When you go to the domain of your instance (lemmy.world), you get the official Lemmy UI hosted in their servers. Other people can make their own UIs tho and host it on their servers or let you download them as apps. One alternative UI that you can use in a browser is phtn.app.

If you’re on a desktop alexandrite.app’s 2-column view is great.
