Friendica (formerly Friendika, originally Mistpark) is a free and open-source software [5] distributed social network. It forms one part of the Fediverse, an interconnected and decentralized network of independently operated servers. [6] [7] [8]
Friendica users can connect with others via their own Friendica server, but may also fully integrate contacts from other platforms including Twitter, Diaspora, Pump.io, GNU social, email, Discourse [9] and more recently ActivityPub (including Mastodon, Pleroma and Pixelfed) and Bluesky [10] [11] into their 'newsfeed'. In addition to these two way connections, users can also use Friendica as a publishing platform to post content to WordPress, Tumblr, Insanejournal [12] and Libertree. Posting to Google+ was also supported until that service was shut down. In addition, RSS feeds can be ingested. [13] Because users are distributed across many servers, their "addresses" consist of a username, the "@" symbol, and the domain name of the Friendica instance in the same manner email addresses are formed.
Most of the functionality from major microblogging and social networking platforms are available in Friendica; for example, tagging users and groups via "@ mentions"; direct messages; hashtags; photo albums; "likes"; "dislikes"; comments; and re-shares of publicly visible posts. Published items can be edited and updated across the network. Comprehensive settings for privacy and the public visibility of posts allow users to regulate who can read which contributions, or see specific information about the user. Users can also create multiple profiles, allowing different groups of people (such as friends, or work mates) to see a different profile entirely when viewing the same page. User accounts can be downloaded or deleted, and can be imported to a different Friendica server if so required. [13] Public forums can be created under different accounts, which can be switched between if the accounts are registered with the same email address. [14]
There is no corporation behind Friendica. The developers work on a voluntary basis and the project is run informally, the platform itself is used for the communication between the developers. [15] There are different forums within Friendica, such as "Friendica Developers" [16] and "Friendica Support". [17] The source code of Friendica is hosted on GitHub. [18] [19]
The developers aim to make installation of the software as simple as possible for technical laymen. They argue that decentralization on small servers is a key condition for the freedom of users and their self-determination. The difficulty level is similar to an installation of WordPress. However, the installing on shared hosting is sometimes difficult because of missing PHP5 modules. Some volunteers also run public servers so that newcomers can also avoid the installation of their own software. [20]
Friendica implements multiple client-server API variants simultaneously. Along with endpoints needed to use enhanced Friendica features, it also implements the API used by GNU social, Twitter and since version 2021.06 also the one used by Mastodon. As a result, most GNU social and Mastodon clients can be used for Friendica. [21] Examples of Friendica compatible clients include: Friendiqa, Fedilab, AndStatus, Twidere and DiCa for Android, friendly for Sailfish OS, friclicli (CLI client), choqok and Friendiqa for Linux and Friendica Mobile for Windows 10. [22]
Friendica was cited in January 2012 by Infoshop News as an "alternative to Google+ and Facebook" to be used on the Occupy Nigeria movement. [23] In January 2012 Free Software Foundation Europe's blog cited Friendica as a reasonable alternative to centralized and controlled social networks such as Facebook or Google+. [24] Biblical Notes writer J. Randal Matheny described Friendica in January 2012 as "One social networking option flying under the radar until recently deserves consideration as an already stable platform with a wide range of options, applications, plug-ins, and possibilities for opening up the Internet." [25] In February 2012, the German computer magazine c't wrote: "Friendica demonstrates how decentralized social networks can become widely accepted." [26] Another German publication, the professional magazine t3n listed Friendica as a Facebook rival in an online article in March 2012 about Facebook alternatives. It compared Friendica with similar social networks like Diaspora and identi.ca. [27] MSN Tech & Gadgets contributor Emma Boyes wrote about Friendica in May 2012: "why you'll love it: you can use it to access all the other social networks and get recommendations of new friends and groups to join. Friendica is open source and decentralised. There's no corporation behind it and there are extensive privacy settings. You can choose from a variety of user interfaces and it boasts some cool features - for instance, being able to key in a list of your interests and use the 'profile match' feature to recommend other users who share them with you. A word of warning, though, the site is not as user-friendly as the others on this list, so it may be this one is one for the geeks." [28]
Acquisition of Twitter by Elon Musk had revitalized public interest in Fediverse technologies in April 2022. Friendica received favorable reviews, with a PCMag article describing it as "mostly comparable to Facebook", drawing a parallel to Google+ and highlighting using it "for planning events, and its multiple profile feature means you can show a different face to your friends, coworkers, and family". [29]
The September 2022 issue of Linux Magazine contains a detailed comparison and walk-through of registering to and using basic functions of Diaspora, Friendica and Mastodon. They describe Friendica as "intuitive" and highlight the "huge choice of account settings" and that "Friendica does not require any specific hardware, so you can use an old computer system as a server." [30]
In September 2020, a hotfix was released to patch a security vulnerability that could leak sensitive information from the server environment since versions released in April 2019 (develop branch) and June 2019 (stable). [31]
Gnutella is a peer-to-peer network protocol. Founded in 2000, it was the first decentralized peer-to-peer network of its kind, leading to other, later networks adopting the model.
BitlBee is a cross-platform IRC instant messaging gateway, licensed under the terms of the GNU General Public License.
Microblogging is a form of blogging using short posts without titles known as microposts. Microblogs "allow users to exchange small elements of content such as short sentences, individual images, or video links", which may be the major reason for their popularity. Some popular social networks such as Twitter, Mastodon, Tumblr, Koo, and Instagram can be viewed as collections of microblogs.
GNU social is a free and open source software microblogging server written in PHP that implements the OStatus standard for interoperation between installations. While offering functionality similar to Twitter, GNU social seeks to provide the potential for open, inter-service, and distributed communications between microblogging communities. Enterprises and individuals can install and control their own services and data.
The tables below compare general and technical information for some notable active microblogging services, and also social network services that have status updates.
WebFinger is a protocol specified by the Internet Engineering Task Force IETF in RFC 7033 that allows for discovery of information about people and things identified by a URI. Information about a person might be discovered via an acct: URI, for example, which is a URI that looks like an email address.
Diaspora is a nonprofit, user-owned, distributed social network. It consists of a group of independently owned nodes which interoperate to form the network. The social network is not owned by any one person or entity, keeping it from being subject to corporate take-overs or advertising. According to its developer, "our distributed design means no big corporation will ever control Diaspora."
OStatus is an open standard for federated microblogging, allowing users on one website to send and receive status updates with users on another website. The standard describes how a suite of open protocols, including Atom, Activity Streams, WebSub, Salmon, and WebFinger, can be used together, which enables different microblogging server implementations to route status updates between their users back-and-forth, in near real-time.
Distributed social network projects generally develop software, protocols, or both.
F-Droid is an app store and software repository for Android, serving a similar function to the Google Play store. The main repository, hosted by the project, contains only free and open source apps. Applications can be browsed, downloaded and installed from the F-Droid website or client app without the need to register for an account. "Anti-features" such as advertising, user tracking, or dependence on non-free software are flagged in app descriptions.
Movim is a distributed social network built on top of XMPP, a popular open standards communication protocol. Movim is a free and open source software licensed under the AGPL-3.0-or-later license. It can be accessed using existing XMPP clients and Jabber accounts.
PeerTube is a free and open-source, decentralized, ActivityPub federated video platform powered by WebTorrent, that uses peer-to-peer technology to reduce load on individual servers when viewing videos.
Mastodon is a free and open-source software for running self-hosted social networking services. It has microblogging features similar to Twitter, which are offered by a large number of independently run nodes, known as instances or servers, each with its own code of conduct, terms of service, privacy policy, privacy options, and content moderation policies.
The fediverse is an ensemble of social networks which can communicate with each other, while remaining independent platforms. Users on different social networks and websites can send and receive updates from others across the network.
Micro.blog is a microblogging and social networking service created by Manton Reece. It is the first large multi-user social media service to support the Webmention and Micropub standards published by the World Wide Web Consortium, and is part of the Fediverse, supporting ActivityPub.
ActivityPub is an open, decentralized social networking protocol based on Pump.io's ActivityPump protocol. It provides a client/server API for creating, updating, and deleting content, as well as a federated server-to-server API for delivering notifications and content.
Pixelfed is a free and open-source image sharing social network service. It is decentralized, therefore user data is not stored on a central server, unlike other platforms. Pixelfed uses the ActivityPub protocol which allows users to interact with other social networks within the protocol, such as Mastodon, PeerTube, and Friendica. Using this protocol makes Pixelfed a part of the Fediverse. The network is made up of several independent sites that communicate with one another, which is roughly comparable to e-mail providers. The parties involved do not all have to be registered with the same provider, but can still communicate with each other. Thus, users are able to sign up on any server and follow others on the other instances.
Bluesky, also known as Bluesky Social, is a microblogging social platform and a public benefit corporation based in the United States. Jay Graber serves as the company's CEO, while Twitter co-founder Jack Dorsey and XMPP creator Jeremie Miller sit on its board of directors.
Eugen Rochko is a Russian-born German software developer, best known as the creator of Mastodon, a decentralized open-source social networking platform consisting of a large number of independently run nodes, known as instances, each with its own code of conduct, terms of service, privacy policy, privacy options, and moderation policies.
