What Is Fluxer?

Fluxer is a free, open-source instant messaging and VoIP chat app designed for friends, groups, and communities. You can use it in a web browser at web.fluxer.app, but the page requires JavaScript to be enabled — without it, the app will not load.

What Fluxer Offers

Based on the project's own description, Fluxer combines two core functions in one app:

• Instant messaging — text-based chat for staying in touch with friends, groups, and communities.
• VoIP chat — voice communication over the internet, built into the same application.

It is positioned for small and mid-sized social settings: friend circles, group chats, and community spaces, rather than enterprise or business communications.

Key Characteristics

What to Expect When You Visit

The web app is a JavaScript-rendered application. If you open web.fluxer.app and see only a message stating that JavaScript is required, that means your browser has scripting disabled or a script blocker is preventing the app from loading. Enabling JavaScript for the site (or allowing it in your content blocker) is the prerequisite for using Fluxer in the browser.

Who Fluxer Is For

Fluxer fits you if you want a no-cost, open-source alternative for group text and voice chat and you are comfortable using a browser-based app. Because the project is open source, it may also interest people who prefer transparent, community-driven software over closed platforms. If you need a native desktop or mobile client, or features beyond messaging and voice chat, the available information does not confirm those capabilities — check the project's own pages before committing.
