Zulip
Open-source team chat that organizes channels by topic
Which one is for you
Pick Openfire if
- Fits if you want to run your own chat server and control the data
- Works for sysadmins already comfortable with Java and XMPP
Look elsewhere if
- Not for you if you do not want to maintain a server, since there is no hosted version
- Watch out: from version 4.7.0 on, no Java runtime is bundled
- Skip it if you need paid support, as only the community forum and issue tracker are listed
- Watch out: the Spark desktop client was last updated in March 2023
- Too light for end users on its own, since they need a separate chat client
Pick Zulip if
- Fits if your team is spread across time zones and reads chat hours after it happened
- Works for open-source projects and research groups, which can apply for a free Standard plan
Look elsewhere if
- Skip it if you want voice and video calls built in, as they depend on an outside provider
- Tight if you stay on Cloud Free and need to search old messages, since it covers the latest 10,000 and 5 GB in all
- Not for you if you need SAML on Cloud with under 10 people, because Plus has a 10-user minimum
- Watch out: free self-hosting sends phone push notifications to 10 users only, unless you qualify as a community
- Pricey if you self-host with single sign-on for a small team, as Business has a 25-user minimum
How we grade them
| 2.2GPAOpenfireFair | 2.8GPAZulipGood | |
|---|---|---|
| Value for money | CFree under the Apache License, but only useful if you host it, which needs a server. | BSelf-hosted Basic is $3.50 a user a month, in the cheapest quarter of team chat, and Cloud Standard is $6.67 billed annually, under the $7 middle. Open-source projects, research groups and small nonprofits can apply for Standard free, and schools pay from 67 cents a user. |
| Free plan and trial | AFree outright, with no paid edition and no cap. | BSelf-hosting is free with every feature. Two catches: mobile push notifications stop at 10 users unless you register as an eligible community, and Cloud Free searches only the latest 10,000 messages with 5 GB in total. |
| Features | CXMPP server, plugins and admin console. The matching Spark desktop client was last updated in March 2023. | CTopics you can rename, move and mark resolved, code highlighting, LaTeX, polls, reminders, 130-plus native integrations and a terminal app. The gap is calls. Zulip builds none, handing voice and video to Zoom, Jitsi or BigBlueButton. |
| Ease of use | DNo rating on record. You install a server, supply a Java runtime and maintain it. | CNo App Store rating on record, and the topic model is a habit to learn: every message needs a topic, and a team that doesn't keep them tidy ends up worse off than with plain channels. Self-hosting, if you go that way, is a server to run as well. |
| Platforms and integrations | CRuns on Windows, Mac and Linux servers, with plugins. Clients are separate, and no hosted version exists. | AWeb, Mac, Windows, Linux, iPhone, Android and a terminal app. More than 130 native integrations with thousands more through Zapier and IFTTT, a REST API, custom webhooks, and bridges that pass messages to and from Slack, Microsoft Teams and Matrix. |

Zulip
- Zulip Cloud Free searches only the most recent 10,000 messages and has 5 GB of file storage for the whole organization.

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
