Misskey
With 11,000+ GitHub stars and over 1,291 releases since 2016, Misskey is the most feature-rich open-source microblogging platform in the Fediverse — federation-first social networking with capabilities that go far beyond simple status updates. The TypeScript and Vue 3 frontend delivers a highly customizable interface with drag-and-drop widget layouts, switchable themes, per-user custom CSS, and AiScript-powered plugins that transform every instance into a unique social experience. ActivityPub federation enables seamless interaction with Mastodon, Pixelfed, PeerTube, and any ActivityPub-compatible platform across the decentralized network. Emoji reactions let users respond with custom instance emojis instead of simple likes, while Misskey Flavored Markdown adds animated text effects, sparkle decorations, and rich formatting to posts. The built-in Drive provides personal cloud file management with folder organization for images, videos, and audio — eliminating the need for external storage services. Antennas create custom filtered timelines based on keywords, users, or criteria for monitoring specific topics. Channels offer topic-specific feeds separate from the main timeline. Pages enable users to build personal websites directly within their instance. Clips save and organize posts into curated collections. The Node.js backend scales with PostgreSQL for persistence, Redis for caching, and optional S3-compatible storage for media. Docker Compose deployment provisions the complete stack including the database and cache in under 15 minutes. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.
