## What it is
i2pd (I2P Daemon) is a full-featured C++ implementation of an I2P client, providing a universal anonymous network layer with end-to-end encrypted communications that hides participants' real IP addresses. It runs as a lightweight daemon used to build and access anonymous networks for peer-to-peer and client-server applications.

## Use cases
- run an I2P router node to access the anonymous I2P network
- host anonymous websites and chat servers without revealing my IP
- use anonymous peer-to-peer filesharing and cryptocurrency networks
- route my applications' traffic through an end-to-end encrypted overlay network
- self-host a lightweight I2P daemon on a server or router
- develop secure applications using I2P's anonymous networking APIs

## When to choose
- you need a lightweight, fast, C++ I2P implementation with simple dependencies
- you want to run an I2P node headlessly on a server, Docker, or embedded device
- you need anonymous end-to-end encrypted communication without revealing real IPs
- you want developer APIs to build applications on top of the I2P network

## When to avoid
- you need a graphical I2P client - use i2pd-qt, i2pd-android, or gui-i2pd instead
- you only need Tor-style onion routing rather than I2P's garlic routing network
- you want a turnkey anonymizing proxy with no configuration
