It would be almost effortless for even the most entrenched discord normie to navigate and use. The UI is almost 1:1. In fact, you can save your old discord channels template and import it into Fluxer effectively making a clone of your old setup instead of having to meticulously remake every category, channel, and permission manually.

Comments and Reviews
I like Fluxer because it is open source and self-hostable. But at the moment is pretty slow, which is probably linked to the recent Discord controversy.
rumors says it's vibecoded, it has been made on a rush since discord started to suck, and their main instance ToS/moderation are just baby crying type of stuff. has a subscription on their main instance which locks EXACTLY the same features as discord (which is pretty limiting already). they will also randomly lock your account entirely you and ask you for a phone number to "verify you're not a bot" if you're not prudent enough (yep, just like discord, again), which is already privacy-invasive. technically, it's just like discord, so there's no actual improvement. if you won't self-host fluxer, it's really not a good idea to use it.
(First of all I approve of the username) https://fluxer.app/blog/how-i-built-fluxer-a-discord-like-chat-app This above seems to be the official development blog post, it seems like Fluxer has been in development for roughly 5 years (as a hobby project). I will confirm the rumors that AI has been used.
The dev says: "I used LLMs sparingly as a troubleshooting and planning aid" "Fluxer isn't vibe-coded, describing it that way would be false and unfair to years of work"

It's like Discord, but without the age verification and data collection. It's also FOSS!
One of the best alternatives to Discord
100% It's similar to Discord, of course — it doesn't have all the features, but I like it. It has everything you need for communication, it's open-source, and they'll be adding federation and encryption soon.
I have a lot of hope for Fluxer, but being as new as it is it's currently struggling a lot with downtime issues. At least the dev gives more of a hoot than the Stoat dev seems to.
