Fluxer: A chat app that puts you first
fluxer.app
Fluxer is a free and open source instant messaging and VoIP platform built for friends, groups, and communities.

Since Discord has decided to set itself on fire you might be looking for an alternative. Fluxer is open source (AGPL), selfhostable and based in Sweden. But maybe wait a while before you try to install the server yourself because the dev writes on github:

I know it’s hard to resist, but please wait a little longer before you dive deep into the current codebase or try to set up self-hosting. I’m aware the current stack isn’t very lightweight. In the next update, self-hosting should be straightforward, with a small set of services: Fluxer Server (TypeScript) using SQLite for persistence, Gateway (Erlang), and optionally LiveKit for voice and video.

The developer hosted instance has a Nitro-like premium tier for their service named Plutonium, if you selfhost you get all the premium features for free.

Fluxer is not federated (yet), but according to the website, federation is planned in the near(-ish) future. Furthermore the service is a bit spotty at the moment as they are fighting with an unusually big influx of new users.

      A mastodon post by a user named June, @June@wolfd(here it’s truncated due to length) Transcript:

      Have you seen the new chat platform? It’s on Stoat. It’s literally on Fluxer. It’s on Discord with ads. It’s literally on Root. You can probably find it on Spacebar. Dude it’s on Squirrel Chat. It’s a Rocket chat original. It’s on TeamSpeak 3. You can collaborate on Chanty. You can go to Twist and work on it. Log onto Wire right now. Go to Viber. Dive into Zangi. You can Zulip it. It’s on Pumble. Osmium has it for you. DCTS has your back. You can use Jitsi. You can get it with Chatmail. It’s a discourse exclusive. Nanochat it right this second.

      In all seriousness, try out Fluxer. It’s FOSS and they promise federation in the future.
