From Fluxer’s updated roadmap on their website

See the polyproto website they linked here

I hadn’t heard of this protocol before, but the possibility of transferring accounts between homeservers sounds exciting!

Here’s the text from the screenshot:

Federation lets people on different instances talk to each other as if they were on the same service, the way email works across providers. Fluxer’s federation will be based on polyproto-core, a specification from the polyproto project, with our own extensions on top. polyproto is still young, and we hope that building a real implementation of it, and sharing what we learn, helps the specification mature and benefits everyone else who builds on it.

polyproto-core describes an identity that works across servers. Your identity is anchored on your home server and looks like name@domain. Behind it is a certificate that your home server signs over a key created on your device. To prove who you are to another server, your device signs a challenge from that server, so one identity works across servers and you don’t need a separate account on each. Messages are signed by the sender, so a server you visit can’t forge messages from you without being detected, as long as your home server and your device haven’t been compromised. The specification also defines how to move to a new home server.

polyproto-core is an early beta specification maintained by the Polyphony project. As of October 2026 it is at v1.0-beta.13. It focuses on identity and leaves message formats and chat features to extensions. We’ll write our own extensions for Fluxer’s features and propose changes to the protocol where they would help others too.

We’ll publish an experimental draft pull request in 2026 that you can try and give feedback on. The stable release follows in 2027. Until the draft is up, the discussion happens in Fluxer Labs, and you’re welcome to join in.

You can already sign in to several instances from one app. You sign in to each instance separately and switch between them. The mobile apps already support several instances and accounts, and the desktop app gets the same in early October 2026 with the update described in #2.

    It doesn’t look like this at all for me. Maybe it’s an issue of mobile web client? I went to the website and logged in. I don’t see a plus like on discord to join servers or guilds so I assume there is nothing like that. I only saw the rooms I am in on matrix and it looked pretty much like the othet matrix clients I use.

    Your screenshot looks way more like discord.

    But so does fluxer and I found it less confusing and more immediately obvious to use compared to this.
