Our verdict on Fluxer

Fluxer is an open-source chat platform for friends, groups, and online communities. It brings direct and group conversations together with organized community channels, plus voice, video, and screen sharing. Messages support Markdown and code blocks, and members can share files and link previews. Its mix of social chat and community administration makes it a fit for small groups that want more structure than a group conversation, especially operators interested in running their own server.

The feature set covers much of a community's daily communication and management: roles and permissions, timeouts, kicks, bans, and a community activity log sit alongside chat and calls. Self-hosting lets an operator run Fluxer on a server they control; those who prefer not to manage a server can use the cloud deployment. The service spans web, Windows, macOS, Linux, iOS, and Android, though mobile apps are in public testing. Email and documentation are the listed support channels, and GDPR is the stated compliance item.

Fluxer has an ongoing Free tier and an optional Plutonium subscription. According to the published plan details, Plutonium raises community and message limits, allows custom emoji and stickers across communities, and increases video-call and screen-share quality. Those upgrades matter most to communities nearing free-tier limits or prioritizing richer media. The published plan details repeat the Plutonium entry, so tier distinctions are not especially clear. Fluxer is a sensible fit for small communities prioritizing open-source chat and self-hosting; groups that depend on listed integrations or require production-ready mobile apps should consider alternatives.
