What is Fluxer?

Fluxer is a free, open-source instant messaging and VoIP platform designed for friends, groups, and communities. It combines real-time text chat with voice and video calling, all while giving users control over their data.

Who it's for

• Privacy-conscious users who want to self-host their communication infrastructure and avoid centralized data collection.

• Friends and small teams who need a reliable mix of direct messaging, group chats, and screen-sharing for collaboration.

Key features

Messaging and channels

Fluxer supports direct messages, group chats, and community channels. You can search through old messages and jump between conversations instantly, making it easy to stay organized across multiple communities.

Voice and video calls

Hop into voice calls with friends or share your screen for collaborative work. The VoIP functionality is built directly into the platform, so you don't need third-party tools for real-time communication.

Customization and moderation

Add custom emojis, save media for later, and style the app with custom CSS. Community management is handled through roles, permissions, and logs, giving you fine-grained control over who can do what.

Self-hosting and open development

Run the Fluxer backend on your own hardware and connect using the official apps. The entire project is developed in the open, with public roadmaps, bug tracking, and a security bug bounty program that rewards responsible disclosures.
