Privoxy vs Roadblock

Privoxy is free, non-caching web proxy software for privacy controls, access rules, and changes to HTTP headers and web pages. It can modify page text, remove banners and web bugs, filter HTML annoyances, and inspect HTTPS requests and responses. A browser-based configuration and control utility includes rule tracing and remote toggling, and Privoxy can be chained with other proxies. It can serve multiple clients across a network or as a LAN gateway. The software runs on Windows, GNU/Linux, Mac OS X, Haiku, BSD variants, Solaris, and other Unix systems. It is licensed under the GNU GPL version 2 or later, with a free plan listed at free. A basic configuration is included with a new installation, but many advanced features need to be enabled. Privoxy handles HTTP and HTTPS proxying; it does not handle FTP, SMTP, instant messaging, IRC, or ICQ. It is not designed as a malware-removal tool, and the default setup does not filter malware. The project says it lacks trusted build infrastructure; individual project members or external contributors build and upload binary packages.

Roadblock is a freemium Safari content blocker for iPhone and Mac that controls how web content loads. It blocks advertisements, including pop-ups and video ads, plus scripts that track activity on webpages and across the web. It can remove chat widgets, cookie-consent, newsletter, and notification banners, subscription overlays, and AI widgets. Custom rules can block or allow sites and content, hide elements, strip cookies, and force HTTPS. Separate profiles support Wi-Fi, cellular browsing, or family use and can be shared with friends. The iPhone page lists 322K+ built-in rules, with additional ad-blocking rules for non-English sites in 37 languages. Optional iCloud sync shares profiles and settings between Mac, iPhone, and iPad and is off by default. Roadblock says it does not collect or store personal information, and extensions do not access browsing activity or report blocked content. It supports iOS 15+ and macOS Big Sur 11+. Premium plans start at $0.99 a month or $5.99 a year.
