Fluxer

Fluxer is a free, open-source instant messaging and VoIP platform designed for friends, groups, and communities that need reliable real-time communication. It provides text chat, voice, and potentially video communication in a unified interface, with a focus on privacy, transparency, and user control. As an open-source project, Fluxer allows individuals and organizations to inspect the code, contribute improvements, or self-host the service according to their needs.

Fluxer supports 1:1 and group messaging with features such as message history, read status, and media sharing for images, files, and links. VoIP capabilities enable high-quality voice calls, group calls, and community voice channels, making it suitable for both casual and organized discussions. Being open source, Fluxer can be extended or integrated with other tools, and it typically offers cross-platform availability so users can stay connected from desktop or mobile devices. The platform is designed to be lightweight and responsive, offering a streamlined alternative to heavier, commercial communication suites.
