Zulip review

Zulip is team chat built around conversations with topics. Start a message with a brief topic, then keep replies attached to that conversation instead of letting them disappear into a fast-moving channel. An unread inbox helps people catch up, and focused-conversation views let them work through one discussion at a time while other chats continue.

Teams can use Zulip Cloud or self-host its open-source software. The product information says teams can move between the two, and Zulip supports migration from Slack and Microsoft Teams. That gives organizations a choice between managed hosting and running the service themselves.

The trade-off is that topics are part of how Zulip works, not an optional filing system. Some Reddit commenters say deciding on a topic before posting feels unfamiliar or slows them down. Zulip is therefore a better fit for teams willing to organize chat deliberately than for people who want every message to land in a simple, flowing conversation.

Zulip’s main advantage is that it makes busy chat easier to revisit. Topic-based conversations and threaded replies keep separate discussions from colliding, while the unread inbox gives people a way to catch up without reading every message in order. That structure suits asynchronous teams and communities where people join conversations at different times.

Self-hosting is another meaningful option for organizations that want to manage their own server. The pricing page lists all Zulip features in its self-hosted plans, with paid plans adding services such as mobile notifications and, on Business, support and SSO. Cloud is available for teams that would rather not operate the infrastructure themselves.

The pricing page lists a free Cloud plan with 10,000 messages of search history, 5 GB total file storage, hundreds of integrations and guest accounts. Standard costs $8 per user monthly, or $6.67 with annual billing, and adds unlimited search history, 5 GB of storage per user and priority commercial support. For eligible communities and organizations, the free self-hosted plan includes all Zulip features. Those choices make it possible to start without a subscription and pay for more history, controls or service as needs change.

Zulip’s structure asks users to make a choice before they post: what is this conversation about? Some commenters on Reddit say that requirement feels unintuitive, especially when they are new to a community or unsure how to categorize a question. Others say the interface is more complicated than Slack. That learning cost matters when a switch depends on casual members adopting another app; one commenter described familiarity with Slack or Discord as a real barrier.

The free Cloud plan is capped at 10,000 messages of search history and 5 GB of total file storage. Standard removes the search-history cap, but costs $8 per user monthly or $6.67 annually. Plus starts at $12 monthly or $10 annually and has a 10-user minimum. On self-hosting, Business costs $8 per user monthly or $6.67 annually, with a 25-user minimum; Enterprise pricing is not published.

The free self-hosted plan also has notification limits: unlimited mobile notifications for eligible communities, but notifications for up to 10 users at other organizations. So self-hosting does not automatically mean every hosted service is unlimited or free.

Zulip Cloud starts free, but search history is capped at 10,000 messages and storage at 5 GB total. Standard costs $8 per user monthly or $6.67 annually, with unlimited search history and 5 GB storage per user. Plus rises to $12 monthly or $10 annually and requires at least 10 users; it adds SAML SSO and SCIM sync. That minimum makes Plus at least $120 monthly, or $100 monthly on annual billing.

Self-hosted Basic costs $3.50 per user monthly; the pricing page does not list an annual rate. Business is $8 monthly or $6.67 annually, with a 25-user minimum and SSO. Free self-hosting is limited to eligible communities and organizations. Enterprise pricing is custom. The page lists $20/month off Basic and Business for the first year, but the published pricing details don't clarify how that offer is applied. Compliance customization and support for Basic and Business are billed hourly. Annual rates are lower for Standard, Plus, and Business; Basic is monthly only.

Zulip says teams can move from Slack or Teams and can switch between its cloud service and self-hosting. That gives you options, but the published materials don't specify migration steps, what data transfers, or how long a move takes. They also don't describe data export formats or whether exports include files, topics, and reply history. Confirm those details before treating migration or exit as straightforward.

Self-hosting the open-source software is an option for organizations that want data sovereignty, but it means managing their own server. The pricing page lists support for some paid self-hosted plans; it doesn't detail migration assistance. The product's topic-based structure may suit teams that want async conversations, while teams seeking casual, topic-free chat may find it a poor fit. We don't have Reddit posts or comments in the published published material, so we can't responsibly attribute common reasons for leaving to Reddit users.
