I mentioned in my Nerimity thread that I've been looking at a few different Discord alternatives. Another chat client that I've been trying out is Revolt, and the cool thing about this one is that you can install different themes just like on a forum, to really make the client look better. Though you can only have one theme installed at a time unfortunately, but it's much more than what you can do with Discord and it's 100% free. I'm still getting used to things on Revolt, but if you're looking for a Discord alternative I highly recommend checking out Revolt. Currently there's only a web client, Windows/Linux, and Android but I don't believe there's an app for iOS yet.
