> Auto-detect OS and suggest specific setup instructions right on the landing page?
It should already pre-select your OS tab on my.nextdns.io on the Setup page? If that's not the case, then it's probably a bug.
Weird, we will have a look.
> simplednscrypt has been handy for me to DoT/DoH/DNSCrypt with AdGuard DNS on PC. You could include instructions in the Windows section for that? https://dnscrypt.info/implementations/
You can use your custom sdns:// endpoint listed on the Setup page, we assumed users using dnscrypt clients would know what this means. Good point, we will add setup instructions for it.
> Provide a generic DNS endpoint like AdGuard does?
We already have them, we decided to not show them on the website as it may confuse users. We may add them back.
> What's the backend that fronts DoH, DoT, and DNSCrypt queries? Is it simply relayed to Cloudflare underneath the covers? How do you do that?
It's a custom-made backend, and we recurse using unbound (we don't forward to cloudflare or anything like that).
We will definitely improve that, we had to make some calls on priorities for the launch.
(Since the most recent batch of CPU vulnerabilities, I have decided to use uMatrix to block anything but CSS by default.)
