NextDNS blocks ads, trackers, and malicious domains at the DNS level so its filtering applies to every device you route through it rather than a single browser. You get a configurable dashboard with blocklists, parental controls, and logs, plus built-in encrypted DNS (DoH/DoT). The hosted service is closed-source, though its client apps and CLI are open and it is run by a US-registered company so it sees your DNS queries by design. The free tier covers 300,000 queries a month, enough for casual use before a paid plan is needed.
