Fluxer

About

Fluxer is free and open source chat for friends, groups and communities. You can 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. Fluxer is available in 34 languages.

Fluxer includes voice and video calls and screen sharing. Join a voice channel to talk, share your screen, or use your camera, and join from several devices at once. The app has noise suppression and echo cancellation. Fluxer runs voice servers in 16 regions, and each call uses the region closest to the first person who joins, unless the voice channel is set to a specific region.

Fluxer works out of the box on its own servers, or you can self-host it on your own server. Community owners can give people roles with specific permissions, time out, kick or ban members, and check an activity log to see which moderator changed what.
