    About Fluxer Platform AB

    Fluxer Platform AB is a Swedish technology company that develops and operates Fluxer, an open-source (AGPLv3) instant messaging and VoIP platform. Designed as a user-centric alternative to proprietary chat services, Fluxer emphasizes community moderation without corporate overreach and allows users to self-host their own backends while staying connected to the official ecosystem. The platform is currently in a beta phase, supported by a community-funded model known as 'Plutonium.' This premium tier offers enhanced features such as verified community status, direct team access, and vanity URLs. Fluxer is built with a focus on customizability, including support for custom CSS, and aims to provide a secure environment for friends, groups, and creators to interact through text, voice, and video.
