#4 Product of the DayDecember 28, 2017

Zulip is a powerful, open source group chat application that combines the immediacy of real-time chat with the productivity benefits of threaded conversations.

  • Pros: 

    The fully threaded model of Zulip allows you to follow conversations that you care about and ignore the ones you don't.


    Nothing I can think about. It's insanely great :)

    Zulip is built by keeping productivity in mind. Each conversation in Zulip has a topic. This allows you to take part in more than one conversation at the same time. This also make catching up on conversations efficient as compared to cSlack, Mattermost etc where you have to scroll through hundreds or thousands of messages to figure out what is going on. Zulip is the most active open source chat application in GitHub and has 350+ contributors from all across the world.

    Open source, chat based on topic, lots of integrations


    Sorry, can't able to find.

    Zulip chat is awesome.

    It's best alternative for Slack, Mattermost, Hipchat and other group chat apps.

    It has amazing search feature with lots of operators.

@miftakhul_farikhin The first commit of Zulip was made in 2012[1]. Slack was launched to public in 2013. Zulip is a fully threaded chat application which is quite different from Slack or Slack clones like Mattermost/Rocket Chat. Zulip's threaded model allows you to have more than one conversations at the same time which is a pain in Slack/Slack clones. Also each conversation in Zulip has a topic which allows you to catch up on past conversations easily without having to scroll through hundreds or thousands of messages. Come hang around in chat.zulip.org if you want to experience Zulip and see for yourselves how it compares to Slack clones :) [1]https://github.com/zulip/zulip/c...

$8 a month is more expensive than Slack and less features?

@androidlove You have the option to host for free in your own server. Also please note that Slack has $6.67 plan with less features and $12.50 plan with all the features. If you choose not to host in your own server and use Zulip cloud, Zulip only have one plan of $8 per month and you don't have to pay any extra bucks for features like 99.99% "guaranteed" uptime :) Also curious to know which features you use are missing in Zulip which Slack has?
