Lemmy
App in the BluixApps catalog
What it is
Lemmy is a federated link aggregator — think Reddit, but over ActivityPub. Self-host your own instance, federate with others to form a network that's resistant to single-point control. Communities ("sublemmys") instead of subreddits, votes propagate across instances, profiles portable.
Built in Rust for performance. The Fediverse's answer to Reddit's API rebellion.
What it's for
- Niche community hosting — a focused community without Reddit's policies
- Federated discussion — connect to other Lemmy + Mastodon instances
- Privacy-respecting forums — no algorithmic feed manipulation, no ads
- Open governance — community moderators, transparent rules
- API access — third-party apps and bots work natively
Who it's for
- Community builders rejecting Reddit's API closure
- Open-source projects hosting their own discussion forum
- Privacy advocates moving off centralized platforms
- Fediverse enthusiasts running federated nodes
- Hosting providers offering a community platform to clients

Tips & operations
- HTTPS required for federation — IP-only deployments can't federate; use DNS + cert
- pict-rs — required for image uploads; configure persistent volume
- Federation key signing — generated on first start; back up the config
- Postgres tuning — busy instances need shared_buffers + work_mem tuned
- Moderation tooling — bots/scripts for spam mitigation are essential at scale
- Defederation policy — document your stance on hate-speech instances early
