What is Fluxer?
Fluxer is an open-source platform for instant messaging and VoIP communications, designed to facilitate interaction among friends, groups, and communities. Users can direct message, participate in group chats, and create communities through organized channels. It supports Markdown in messages, file sharing, link previews, and allows for multi-device calls with screen sharing, noise suppression, and echo cancellation.
Fluxer provides moderation tools including roles, permissions, audit logs, webhooks, and bots support. It features a search function, a quick switcher for easy navigation, and options to manage friends and block users.
Users can customize Fluxer by uploading emojis, stickers, and saving media for later use. The app can be styled with custom CSS themes and offers display options. Fluxer can be self-hosted on personal hardware and is open source under the AGPLv3 license. It has a desktop client, with a mobile version under development. Users can switch between multiple instances.














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"

So, unless you're into bdsm and you like getting blocked and banned by people who can't think and are extremely emotional then maybe this is the app for you.
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.
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.
