks are bad tho

Proton DNS, please ;)

Just use Quad9.

My home router does not support installing the full Proton 'upgrade', but I would love to be able to set it to a Proton-managed DNS address for the added security and privacy. I have the VPN on all my computers, tablets, and phones, but other connected devices within my house don't have any protection. My main concern are the spying devices , AKA smart televisions, that I have no control over.

would also absolutely need ProtonVPN integraton

Just make sure users have the ability to customize the blocks as with NextDNS

Something like this would be an incredible addition to the Proton ecosystem. Not only could it integrate nicely with the VPN offering, but something that replaces NextDNS with a good privacy backing would be a game changer.

What would make a Proton DNS better than quad9 (9.9.9.9)? I'd rather they focus their efforts creating private tools for which there aren't other good options.

Proton DNS similar to NextDNS or Adguard DNS would be very nice. With server locations all around the world (low pings!) and filter lists that can be customized to one's likings.
This would fit perfectly in Proton's security and privacy portfolio!

you could use MullvadDNS in the meantime

You have Quad9, at 9.9.9.9

I would like to have a customised DNS filter like NextDNS

To me, the existing combination of ProtonVPN and Quad9 (when not using a VPN) make this a solution looking for a problem. Or to put it another way, if there were a ProtonDNS, how would it be much different than Quad9?
