This is a list of federated social clients and other related tools that use protocols other than those used in the fediverse (OStatus, ActivityPub, Diaspora, DFRN, Zot)
[SSB (Secure Scuttlebutt)](https://www.scuttlebutt.nz/) is a distributed networking protocol based on [DAT](https://www.datprotocol.com/), see also: https://datproject.org/
* [Manyverse](https://www.manyver.se/) is an SSB client for Android/Linux.
* [Patchwork](https://github.com/ssbc/patchwork/)is an SSB client for desktop platforms (currently supporting GNU/Linux, MacOS, and Windows).
#### XMPP
* [Movim](https://movim.eu) is a web client with social network features, written in PHP and uses ~~eJabberd (Erlang) backend~~ any XMPP server with [XEP-0060 PubSub](https://xmpp.org/extensions/xep-0060.html) support. Users can login to any Movim instance using any XMPP account, just as they can login to any Pinafore instance using any Mastodon account.
* [Salut à Toi](http://salut-a-toi.org/) (includes the Libervia web client) is a social network based on XMPP/Jabber.
This list may need its own page, because although all these apps are all distributed, because they use a blockchain, but not federated. I think it's useful to have this list to point to, in case people think we just don't know about these apps, and because the non-scammy free code ones might be worth approaching about implementing AP or Zot to bridge to the fediverse.
Unlike the fediverse apps, because they are all in competition with each other, it's hard to see how any of them will gain the network effect to compete with the legacy datafarms. Although some, like Resonate and Muscioin, are [platform cooperatives](https://www.opendemocracy.net/oliver-sylvester-bradley/ours-to-hack-and-own), it seems like at least some of the others are just datafarm larvae like [Everipedia](https://davidgerard.co.uk/blockchain/2018/10/13/everipedia-the-wikipedia-for-being-wrong-but-on-the-blockchain/), aiming to enslave enough users to get Vulture Capitalist funding, and exit by acquisition or IPO - Strypey
* [Leeroy](https://leeroy.io/) (defunct) - a web-based social network app that used the Ethereum blockchain. Their website now directs users to Peepeth.
* [Minds](http://minds.com/) - an unmoderated web-based social network app that uses the Ethereum blockchain.
* [Mycelia](http://myceliaformusic.org/) - a social network for musicians founded by Imogen Heap, planning a Creative Passport app using a blockchain and smart contracts
* [Numaverse](https://numaverse.com/) (defunct?) - a web-based social network app that uses the Ethereum blockchain. Was planning to bridge with AP networks. May be abandoned due to competition from Peepeth and Minds.
* [Peepeth](https://peepeth.com/) - a moderated web-based social network app that uses the Ethereum blockchain.
* [Steemit](https://steemit.com) - a web-based social network app (Slashdot/Reddit-a-like with up/down voting) that uses the Steem blockchain.
* [Twister](http://twister.net.co/) - a birdsite clone using its own blockchain (?)
