Fluxer is an open-source, independent instant messaging and VoIP platform designed specifically for friends, groups, and communities. The platform provides a comprehensive communication solution that prioritizes user privacy and community building without intrusive advertising or data selling.

The platform offers robust messaging capabilities including direct messages, group chats, and organized channels for communities with full Markdown support. Voice and video features allow users to join calls from multiple devices simultaneously with built-in screen sharing, noise suppression, and echo cancellation. Moderation tools provide granular roles, permissions, audit logs, and webhook support for community management.

Fluxer operates as an open-source platform licensed under AGPLv3, allowing users to self-host their own instances while connecting with official desktop and mobile applications. The platform emphasizes transparency and community funding rather than investor-driven development models.

Users benefit from an ad-free experience with features like custom emojis, CSS theming, message search with filtering options, and quick navigation between communities. The platform supports file sharing, link previews, and media saving capabilities for comprehensive communication needs.

The product targets gaming communities, creators, educational groups, hobbyists, and developers seeking privacy-focused communication tools. Future developments include federation capabilities, end-to-end encryption, slash commands, threads, forums, and creator monetization features.
