A chat app that puts you first

Free and open source chat for friends, groups and communities, with text chat, voice and video calls, screen sharing and self-hosting.

Fluxer desktop interface

Host it yourself (or don't!)

Fluxer works out of the box on our servers. If you'd rather run Fluxer on your own server, you can do that too, 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, code blocks, files, link previews and your community's emoji and stickers.

Jump into voice

Join a voice channel to talk, share your screen or use your camera. You can join from several devices at once, and the app has noise suppression and echo cancellation.

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.

16 Voice regions

We run Fluxer voice servers in each of these regions. Each call uses the region that's closest to the first person who joins it, unless the voice channel is set to a specific region.
