Try Zulip now See it in use Create organization

Efficient communication

Unlike other chat apps, Zulip lets you read and respond to every message in context, no matter when it was sent. Maintain your focus and catch up on your own time without stress, reading just the topics you care about.
Zulip’s threading model makes it so much easier to manage my team... As a leader, in just a few minutes I can get an overview over what’s going on and see where my attention is needed.
Case study with Gaute Lund, co-founder of iDrift AS

Collaboration at scale

Zulip helps teams of all sizes be more productive together, from a few friends hacking on a new idea, to globally distributed organizations with hundreds of people tackling the world’s hardest problems.
Zulip has the best user experience of all the chat apps I’ve tried... It is the only app that makes hundreds of conversations manageable.
Case study with Tobias Lasser, Technical University of Munich
