The carousel on the main page is very easily understandable, which is great! The whole topics (sub-channels, basically) idea seems interesting as well, though personally the solution itself seems pretty similar to two other great pieces of software out there: <pre><code> - Rocket.Chat https://rocket.chat/ (the Jitsi integration was especially nice).

Both of those also seemed serviceable, decently familiar and usable. I guess even Nextcloud Talk could work if that suits your environment better https://nextcloud.com/talk/ though personally it felt a little more barebones in comparison. Has anyone extensively used any of them and can share what details/differences jumped out at them? Admittedly, I probably missed most of those myself and just saw them as similar, self-hostable chat solutions.
