I created a repo on GitHub that has a table comparing all the known lemmy instances

Why?

When I joined lemmy, I had to join a few different instances before I realized that:

  1. Some instances didn't allow you to create new communities
  2. Some instances were setup with an allowlist so that you couldn't subscribe/participate with communities on (most) other instances
  3. Some instances disabled important features like downvotes
  4. Some instances have profanity filters or don't allow NSFW content

I couldn't find an easy way to see how each instance was configured, so I used lemmy-stats-crawler and GitHub actions to discover all the Lemmy Instances, query their API, and dump the information into a data table for quick at-a-glance comparison.

I hope this helps others with a smooth migration to lemmy. Enjoy :)

I'm a little bit confused by the federation thing. How would I let my instance talk to any other instance except the ones I blacklist?

It's documented here:

By default users on an instance will be able to talk with communities/users on all other instances. This only changes if the instance admin puts hosts in the allowed list or disables federation.

If you add instances to the blocked list then users will be able to talk with all other instances, except those on the blocked list
