What are the best I2P alternatives?

I2P is described as 'The I2P network provides strong privacy protections for communication over the Internet. Many activities that would risk your privacy on the public Internet can be conducted anonymously inside I2P' and is a very popular anonymizing network in the security & privacy category. There are more than 25 alternatives to I2P for a variety of platforms, including Windows, Linux, Mac, BSD and Online / Web-based. The best alternative is Tor, which is both free and Open Source. Other great apps like I2P are Matrix.org, Freenet, ZeroNet and IPFS.

I2P alternatives are mainly Anonymizing Networks but may also be VPN Services or Social Networks. Filter by these if you want a narrower list of alternatives or looking for a specific functionality of I2P.
