Akkoma - Magically Expressive Social Media | WarmIndex

Akkoma is a decentralized fediverse microblogging platform and server software, forked from Pleroma, designed for users and administrators seeking expressive, high-performance social networking without central authority.

🚀 Overview

Akkoma is a federated social media server that implements the ActivityPub protocol, allowing users to post, follow, and interact across the entire fediverse—including Mastodon, Misskey, and other compatible platforms—while running on your own server or joining an instance like akkoma.social.

This project solves the problems of centralized social networks like Twitter/X by providing decentralization, user control over data, no corporate oversight, and enhanced expressiveness through features like custom emoji reactions and advanced markdown.

It's built for fediverse enthusiasts, self-hosters, developers, and anyone wanting a more customizable and performant alternative to slower-developing Pleroma. The fork was created due to Pleroma's stagnant development, aiming for a faster pace with experimental features inspired by Misskey.

✨ Key Features

Custom emoji reactions (Misskey-compatible) and Misskey-flavored markdown for fancy animations and expressive posts
Post with unlimited attachments (photos, videos), edit posts any number of times, quote posts, and create polls
30-50% speed improvement over Pleroma, with support for Elasticsearch/Meilisearch search and automatic post translation (DeepL/LibreTranslate)
Mastodon client API compatibility with Pleroma extensions, plus support for multiple frontends like Glitch-Soc and Fedibird
Optional: Instance clustering ('bubbles'), stronger domain blocking, and extensive Pleroma frontend modifications

🛠 Tech Stack
