What is Zulip?
Zulip is the only modern team chat app that is designed for both live and asynchronous conversations. Zulip topics create a separate space for each discussion, so different conversations will never get in each other's way. Teams of all sizes rely on Zulip - Fortune 500 companies, open-source projects, startups, and many others. Zulip is 100% open-source enterprise-grade software, self-hosted or in the cloud.
Zulip can transform how your organization communicates:
-
Leaders can prioritize their time and batch-reply to messages, and thus effectively participate in the chat community.
-
More discussions can be moved from meetings and email to chat.
-
Individual contributors can do focused work instead of paging through GIFs making sure they don’t miss anything important.
-
Remote workers can participate in an equal way to people present in person.
-
Employees don’t need to be glued to their keyboard or phone in order to avoid missing out on important conversations.
-Everyone saves a huge amount of wasted time and attention.

The best alternative I've found to Slack after trying Mattermost, Rocket.chat, Riot, Twist. Why? Because:
Also, it's fully cross-platform, can be customized with bots - many already existing or code your own,... I can't recommend enough to give it a try and be surprised like I was!
the custom server hosting is awesome feature which is not common in other alternatives
I really love the way Zulip organizes conversations into named topics. It relieves a lot of stress to know that even after a vacation or some time working on a different project, I can always quickly and easily catch up on everything that's been going on. No other chat application offers such a great conversation model.
Zulip is also open source and offers both self-hosting and cloud hosting, including free hosting plans for open source and academic projects.
Zulip is a group chat app in which messages are threaded by topic, helping you have long-running, organized conversations.
I like Zulip because of its user friendly interface and suggestive tips for group chats.Since ,I started using Zulip it had became very easy to chat professionally and interactively.
Thia is an amazing thread-based free software. It's easy to use and is really helpful when you have numerous messages because of the threaded architecture.
Opensource, Self-Hostable, EMail Threading System, easy customizability + nice and helping maintainers
