Open-source Discord-like instant messaging & VoIP platform
Fluxer is an independent, open-source instant messaging and VoIP platform designed as a community-first alternative to Discord. Built with privacy as a core principle, Fluxer offers no ads, never sells user data, and is fully funded by the community rather than investors. The platform is completely open-source under the AGPLv3 license, allowing users to self-host their own instances while using official Fluxer clients. Currently in public beta, Fluxer has been featured on Product Hunt and offers a compelling combination of familiar chat functionality with transparency and user ownership.
