Mastodon has a ton of apps and Lemmy app development is going crazy right now. Are there any apps that can use both Lemmy and Mastodon accounts (and preferably Kbin accounts too)? I know the interfaces may need to be different, but the protocols are the same as far as I understand it, so it seems technically possible.
+1 for Fedilab It could use some improvements, but I am quite happy with it being able to look at multiple servers and follow different user from a single place.
