The story behind Fluxer View full roadmap

Host it yourself (or don't!)

Fluxer works out of the box on our servers. If you'd rather run your own, you can, and that server is yours.

How self-hosting works

Chat that keeps up

Talk one on one, in group chats, or in organized community channels. Messages support Markdown and code blocks, files and link previews, and your community's own emoji and stickers.

Jump into voice

Join a voice channel to talk, share your screen, or turn on your camera. You can connect from more than one device at once, and noise suppression and echo cancellation keep every call clear.

Your community, your rules

Give people roles with exactly the permissions they need. Time out, kick, or ban members when you have to, and check the activity log to see which moderator changed what.

Host Fluxer yourself

Run Fluxer on a server you control and keep your community in your own hands.

Your data stays with you
Messages, files, and accounts are stored on your server, not ours.
Use the apps you already know
Connect to your instance from any web browser or the official Fluxer mobile app. Support in the desktop app arrives in early October 2026.
Federation is on the way
People on different instances will be able to talk to each other. An experimental draft arrives in 2026, and the stable release follows in 2027.
