We just added Alexandrite to the server, it's an alternative desktop UI for Lemmy created by Sheodox who worked tirelessly to make the necessary changes to we could host it ourselves here. So go to https://a.lemmy.world and have a look!
He continues to update it constantly, you can follow the development on his github page or in his community. If you like what you see and want to support him, why not buy him a coffee? :)
For those who don't have Lemmy World as their home instance and want to use Alexandrite, either ask your instance admins to add it or go to https://alexandrite.app!
Edit: I should probably have mentioned that Alexandrite is meant for desktop!
Yep, loved it so much I contacted @sheodox@lemmy.world to help us add it to the instance. He added some changes to Selfhost, put it all in a docker container and made it all happen in a couple of days ā¤ļø
I'm sure more admins will be adding it to their instance!
