Retroshare establish encrypted connections between you and your friends to create a network of computers, and provides various distributed services on top of it: forums, channels, chat, mail...
Retroshare is fully decentralized, and designed to provide maximum security and anonymity to its users beyond direct friends. Retroshare is entirely free and open-source software. It is available on Android, Linux, MacOS and Windows. There are no hidden costs, no ads and no terms of service.
* Chat Send text and images. Discuss with various people in decentralized chat rooms (like IRC). Express your emotions with the rich smiley set. Use distant chat to securely chat with friends-of-friends.
* Mail Send encrypted messages to other members of the network. Retroshare securely stores messages on friends nodes to deliver messages while youre offline.
* File sharing Share files with your friends or with the whole network. Use the search to find files. Retroshare uses swarming similar to BitTorrent, to accelerate transfers. This makes it possible to share large files. Your privacy and anonymity is guaranteed beyond direct friends with anonymous tunnels.
* Forums You can read and write forum posts offline. This is perfect while youre on the go. When you have an Internet connection, Retroshare will automatically sync forums with your friends. Decentralized forums are censorship resistant by design.
* Links Share your favorite links. See which links others like. Vote and discuss them using the built-in commenting system.
* Channels Channels allow you to publish your files. You may subscribe to channels and automatically download the latest files; comment on files and spread them to your friends.
* Protect your IP with Tor/I2P Retroshare can optionally be used over the Tor and I2P networks. Doing so, even friend nodes cannot see your IP, which allows to safely and anonymously connect to unknown people.
While it is always possible to configure a normal Retroshare node to also use Tor, we provide specific builds that embed and manage Tor automatically, to ease things up. This is an excellent way to safely try the software while connecting to untrusted users.
