i2p/i2p.i2p
I2P is an anonymizing network, offering a simple layer that identity-sensitive applications can use to securely communicate. All data is wrapped with several layers of encryption, and the network is both distributed and dynamic, with no trusted parties. observed · 2026-08-28

I2P (Invisible Internet Project) is the reference Java implementation of a decentralized, anonymizing peer-to-peer overlay network that routes traffic through layered-encryption tunnels across volunteer-operated routers. It provides a self-contained censorship-resistant network layer with APIs (SAM, I2PTunnel, SOCKS proxy, streaming) that identity-sensitive applications can use for anonymous communication.
Use cases
- browse eepsites anonymously over the i2p network
- run an anonymous torrent client over i2p
- host a hidden website that hides my server's IP
- send anonymous email with i2p mail
- route applications through an anonymous socks proxy
- communicate anonymously in censored or restrictive countries
- embed anonymous networking in my java application via the i2p api
When to choose
- you need anonymous, end-to-end encrypted communication with no trusted central parties
- you want to host or access hidden services (.i2p eepsites) rather than proxy to the clearnet
- you need a censorship-resistant network with hidden-mode operation in restrictive jurisdictions
- you want a self-contained anonymous network with built-in applications like torrent, mail, and IRC
When to avoid
- you mainly need to browse the regular web anonymously through exit nodes - Tor is a better fit
- you need a lightweight proxy without running a full router that participates in relaying traffic
- you require a non-Java runtime and cannot run a JVM (consider i2pd, the C++ implementation)
- you need low-latency communication where tunnel routing overhead is unacceptable
