This is a categorized list of notable onion services (formerly, hidden services)accessible through the Tor anonymity network. Defunct services are marked.
Crypto-anarchism is a political ideology focusing on protection of privacy, political freedom and economic freedom, the adherents of which use cryptographic software for confidentiality and security while sending and receiving information over computer networks.
A dark net or darknet is an overlay network within the Internet that can only be accessed with specific software, configurations, or authorization, and often uses a unique customized communication protocol. Two typical darknet types are social networks, and anonymity proxy networks such as Tor via an anonymized series of connections.
.onion is a special-use top level domain name designating an anonymous onion service, which was formerly known as a "hidden service", reachable via the Tor network. Such addresses are not actual DNS names, and the .onion TLD is not in the Internet DNS root, but with the appropriate proxy software installed, Internet programs such as web browsers can access sites with .onion addresses by sending the request through the Tor network.
Tor is free and open-source software for enabling anonymous communication by directing Internet traffic through a free, worldwide, volunteer overlay network consisting of more than seven thousand relays in order to conceal a user's location and usage from anyone conducting network surveillance or traffic analysis. Using Tor makes it more difficult to trace the Internet activity to the user: this includes "visits to Web sites, online posts, instant messages, and other communication forms". Tor's intended use is to protect the personal privacy of its users, as well as their freedom and ability to conduct confidential communication by keeping their Internet activities unmonitored.
Tails, or The Amnesic Incognito Live System, is a security-focused Debian-based Linux distribution aimed at preserving privacy and anonymity. All its incoming and outgoing connections are forced to go through Tor, and any non-anonymous connections are blocked. The system is designed to be booted as a live DVD or live USB, and will leave no digital footprint on the machine unless explicitly told to do so. The Tor Project provided financial support for its development in the beginnings of the project. Tails comes with UEFI Secure Boot.
GlobaLeaks is an open-source, free software intended to enable secure and anonymous whistleblowing initiatives.
The Hidden Wiki was a dark web MediaWiki wiki operating as Tor hidden services that could be anonymously edited after registering on the site. The main page served as a directory of links to other .onion sites.
The Associated Whistleblowing Press (AWP) is a not-for-profit information agency based in Brussels, Belgium, dedicated to the defense of human rights by promoting transparency, freedom of information and speech, whistleblowing and investigative journalism, conceived as a global network made up of cooperative local platforms and actors. According to its website, the initiative aims to work in a decentralized network structure, with local platforms that deal with local information, contexts and actors in a "from the roots upward model". The stories produced will then be published on the project's multilanguage newsroom under a Creative Commons license. The team consists of collaborators spread all around the world, led by two editors, Pedro Noel and Santiago Carrion.
SecureDrop is a free software platform for secure communication between journalists and sources (whistleblowers). It was originally designed and developed by Aaron Swartz and Kevin Poulsen under the name DeadDrop. James Dolan also co-created the software.
Lolita City was a website that used hidden services available through the Tor network. The site hosted child pornography images and videos of underage males and females ranging up to 17 years of age.
Freedom Hosting is a defunct Tor specialist web hosting service that was established in 2008. At its height in August 2013, it was the largest Tor webhost.
The dark web is the World Wide Web content that exists on darknets: overlay networks that use the Internet but require specific software, configurations, or authorization to access. Through the dark web, private computer networks can communicate and conduct business anonymously without divulging identifying information, such as a user's location. The dark web forms a small part of the deep web, the part of the Web not indexed by web search engines, although sometimes the term deep web is mistakenly used to refer specifically to the dark web.
Tor2web is a software project to allow Tor hidden services to be accessed from a standard browser without being connected to the Tor network. It was created by Aaron Swartz and Virgil Griffith.
Mirror sites or mirrors are replicas of other websites or any network node. The concept of mirroring applies to network services accessible through any protocol, such as HTTP or FTP. Such sites have different URLs than the original site, but host identical or near-identical content. Mirror sites are often located in a different geographic region than the original, or upstream site. The purpose of mirrors is to reduce network traffic, improve access speed, ensure availability of the original site for technical or political reasons, or provide a real-time backup of the original site. Mirror sites are particularly important in developing countries, where internet access may be slower or less reliable. The maintainers of some mirrors choose not to replicate the entire contents of the upstream server they are mirroring because of technical constraints, or selecting only a subset relevant to their purpose, such as software written in a particular programming language, runnable on a single computer platform, or written by one author. These sites are called partial mirrors or secondary mirrors.
Doxbin was a document sharing and publishing website which invited users to contribute personally identifiable information, or "dox", of any person of interest. It was previously operated on the darknet as a Tor hidden service, by a person known on the internet as nachash. Since its takedown in 2014, nachash has stepped down and relinquished his ownership to a predecessor that used the username "King Oren" when interviewed. He said in an interview that he is hosting Doxbin on the World Wide Web, as well as on Darknet and Tor hidden service websites. He declined to release the link to either of them, saying, "The people that use the service know how to find it, that's what keeps it secure and out of the reach of incompetent people using it for malice things".
Parrot OS is a Linux distribution based on Debian with a focus on security, privacy, and development. Parrot OS is also used by many penetration testers.
A darknet market is a commercial website on the dark web that operates via darknets such as Tor or I2P. They function primarily as black markets, selling or brokering transactions involving drugs, cyber-arms, weapons, counterfeit currency, stolen credit card details, forged documents, unlicensed pharmaceuticals, steroids, and other illicit goods as well as the sale of legal products. In December 2014, a study by Gareth Owen from the University of Portsmouth suggested the second most popular sites on Tor were darknet markets.
Grams is a discontinued search engine for Tor based darknet markets launched in April 2014, and closed in December 2017. The service allowed users to search multiple darknet markets for products like drugs and guns from a simple search interface, and also provided the capability for its users to hide their transactions through its bitcoin tumbler Helix.
facebookcorewwwi.onion is a site that allows access to Facebook through the Tor protocol, using its .onion top-level domain. In April 2016, it had been used by over 1 million people monthly, up from 525,000 in 2015. Neither Twitter nor Google operate sites through Tor, and Facebook has been applauded for allowing such access, which makes it available in countries that actively try to block Facebook.
torservers.net is an independent network of non-profit organisations that provide nodes to the Tor anonymity network. The network started in June 2010.
DSA announces Debian static websites are now available as Onion services. The list of services may be found on https://onion.debian.org .
The TOR/Onion address uj3wazyk5u4hnvtk.onion should also be fine longer term but it’s hardly the most memorable set of digits for anyone to recall.
