Lemmy is similar to sites like Reddit, Lobste.rs, or Hacker News but it's open source, it's federated with the Fediverse, and zero lock in

You subscribe to communities you're interested in, post links and discussions, then vote and comment on them. Lemmy isn't just a reddit alternative; its a network of interconnected communities ran by different people and organizations, all combining to create a single, personalized front page of your favorite news, articles, and memes.
Each server can set its own moderation policy, to help foster a healthy environment where all can feel comfortable contributing.
With Lemmy, you can easily host your own server, and all these servers are federated (think email), and connected to the same universe, called the Fediverse. For a link aggregator, this means that someone registered on one server can subscribe to communities elsewhere, and can have discussions with people on a completely different server.
Lemmy is free, open-source software, meaning no advertising, monetizing, or venture capital, ever.
