Fluxer is a free and open source instant messaging app and VoIP social media platform. It was created independently by Swedish student Hampus Kraft and released to the public in early January 2026. It is seen widely as an alternative to Discord, gaining popularity following its age verification policy changes.

It was created independently by Swedish student Hampus Kraft and released to the public in early January 2026.1 It is seen widely as an alternative to Discord, gaining popularity following its age verification policy changes.23 Although the service is freemium, it does not require a subscription for most features, and the platform promises not to sell user data or use it for generative artificial intelligence.45

Fluxer has self-hosting, and federation is on its roadmap.26

History

The app was released in early January 2026 in hopes of competing with Discord. By late February of the same year, there was a sharp rise in new accounts, following Discord's announcement of a new age verification policy.7

In March 2026, Fluxer has reached 125,000 users on its primary server.8 After it quickly gained popularity in February 2026, the software experienced major outages due to massive user influx, server overload and migration of the backend infrastructure.9

Plutonium

The Plutonium Subscription serves as a paid premium plan. It offers a wider range of tools such as high upload size of files and raised limits, however only applies to the official Fluxer instance,10 and third-party hosts aren't affected and can set their own limits and tiers.3

Server operators may optionally buy the Operator Pass, getting additional support, however it isn't necessary to operate a Fluxer server.10
