Pi-hole is a network-wide ad blocker installed in one place so every device on a network is protected. It runs in Docker or on a supported Linux distribution and is used as a DNS server, with a web interface, built-in DHCP server, group management and allow/deny domain rules. Pairing it with a VPN extends protection on mobile data and public Wi-Fi.
Blacklight is a real-time website privacy inspector from The Markup. A user enters a website address and Blacklight scans it, revealing user-tracking technologies on the site. Tests cover ad trackers, third-party cookies, tracking that evades cookie blockers, session-monitoring scripts, keystroke capturing, and data sent to Facebook, TikTok, Twitter/X and Google Analytics. A scan normally takes between 30 seconds and one minute.
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.
PopUpOFF is a non-commercial, open-source browser extension that removes popups, overlays and cookie notifications. It offers aggressive, moderate and delicate modes, plus an experimental Anti-paid feature. Information is stored locally and the project states it uses no tracking or analytics.
Webbkoll is a service that checks which data-protecting measures a site has taken to help users exercise control over their privacy. It is run by the 5th of July Foundation in Sweden. The tool simulates a normal browser visit with Do Not Track disabled and no add-ons, and http:// is checked even when https:// is entered.
AnonymousRedirect helps block ads, trackers, sponsored segments, popups, or unwanted web content.
Cover Your Tracks is a project of the Electronic Frontier Foundation that tests a browser to show how well it is protected from tracking and fingerprinting. It shows how trackers view the browser and gives an overview of the browser's most unique and identifying characteristics. Only anonymous data is collected through the site.
