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, Android and iPhone apps. The best I2P alternative is Tor, which is both free and Open Source. Other great apps like I2P are Matrix, Hyphanet, Snowflake Tor and IPFS.
Tor is free software and an open network that helps you defend against traffic analysis, a form of network surveillance that threatens personal freedom and privacy, confidential business activities and relationships, and state security.
Matrix defines a set of open APIs for decentralised communication, suitable for securely publishing, persisting and subscribing to data over a global open federation of servers with no single point of control.
Hyphanet (former Freenet) is free software which lets you anonymously share files, browse and publish "freesites".
Snowflake is a system to defeat internet censorship. People who are censored can use Snowflake to access the internet. Their connection goes through Snowflake proxies, which are run by volunteers.

IPFS is a global, versioned, peer-to-peer filesystem. It combines ideas from Git, BitTorrent, Kademlia, SFS, and the web. It is like a single bittorrent swarm, exchanging git objects. IPFS provides an interface as simple as the HTTP web, but with permanence built in.
ZeroNet uses cryptography (Bitcoin library) and BitTorrent DHT (centralized trackers) to build a distributed censorship-resistant network.
GNUnet is a framework for secure peer-to-peer networking that does not use any centralized or otherwise trusted services. A first service implemented on top of the networking layer allows anonymous censorship-resistant file-sharing.
Protects internet traffic through a decentralized mixnet, hides metadata and communication patterns, enables anonymous transactions using re-randomizable credentials, and provides zero-knowledge proof access for privacy-focused messaging, blockchain, or application needs.
Lokinet is a decentralised onion router that uses Oxen service nodes as relays, giving Lokinet the same market-based Sybil attack resistance as the Oxen blockchain. Lokinet supports web browsing, onion-routed real-time voice communications, and other applications.
I2P (Invisible Internet Protocol) is a universal anonymous network layer. All communications over I2P are anonymous and end-to-end encrypted, participants don't reveal their real IP addresses.
A proof-of-concept scalable IPv6 meshnet, featuring end-to-end encryption, a unique spanning tree routing algorithm and aiming to implement novel backpressure routing metrics.

Same care. Almost the same high encryption standard. Both private enough to use without worry about mitm or snoops.
