Show HN: OpenArcanum – An End-to-End Encrypted Alternative to Discord

https://github.com/hyperkubeorg/openarcanum/
3•SamInTheShell•58m ago
A while back I recall being told it can't be done and won't be "Discord". To that, I have to admit, it's not Discord. It isn't designed in a way to profile it's users and it respects privacy.

There is still much work to do on this project, but it's in open beta with a web client so people can see how it works before committing to a desktop app download. Mobile apps will come later, if there is proven interest in this platform.

I don't care to monitize it. The only thing users will ever see is a non-intrusive "Please donate" badge at most, with the intentions to just keep the maintainer nodes and some official relays running.

There are no accounts. There is no way for me to see the messages. It is a platform that respects the user's privacy and asks nothing of it's user's.

Anyone can run the entire stack in their own hardware, in private, with no limitations on controlling their data.

It is open source (AGPLv3: https://github.com/hyperkubeorg/openarcanum/

And it's live right now for you to check out: https://openarcanum.org

I have a community server running that you may join with this community code (good for 30 days): ``` openarcanum-invite:ChACbbppkdJgXT5JFDYAyCMdEiBcigeLKcJMz5_6LKRhT_sSlYXITfl7Mctu2I5hRPmT1hogy8dDt7EjO6KG5Xz-ufvsCFWE8f_yQtaCFFYE8M83UcEiIXdzczovL3JlbGF5LTAxLm9wZW5hcmNhbnVtLm9yZy93cyIhd3NzOi8vcmVsYXktMDIub3BlbmFyY2FudW0ub3JnL3dzKhhBMnJXa1BYRGRkbHVsVC13V1ZTbDg2OHcyEEhhY2tlciBOZXdzIENyZXc ```
