Fluxer

Open-source Discord-like instant messaging & VoIP platform

2026-01-03

Product Introduction

  1. Definition: Fluxer is an open-source instant messaging and VoIP platform (AGPLv3 licensed) designed for secure, community-driven communication. It operates as a self-hostable, decentralized chat application supporting text, voice, video, and file sharing.
  2. Core Value Proposition: Fluxer exists to provide an ad-free, privacy-focused communication tool free from investor control. It prioritizes user sovereignty, data ownership, and community sustainability through transparent funding models and open development.

Main Features

  1. Messaging & Channels:
    • Supports Markdown formatting, file sharing (images, videos, audio), and link previews.
    • Organizes conversations via private DMs, group chats, and topic-based channels.
    • Uses WebSocket protocols for real-time updates and REST APIs for message history.
  2. Voice & Video VoIP:
    • Enables multi-device calling with noise suppression, echo cancellation, and screen sharing.
    • Built on WebRTC technology for browser-based access; desktop clients use optimized native bridges.
    • Features granular controls: mute, deafen, camera toggling, and per-user volume adjustment.
  3. Moderation & Administration:
    • Role-based permissions (granular controls for channels/messages) and audit logs.
    • Supports bot integration via webhooks and automated moderation actions (e.g., keyword filtering).
    • Includes message search with filters (user, date, channel) and keyboard-driven quick-switcher.
  4. Customization & Self-Hosting:
    • Allows custom CSS theming, emoji/sticker uploads, and media galleries.
    • Self-hostable backend (Node.js/PostgreSQL) with official desktop clients; mobile in development.
    • Cross-instance compatibility: users can connect to multiple independent Fluxer servers.

Problems Solved

  1. Pain Point: Eliminates data monetization and intrusive ads plaguing mainstream platforms (e.g., Discord, Slack).
  2. Target Audience:
    • Privacy-conscious communities (activists, educators).
    • Gaming groups and creators needing customizable, high-fidelity voice chat.
    • Developers and sysadmins seeking self-hosted Slack/Teams alternatives.
  3. Use Cases:
    • Community moderation: Granular roles automate governance for large servers.
    • Secure team collaboration: Self-hosting ensures sensitive data never leaves internal infrastructure.
    • Creator monetization: Future tools (e.g., tip jars, premium content) enable revenue without platform fees.

Unique Advantages

  1. Differentiation:
    • No venture capital influence – funded via donations, Plutonium subscriptions ($4.99/month), and partnerships.
    • Superior customization vs. competitors: full CSS control, custom emojis, and open API.
    • Upcoming federation allows opt-in cross-server communication, unlike walled gardens like Discord.
  2. Key Innovation:
    • Plutonium tier rewards early adopters with lifetime perks (e.g., Visionary pass) and funds development.
    • Transparent roadmap: Publicly tracks features like E2EE messaging, slash commands, and RSS feeds.
