LibRedirect is described as 'A web extension that redirects YouTube, Twitter, Instagram... requests to alternative privacy friendly frontends and backends' and is a popular Privacy Tool in the web browsers category. There are more than 10 alternatives to LibRedirect for a variety of platforms, including Mozilla Firefox, Google Chrome, Web-based, Android and Mac apps. The best LibRedirect alternative is Privacy Redirect, which is both free and Open Source. Other great apps like LibRedirect are URLCheck, Redirector, Predirect and UntrackMe.
LibRedirect was forked from Privacy Redirect in the first place, to have an easily updated list of instances and include more frontends to the project. It is indeed a good alternative, but with less features and outdated since December 2021.
