Misskey is a self-hosted, decentralized microblogging platform and federated social media server. It functions as a distributed content management system that allows users to communicate across multiple independent and interconnected server instances using the ActivityPub protocol.
The platform distinguishes itself with a dynamic application engine that allows for the creation of interactive applications and custom page layouts using a scripting language. It also features a specialized markup language for rich text rendering, enabling the use of animations and custom styles for consistent content presentation.
The system provides comprehensive capabilities for community management, including role-based access control, content moderation tools, and private messaging with configurable acceptance rules. It also includes full-text search for posts and profiles, server performance monitoring via interactive charts, and administrative command-line tools for system maintenance.
Users can secure their accounts using multi-factor authentication and passkeys, while administrators can manage the infrastructure through schema-based database migrations and orchestrated caching services.
