The Tor software protects you by bouncing your communications around a distributed network of relays run by volunteers all around the world: it prevents somebody watching your Internet connection from learning what sites you visit, it prevents the sites you visit from learning your physical location, and it lets you access sites which are blocked.

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.

Freenet is free software which lets you anonymously share files, browse and publish "freesites" (web sites accessible only through Freenet) and chat on forums, without fear of censorship. Freenet is decentralised to make it less vulnerable to attack, and if used in "darknet" mode, where users only connect to their friends, is very difficult to detect.

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. Anonymity is provided by making messages originating from a peer indistinguishable from messages that the peer is routing. All peers act as routers and use link-encrypted connections with stable bandwidth utilization to communicate with each other. GNUnet uses a simple, excess-based economic model to allocate resources. Peers in GNUnet monitor each others behavior with respect to resource usage; peers that contribute to the network are rewarded with better service. »

Lantern allows you to give or get access to the internet through other users around the world connected by a trust-based peer-to-peer network.

OnionCat creates a transparent IPv6 layer on top of TOR's hidden services. It allows users to anonymously access Internet services. It transmits any kind of IPv6-based data transparently through the TOR network on a location hidden basis. You can think of it as a point-to-multipoint VPN between hidden services. OnionCat is a stand-alone application which runs in userland and is a connector between TOR and the local OS. Any protocol which is based on IPv6 can be transmitted. Of course, UDP6 and TCP6 (and probably ICMP6) are the most important ones but all other protocols can also be forwarded through it. OnionCat's main purpose is to allow any user an easy use of hidden services and to allow hidden service providers to provide any type of service. »

Mesh routing protocol designed to handle a massive amount of nodes with very low resource consumption. Thanks to this feature it can be easily used to build a worldwide distributed, anonymous and uncontrolled network, separated from the Internet, without the support of any servers, ISPs or authority controls.

Bitmask is an open source application to provide easy and secure encrypted communication. You can choose among several different service providers or start your own. Currently, Bitmask supports encrypted internet (VPN) and encrypted email.

ThePirateBrowser is a bundle package of the Tor client ( Vidalia ), Mozilla Firefox Portable browser (with FoxyProxy addon) and some custom configs that allows you to circumvent censorship that certain countries such as Iran, North Korea, United Kingdom, Belgium, Finland, Denmark, Italy and Ireland impose onto their citizens.

What is CacheBrowser?

LibreMesh is a set of modules extending the OpenWrt router distribution to create self-configuring wireless and wired mesh networks.

Osiris is a free portal creation software. The portals created with Osiris don't need a central server; they are safe, indestructible and anonymous. In those portals, all users have the same rights, so the standard hierarchies (administrators, moderators, members) of regular forums are not present, even if they are supported.
