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 control and privacy while offering robust features for various types of communities.

Fluxer offers messaging capabilities including DM your friends, chat with groups, or build communities with channels. It features full Markdown support in messages, private DMs and group chats, organized channels for communities, and the ability to share files and preview links. The platform also provides voice and video functionality allowing users to hop in a call with friends or share your screen to work together, with features including joining from multiple devices at once, built-in screen sharing, noise suppression and echo cancellation, and mute, deafen, and camera controls.

The platform includes moderation tools to keep your community running smoothly with roles, permissions, and logs. These include granular roles and permissions, moderation actions and tools, audit logs for transparency, and webhooks and bot support. Fluxer also offers search functionality with a quick switcher to find old messages or jump between communities and channels in seconds, featuring search through message history, filtering by users, dates, and more, quick switcher with keyboard shortcuts, and friend management with blocking capabilities.

Fluxer provides extensive customization options allowing users to add custom emojis, save media for later, and style the app with custom CSS. Users can upload custom emojis and stickers, save images, videos, GIFs, and audio, apply custom CSS themes, and use compact mode and display options. The platform supports self-hosting capabilities where users can run the Fluxer backend on their own hardware and connect with Fluxer apps, featuring fully open source (AGPLv3) code, hosting your own instance, using the desktop client (with mobile coming soon), and switching between multiple instances.

Fluxer is built as a chat platform that answers to you, not investors, being ad-free, open source, community-funded, and never selling your data or nagging you with upgrade pop-ups. The platform serves gaming communities, creators, education groups, hobbyists, and developers with its versatile communication tools.
