## About The Project

![main screen](https://i.imgur.com/kZSRcRu.png)|![chat screen](https://i.imgur.com/4XghNh6.png)

[Lemmy](https://github.com/dessalines/lemmy) is similar to sites like [Reddit](https://reddit.com), [Lobste.rs](https://lobste.rs), [Raddle](https://raddle.me), or [Hacker News](https://news.ycombinator.com/): you subscribe to forums you're interested in, post links and discussions, then vote, and comment on them. Behind the scenes, it is very different; anyone can easily run a server, and all these servers are federated (think email), and connected to the same universe, called the [Fediverse](https://en.wikipedia.org/wiki/Fediverse).

For a link aggregator, this means a user registered on one server can subscribe to forums on any other server, and can have discussions with users registered elsewhere.

The overall goal is to create an easily self-hostable, decentralized alternative to reddit and other link aggregators, outside of their corporate control and meddling.

Each lemmy server can set its own moderation policy; appointing site-wide admins, and community moderators to keep out the trolls, and foster a healthy, non-toxic environment where all can feel comfortable contributing.

*Note: Federation is still in active development*
