FilterDNS vs NextDNS

FilterDNS is a self-hosted DNS filtering service for blocking ads, trackers, and malware. It supports DNS over HTTPS on port 443, DNS over TLS on port 853, and legacy DNS on port 53. Users can create separate profiles for different devices or use cases, with custom domain allow and deny rules and preset rule sets such as gaming and social media. Preconfigured blocklists include Hagezi, StevenBlack, and OISD. Query logs and statistics let users review DNS requests; logging is enabled by default in the documented configuration. Filtering can be paused for 5, 15, 30, or 60 minutes, and maintenance mode allows DNS only for approved domains. The project documents API endpoints for profiles, logs, statistics, rules, presets, devices, and administration. Its Docker Compose quick start uses PostgreSQL and a SvelteKit web UI available locally at http://localhost:8080. DoH and DoT require a wildcard TLS certificate for the service domain. FilterDNS is MIT-licensed and free to self-host.

NextDNS filters internet traffic to block security threats, ads, and trackers, and offers controls for supervising children's access across devices and networks. Its listed threat protections include malware, phishing, cryptojacking, DNS rebinding, lookalike domains, typosquatting, domain generation algorithms, and newly registered domains. Parental controls include category blocking, SafeSearch, YouTube Restricted Mode, and blocks for specific sites, apps, and games, plus scheduled Recreation Time. DNS-over-HTTPS and DNS-over-TLS provide encrypted DNS connections. Users can disable logging or choose retention from one hour to two years and select storage in the United States, European Union, United Kingdom, or Switzerland. The free plan costs nothing and includes 300,000 queries per month; after the limit, it continues answering as a non-blocking DNS service. Pro costs £1.79 a month. Business and Education each cost £17.90 a month, for every 50 employees or 250 students respectively. Free and Pro list community support; Business and Education list email support.
