About Zulip
Zulip is an open source team chat app that organizes conversations into topic threads. It is built for distributed and asynchronous teams that need to follow many discussions at once.
What it does
Each conversation in Zulip has a topic, and replies stay inside that thread. The inbox shows which conversations have unread messages, so you can focus on one thread at a time without losing your place in others. Over time the threads build a searchable record of decisions and knowledge, which many teams use in place of long chat logs.
Key features
- Topic threads that keep each conversation in context
- Inbox view of unread conversations
- Reply inside the right thread
- Self-host the open source server or use the cloud
- Tools to move over from Slack and Teams
Who it's for
Distributed and open source teams, and organizations that work across time zones. Teams that find fast chat hard to follow will find the topic model helpful.
Pricing and good to know
The server is open source under the Apache 2.0 license and can be self-hosted for full control of your data. A cloud version with paid plans is also offered, and you can move between the two. Teams used to a single running chat may need a short period to get used to starting topics.
Highlights
- Keep each discussion in its own topic
- See unread conversations in one inbox
- Reply inside the thread where a topic started
- Self-host the server for full data control
- Import from Slack, Teams and other tools
