What is Zulip?

Zulip is an open-source group chat application. It's designed for teams of any size - as small as 2 people and as large as hundreds of thousands. It allows users to organize discussions around a shared topic, like a product, company, or project.
Zulip was created because alternatives like Slack became too expensive for most organizations and mediums of communication like email are too complicated when you have a team of people with different preferences. Zulip allows you to create your own private workspace that's completely customizable and has features like file sharing and bots.
