Decentralized Reddit‑style link aggregator for the Fediverse
Lemmy lets you run your own Reddit‑like forum server that federates across the Fediverse, offering mobile‑friendly UI, voting, comments, moderation, and full self‑hosting via Docker or Ansible.
Lemmy provides a Reddit‑style link aggregation and discussion platform that operates across the Fediverse. Users register on any Lemma server and can subscribe to communities hosted anywhere in the network, enabling seamless cross‑server interaction while each instance retains its own moderation policies.
Ideal for developers, hobbyists, and organizations that want full control over their community data and governance. The service runs on a Rust backend and can be launched with a single Docker compose file or automated with Ansible, supporting both x86_64 and arm64 hardware such as Raspberry Pi. Once deployed, the responsive web UI offers live‑updating comment threads, voting, tagging, image uploads, and multiple themes, with optional email notifications and RSS/Atom feeds.
Because Lemmy is AGPL‑licensed, there are no ads or vendor lock‑in, and contributions from the global community continuously add features such as emoji autocomplete, private messaging, and NSFW content handling. The platform’s modular design also allows operators to integrate custom authentication providers or extend the API for specialized use‑cases.
