Zulip (https://zulip.com/) 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.

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 then catch up on your own time, reading the topics you care about, and skimming or skipping the rest.

Like everything Zulip, this official Zulip mobile app is 100% open-source software: https://github.com/zulip/zulip-mobile . Thank you to the hundreds of contributors who have made Zulip what it is!

Zulip is available as a managed cloud service or a self-hosted solution.

Please send questions, comments, and bug reports to support@zulip.com, or tweet @zulip.

Needs improvement.

Maybe I’m missing it but I’m not seeing the ability to invite to a server in the app.

On the other hand, the server portion was very easy to install - great documentation and the way you organize threads/topics is really cool. I tried several others before settling on Zulip. Keep up the good work.

Ability to upload files is not consistent

Update Sept 2021: why are the media upload options still not working? No one is even asking for a polished design or anything. They’re willing to have a duct-taped together app that lets you view the forums. Still can’t upload a PDF on the app.


Sometimes the buttons to upload files (paperclip, iOS file system etc.) show up. Other times it only shows photo and camera access. When it did show up, it was when the reply to comment button showed up beside the text box, which only intermittently appears even if you have tapped on a comment. If you long press the comment, reply is an option, but the file attachment is only photos. I managed to get a PDF to start uploading, but the keyboard was then pushed off the screen, so I couldn’t hit enter to post it. There may be a related issue to handling landscape to portrait while composing.

Fantastic chat app, best so far

We just started using Zulip at the company because of the threads feature. Running a self-hosted version. This solution is fantastic because it forces users to use topics so keeps messages organized. If working with remote teams who cannot respond in real time this makes a big difference. The iOS app works well too with mobile notifications and easy filtering to see either all or only new messages or only messages in a specific stream (channel) or topic ( thread). If using any paid chat solution where you pay by user, think again. This is open source, we run it on a $10/month instance with a cloud provider.
