👀 Some words about Chatto, my BIG project. It's a group chat app that - is incredibly easy to self-host - has very modest hardware requirements - scales really well - apache-2.0 license - hosted platform launching in 2026 Looking forward to writing much more about this soon. Let's do this. 🚀

interested! currently using zulip and happy with it after using slack (stupid expensive), mattermost (bloated with useless features and ux is off), campfire (halfbaked), and rocketchat (bad UX). two downsides of zulip: mobile app is still a baby, and push notifications are paid after 10 users :(

Zulip is good! But from my experience its paradigm is too far removed from what people are used to from the Slacks and the Discords and the whatnots. It was particularly hard to make a case for it in a business context.

I want to build something that works both for business as well as community/gaming/casual use cases. Gunning for the "typical" UX as a base and then try some things on top of that (particularly around threading, room types and the likes.)
