Pleroma (software)

Pleroma is a free and open-source self-hosted distributed social networking and microblogging service. It implements the ActivityPub protocol (and formerly, OStatus),
https://medium.com/we-distribute/activitypub-support-lands-in-pleroma-96635b7d6fde making Pleroma instances part of the wider Fediverse, an interconnected and decentralized network of independently operated servers.
Like other Fediverse instances, independently hosted servers running Pleroma (referred to as "instances") provide a federated microblogging experience to netizens, similar to Twitter or Weibo. Users can post, follow, and interact with other users across Pleroma and non-Pleroma instances (Mastodon, PeerTube, Friendica, etc.) seamlessly.
Instance operators manage their own code of conduct, terms of service, and moderation policies, allowing users to settle on and roam instances, and browse content accordingly.

Pleroma was originally just a client-side alternative for the GNU social frontend Qvitter,

which resembled an earlier Twitter user interface.
Since then, a backend implementation of OStatus and ActivityPub was written in Elixir and the Phoenix framwork, and built with PostgreSQL. 
The frontend, now referred to as Pleroma-FE, is written with the Vue.js JavaScript framework.

Pleroma also provides the Mastodon frontend,

and an alternative Gopher frontend.

Pleroma is described as being less bloated than alternatives like Mastodon, having fewer software dependencies, and less resource intensive.

Pleroma dropped support for the older OStatus protocol in early 2020 in their v2.0.0 release, due to its declining use and buggy code.

As of mid 2020, Pleroma is the second most popular Fediverse server software behind Mastodon, according to fediverse.network, with about 13% share of all instances, and about 1% of Fediverse "users".

== Functionality and features ==
Pleroma instances run software that communicates with the ActivityPub protocol.
This connects Pleroma users to any other Fediverse software server that supports ActivityPub.
Pleroma's default, configurable post length limit is 5000
It is capable of uploading and sharing multimedia posts, as well as polls.
