Akkoma

Akkoma is a specialised fork of Pleroma that implements the ActivityPub protocol to operate as a federated social network. It emphasizes expressive posting (Misskey-flavored markdown, rich reactions) and supports multiple frontends and compatibility with other fediverse servers.

Key Features

• Implements ActivityPub for federation with other fediverse services.
• Misskey-flavoured Markdown and rich post formatting for animated/rich markup.
• Custom emoji reactions and unlimited attachments per post.
• Multiple frontends supported (default Pleroma-FE plus optional Mastodon-style frontend and third-party frontends).
• Unlimited post edits, quoting, polls, and list-based timeline customization.
• Performance and operational tooling: Elixir/Phoenix-based backend, PostgreSQL, background job processing and S3-compatible uploads; Docker and docker-compose resources are provided for deployment and testing.

Use Cases

• Host a community-oriented federated social network instance with expressive post features.
• Experiment with fediverse UX and frontends (Mastodon-style and Pleroma/Akkoma-specific frontends).
• Migrate or fork existing Pleroma installations to a project with faster development cadence and additional formatting/reaction features.

Limitations and Considerations

• Real-time chat functionality was deliberately removed compared to some Pleroma forks; Akkoma focuses on ActivityPub timeline and posting features rather than integrated chat.

Akkoma is a developer- and community-driven Elixir/Phoenix project intended for operators who want an expressive, ActivityPub-compatible server with multiple frontend options and performance-focused improvements. It is maintained with tooling and deployment resources (Docker, compose, nginx config and CI) to support instance operators and contributors.
