Every package Lemmy depends on, ranked by repo health score.
Lemmy is an open-source, federated link aggregator and discussion platform built for the Fediverse. It gives anyone the ability to run their own forum server — hosting communities, setting moderation policies, and owning all content — without depending on a corporation or third-party cloud service. Users on one Lemmy instance can subscribe to communities and interact with users on any other federated instance, just like email works across providers.
Under the hood, Lemmy is a Rust monorepo with clearly separated crates for API, federation (ActivityPub), and database access. The backend runs on Actix Web with Diesel ORM over PostgreSQL, and a TypeScript client with auto-generated types keeps the API contract tight across the stack. An AGPL-3.0 license means all forks and modifications must remain open.
Lemmy is actively approaching its 1.0 release (in beta as of mid-2026) with features including a WASM plugin system via Extism, scheduled post publishing, cross-instance federation testing, and rate limiting with admin overrides. With over 14,000 GitHub stars, 253 contributors, and monthly releases, it is one of the most mature and actively maintained decentralized social platforms available.
