About Lemmy
Lemmy is a link aggregator and forum platform for the Fediverse, written in Rust and released under the AGPL 3.0 license. It supports communities where users subscribe to forums, post links and discussions, vote, and comment. Each server can operate independently while remaining federated through ActivityPub, so users on one server can interact with users and communities on other servers.
