A link aggregator / reddit clone for the fediverse.

Lemmy Dev instance This data is being backed up, and once federation is working, it will be the basis for a main instance.

This is a very early beta version, and a lot of features are currently broken or in active development, such as federation.

Front Page Post
main screen chat screen

Lemmy is similar to sites like Reddit,, Raddle, or Hacker News: 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.

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.

Made with Rust, Actix, Inferno, Typescript and Diesel.


  • Open source, AGPL License.
  • Self hostable, easy to deploy.
  • Clean, mobile-friendly interface.
    • Live-updating Comment threads.
    • Full vote scores (+/-) like old reddit.
    • Themes, including light, dark, and solarized.
    • Emojis with autocomplete support. Start typing :
    • User tagging using @, Community tagging using #.
    • Notifications, on comment replies and when you're tagged.
    • i18n / internationalization support.
    • RSS / Atom feeds for All, Subscribed, Inbox, User, and Community.
  • Cross-posting support.
    • A similar post search when creating new posts. Great for question / answer communities.
  • Moderation abilities.
    • Public Moderation Logs.
    • Both site admins, and community moderators, who can appoint other moderators.
    • Can lock, remove, and restore posts and comments.
    • Can ban and unban users from communities and the site.
    • Can transfer site and communities to others.
  • Can fully erase your data, replacing all posts and comments.
  • NSFW post / community support.
  • High performance.
    • Server is written in rust.
    • Front end is ~80kB gzipped.
    • Supports arm64 / Raspberry Pi.

Why's it called Lemmy?



Make sure you have both docker and docker-compose(>=1.24.0) installed:

mkdir lemmy/
cd lemmy/
# Edit lemmy.hjson to do more configuration
docker-compose up -d

and go to http://localhost:8536.

A sample nginx config, could be setup with:

# Replace the {{ vars }}
sudo mv nginx.conf /etc/nginx/sites-enabled/lemmy.conf


To update to the newest version, run:

docker-compose up -d


First, you need to install Ansible on your local computer (e.g. using sudo apt install ansible) or the equivalent for you platform.

Then run the following commands on your local computer:

git clone
cd lemmy/ansible/
cp inventory.example inventory
nano inventory # enter your server, domain, contact email
ansible-playbook lemmy.yml --become
