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.
Although the service is freemium, it does not require a subscription for most features, and the platform promises never to sell user data and never to use it to train generative artificial intelligence.
Fluxer is offering self-hosting, and federation is on its roadmap.
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.
In March 2026, Fluxer had reached 125,000 users on its primary server. When Discord's IPO plans leaked, a viral Bluesky post led to massive user influx and server overload, changing the scale of the project drastically.
