You can make custom configurations per device, OS or a different label you give them. So you can have your wife see their ads while still blocking your smart TV from calling home.
NextDNS is advertised as Cloudflare + Pi-Hole. And I think this is correct.
Something wrong with the Pi-Hole, I have to sit down (likely at home), and do it -- even to add/edit something. NextDNS is much simpler, I can set up from anywhere and I can even ask my wife to fix herself stuffs.
Must be just personal but these days, I'm not too keen on doing everything myself the way I want. I'm learning to say NO to a lot of things.
What boots up almost instantly? It's supported on quite a few OSes [0], not to mention the underlying hardware. I found AdGuard's (Home) UI to be a bit more polished but it feels like it has feature parity with PiHole 5 otherwise. I tried both but stuck with PiHole since the community around it seemed more developed.
You run it yourself on your own hardware - a PC, Raspberry Pi, Linux server, Docker container - you choose.
It is open source; logging remains with yourself.
It only works inside your own network unless you VPN into your home network when you are remote.
