Zulip, the free/open source team chat project has released their 1.8 version. We’ve talked about Zulip and other Slack alternatives on SourceContribute before. What makes Zulip special, aside from being free/open source, is that it has better threads and threading than Slack.
Threads are ways of creating a continuous discussion around a particular topic. In Slack, they’re very rarely used, everyone usually just @-replies. However, Zulip’s UX for threads makes them so useful that you’ll be using them far more often.
Not only that! Zulip also has video calls integrated with Jitsi Meet.
And a new feature I really like is being able to @-reply to a group of people; you can do things like @teamA or @marketing to make it easier and faster to notify the right group of people about something.
Zulip was posted on ProductHunt in December. Other free/open source projects should be posting their releases on ProductHunt too; there are far too many proprietary projects on that site.
Zulip has a new darker theme, keeping in tune with the hacker/coder idea of what makes a great desktop environment.
I have a feeling that Zulip is in the right spot, along with Riot.im, to really give Slack a run for its money now. Just check out the number of integrations that Zulip has.
