That's something people should run themselves. I run Adguard Home on my router. Unlike the main Adguard product, Adguard Home is fully FOSS. It's been rock-solid for me, and improves on pi-hole in various ways - like full IPv6 support.

It's probably the software I trust the most on my network to 'just work', and with the local caching I can use slower upstream dns providers and still have sub 1ms average latency (no performance worries by excluding google and cloudflare). I don't use it for dhcp, but it is a good fit that it's available as well. Couldn't be happier.

I use Mullvad's adblocking DNS server on my phone which is not always behind my home router.
