What is Fluxer?

Fluxer is an instant messaging and VoIP app built for friends, groups and communities. Clients exist for Windows, macOS, Linux, Android and iOS, with Linux packages for apt, dnf, pacman and Flatpak, and separate stable and canary channels. Bug reports and feature requests go to a feedback site that needs a Fluxer account, since GitHub issues are closed. The interface is offered in 28 languages.

Good fit if

  • Your gaming group or online community wants a Discord replacement with voice channels.
  • You want to host the backend yourself with Docker or Kubernetes.

Look elsewhere if

  • You need a work-focused chat with threads and integrations: Zulip or Mattermost.
  • You want a federated network instead of a single provider: Element.

Before you adopt it

The code is AGPL-3.0, but the artwork in fluxer_static falls under a separate Fluxer artwork license, so the branding assets are proprietary while the application code itself is not sold. The repository was created in January 2026, and one developer writes almost every commit at a very high pace. Docker images and a Helm chart are available.
