Lemmy

Powering over 496 instances with more than 35,000 monthly active users and 26,500 communities, Lemmy has established itself as the leading open-source, federated link aggregation platform in the Fediverse. Built entirely in Rust for memory-safe, high-performance server operation, Lemmy enables anyone to run their own Reddit-style community that automatically connects with every other Lemmy instance — and compatible ActivityPub platforms like Mastodon, PieFed, and Kbin — through standardized federation protocols. Users create and subscribe to topic-based communities, submit posts containing text, links, or images, engage through threaded comment discussions, and shape content visibility through upvote/downvote mechanisms. Instance administrators retain full control over moderation policy, federation allowlists and blocklists, site appearance, and user registration settings, while community moderators can sticky posts, lock threads, ban users, and maintain public moderation logs for transparency. The platform supports private messaging between users, email notifications, RSS and Atom feed generation for every community, comprehensive internationalization with dozens of language packs, custom emoji support, and both light and dark themes through a clean mobile-responsive interface. Deployment is straightforward with official Docker Compose configurations and Ansible playbooks, backed by a PostgreSQL database with pict-rs for image hosting. Lemmy's Rust backend consistently benchmarks among the most efficient Fediverse server implementations, enabling small VPS instances to serve thousands of users. 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.
