Fluxer is an open-source, independent instant messaging and VoIP platform built for friends, groups, and communities. It offers messaging, voice and video calls, moderation tools, and customization options.
Fluxer is a free and open source chat app designed for friends, groups, and communities. As an independent instant messaging and VoIP platform, it puts user privacy and control first. Built in Sweden, Fluxer provides all the basics expected from a modern communication tool plus unique features like self-hosting and customization. The primary value proposition is giving communities full ownership of their communication infrastructure without relying on corporate services. Whether you are a small group of friends or a large community, Fluxer offers a scalable solution that respects your data and allows you to tailor the experience to your needs. This open source chat app is available for desktop and browser, with mobile support coming soon.
The core problem Fluxer solves is the lack of control and privacy in mainstream proprietary chat applications. Many popular platforms collect user data, impose restrictive terms, or lock users into ecosystems that limit customization. Communities lose ownership of their communication channels and are subject to changing policies and algorithms. Fluxer addresses this by being fully open source and self-hostable. Users can run the entire backend on their own hardware, ensuring that their data remains under their control. This matters to privacy-conscious individuals, community leaders, and organizations that need to comply with data governance requirements. By offering a transparent, community-driven development model, Fluxer eliminates the risk of vendor lock-in and gives users the freedom to modify and extend the platform as they see fit.
The first major feature group is messaging. Fluxer supports full Markdown in messages, enabling rich text formatting for clear and expressive communication. Private direct messages and group chats provide one-on-one and small group conversations, while organized channels structure larger communities into dedicated topics. Users can share files and preview links without leaving the conversation. This feature set works by allowing community admins to create hierarchical channel structures, ensuring that discussions stay organized and easily navigable. The utility is obvious: instead of scrolling through a chaotic feed, members can find relevant conversations in dedicated channels. Markdown support enhances readability, especially in technical communities that share code snippets or formatted documents. The combination of DMs, group chats, and channels makes Fluxer suitable for both casual and formal communication contexts.
The second major feature group is voice and video calling. Fluxer allows users to join calls from multiple devices at once, offering flexibility for those who switch between desktop and mobile. Built-in screen sharing facilitates collaboration on projects, presentations, or troubleshooting. To ensure audio quality, the platform includes noise suppression and echo cancellation. Users have mute, deafen, and camera controls for complete management of their participation. These features work by leveraging sixteen voice regions across six continents, so calls connect through the nearest server for low latency. This global network ensures that users anywhere can enjoy real-time communication without lag. The usefulness is evident in scenarios like remote team meetings, gaming sessions where clear voice is essential, or virtual events with many participants. Screen sharing further transforms Fluxer into a collaborative workspace.
