CleanBrowsing is a free public DNS resolver[1] with content filtering, founded by Daniel B. Cid. It supports DNS over TLS[2] over port 853 and DNS over HTTPS[3] over port 443 in addition to the standard DNS over port 53. CleanBrowsing filters can be used by parents to protect their kids from adult and inappropriate content online.[4]
