NextDNS is a DNS-based firewall that protects against security threats, blocks ads and trackers, and provides parental controls across devices and networks. It offers encrypted DNS protocols, multiple threat intelligence feeds, and configurable logging with data residency options. Plans include a free tier limited to 300,000 queries per month and paid tiers for personal, business, and education use.
TBlock is a systemwide content blocker written in Python and licensed under GPLv3. It uses the hosts file to block ads and trackers across browsers and other applications, and is available as command-line tools and a graphical application. It supports several filter list formats and automatic list updates.
Portmaster is a free and open-source application firewall from Safing that monitors network connections on a computer. It blocks trackers and malware hosts system-wide and routes DNS queries over DNS-over-TLS by default. Users can set global and per-application rules, including cutting off applications from the internet or restricting connections to certain countries. Downloads are offered for Windows, Debian/Ubuntu and Fedora.
A free public DNS resolver focused on privacy and security. It blocks domains associated with ads, tracking, malware, scams and phishing, and offers DNS-over-HTTPS, DNS-over-TLS, DNS-over-QUIC and DNSCrypt. The operator states that IP addresses and DNS queries are not logged and that data is not shared with third parties.
Database is a privacy tool for blocking ads, trackers, popups, proxies, or unwanted web behavior.
A knowledge base page that suggests a list of trusted DNS providers, including public anycast resolvers such as AdGuard DNS, 360 Secure DNS and Ali DNS. It states that AdGuard Ad Blocker or AdGuard VPN must first be installed on a device before a provider link is used. AdGuard DNS servers are listed for blocking ads, tracking and phishing, for family protection, and for unfiltered connections.
