Problem
Most chat and community platforms are run by centralized companies that control user data, restrict access, and can change or remove features at any time. Users and community operators have limited control over their own communications infrastructure and cannot be certain how their data is being used behind the scenes.
Solution
Fluxer provides a community platform that combines text, voice, and video channels with granular role-based permissions, enabling organized group communication with full self-hosting capabilities. The platform is open source under AGPLv3, allowing anyone to run their own instance on their own server, where all messages, files, and accounts stay on their infrastructure. Fluxer also offers a hosted option for users who prefer not to manage their own servers. Messages support Markdown, code blocks, files, link previews, and custom emoji and stickers, while voice channels offer screen sharing, camera, noise suppression, and echo cancellation. Self-hosted instances do not phone home or depend on a central sign-in system, and upcoming federation will allow users on different instances to communicate with each other.
Target Audience
Primary users are community operators and organizations that want full control over their communication data and infrastructure, including privacy-conscious groups, businesses, and technical communities seeking an alternative to centralized chat platforms.
