On the plus side it is open source and the free tier with unlimited queries. The free tier of NextDNS is limited to (I think) 300,000 queries. If you want a free and open source alternative this is it. At the time of writing, their website does state that paid plans are on their way.

Cloud DNS blocks ads, trackers, and malicious domains for all devices, provides real-time request stats, customizable filtering, parental controls, and a web dashboard. Compatible with routers, enables safer browsing, and ensures a privacy-focused internet experience.
