What is Lemmy?

Lemmy is a self-hosted social link aggregation and discussion platform. It is completely free and open, and not controlled by any company. This means that there is no advertising, tracking, or secret algorithms. Content is organized into communities, so it is easy to subscribe to topics that you are interested in, and ignore others. Voting is used to bring the most interesting items to the top.

Major Changes

A full list of fixes is below, but this patch release includes federation compatibility and bug fixes, as well as fixing vulnerabilities in our websocket rate limiting.

Upgrade notes

Besides the addition of a search rate limit to the lemmy.hjson, there are no config or API changes.

Follow the Docker or Ansible upgrade instructions here.

Support development

We (@dessalines and @nutomic) have been working full-time on Lemmy for almost two years. This is largely thanks to support from NLnet foundation. If you would like to support our efforts, please consider donating.

If you’d like to support development, and make sure that we will always be available to work full time on Lemmy, consider donating to support its development. We’ve spent hundreds of hours on Lemmy, and would like to be able to add more developers to our little open-source co-op as time goes on.

Thanks a lot for the hard work ! Always nice to read new federation improvements, might get used to it 😁


That’s a lot of improvements!
Thank you a lot and congratulations on yet another great release! Will be updating my instance very soon ;)

Plz make video guide “how to edit the UI, make a docker image and deploy it to the cloud server.” It’s just unbearable. I’ve been fucking with this shit for the second week, I already hate this shit.


None of that has anything to do with lemmy, that is basic docker stuff. You can ask how to do those things on a docker support site, or stackoverflow.

In this case, your project will remain only for Linux geeks :(

Sadly this is how hosting these kinds of services works at the moment. There is no way the devs can change this. If it helps you it’s not actually that hard, like @dessalines@lemmy.ml already said there are many step by step tutorials that will be great introductions into the world of system administration.

Well, I don’t know if that’s really sad, I think people should have a minimum of knowledge to host online services. Doing it while learning system administration from scratch and hoping it will be easy is kind of naive.

I did not read the docs but if it’s not the case maybe some basic knowledge should be listed as requirement along with some links to tutorials?

Unfortunately, most step-by-step tutorials assume knowledge of many basic things, which are not always even mentioned. For example, recently one of the users tried to explain to me that you just need to use the command "docker build -t lemmy-ui. " and etc., but there is a funny problem: I didn’t even understand where (in which environment or in which program) I can use it, and where I can’t. And also what to do after.

And so everything turns into collecting a million needles in a haystack. Of course, I understand that this is an integral part of learning everything related to programming. But often life works in such a way that one person, a professional in his field, can spend 4 hours of his time, saving 400 hours for 100 beginners. At the same time, without such help from a professional, probably 95% of potential active users and novice developers can simply get stuck and abandon their interest.

yes you are 100% correct, sorry. I don’t really know of any system administration tutorials for total beginners. We all learned this organically somehow, how to deal with ssh. We were bloody beginners who did stupid mistakes as well in the past, I used to always break my linux installs :D


If you need a video to learn basic docker, I’m sure there are many on youtube.

Lemmy is no different from other self hosted services, they all require some linux knowledge, but lemmy is comparatively easy to install. Look at pixelfeds install instructions if you want to see how complicated some can get.

Some services (like friendica) can be used with yunohost which is supposed to make self hosting easier, maybe we can try to encourage the community to add lemmy to it (and link to it on the lemmy homepage).

You already can install Lemmy with yunohost: https://github.com/YunoHost-Apps/lemmy_ynh . The app could use some love though.

The docs list it as “broken”.


Wow i had no idea. Looks like it could easily take a day to install with all those steps.
