Control D vs. CatBlock

Control D is a versatile DNS filtering and traffic redirection service that utilizes advanced Secure DNS protocols such as DNS-over-HTTPS, DNS-over-TLS, and DNS-over-QUIC, while also accommodating traditional DNS. With Control D, users can effectively eliminate harmful threats, restrict various types of undesirable content across the network—including advertisements, trackers, IoT data, adult material, social media, and more—while also redirecting traffic through transparent proxies and monitoring network activities and usage patterns at a client-specific level. Consider it your own personalized Authoritative DNS resolver for the entire Internet, providing you with detailed control over which domains are allowed to be resolved, redirected, or blocked. This capability not only enhances security but also empowers users to tailor their online experience according to their preferences.

Meet CatBlock, a groundbreaking ad-blocking extension that swaps out pesky advertisements for adorable cat images. This extension operates as a standalone ad blocker and is designed to work seamlessly with major browsers such as Google Chrome, Opera, and Mozilla Firefox on desktop systems. By utilizing the open-source foundation of AdBlock, we have creatively turned the ads you usually overlook into captivating pictures of cats! Our dedicated team, made up of experienced contributors from the original AdBlock initiative, applied their knowledge to develop this distinctive version. Like its predecessor, CatBlock is entirely open-source and complies with the GNU GPLv3 license, allowing users to dive into our code on GitHub.
