RocketChat vs Zulip: What are the differences?

Introduction RocketChat and Zulip are both popular communication platforms that offer real-time messaging and collaboration features. However, there are key differences between the two that set them apart. In this article, we will explore and highlight these differences.

  1. User Interface and Organization: RocketChat has a more traditional chat interface, similar to popular messaging apps like Slack. It organizes conversations into channels and direct messages, making it easy to navigate and manage communication. On the other hand, Zulip offers a unique threaded conversation model that helps in organizing discussions more effectively. Conversations are grouped into topics and subtopics, providing a structured and focused communication experience.

  2. Message Visibility: In RocketChat, messages sent in public channels are visible to all users in the channel, promoting transparency and open communication. However, in Zulip, messages are private by default and users need to be explicitly added to conversations or topic streams to view and participate in discussions. This ensures better privacy and targeted communication within specific groups.

  3. Message Search and History: RocketChat offers a basic search functionality that allows users to search for messages by keywords. It also provides a complete message history within channels and direct messages. In contrast, Zulip provides advanced search capabilities with support for filtering messages based on different criteria such as sender, recipient, topic, and content. Additionally, Zulip also supports message retention policies, allowing organizations to set rules for storing or purging messages over time.

  4. Integration and Extensibility: Both RocketChat and Zulip offer a wide range of integrations with popular third-party services and applications. However, RocketChat has a larger number of out-of-the-box integrations and a more active community for developing custom integrations. Zulip, on the other hand, provides a powerful API and webhooks for building custom integrations, making it highly extensible and adaptable to specific organizational needs.

  5. Multilingual Support: RocketChat supports multilingual interfaces out-of-the-box, allowing users to switch to different languages based on their preferences. It offers a wide range of language options, making it suitable for global teams with diverse language requirements. Although Zulip supports multiple languages for message translation, it currently does not provide a built-in multilingual interface, limiting the user interface to a single language.

  6. Pricing and Deployment Options: RocketChat is an open-source platform that can be self-hosted on-premises or deployed on cloud services. It offers a free version with limited features and paid plans for additional functionality and support. Zulip, on the other hand, provides a cloud-hosted service with a free tier for small teams and paid plans for enterprise-grade collaboration. It does not offer a self-hosting option, making it more suitable for organizations preferring a cloud-based deployment.

In summary, the key differences between RocketChat and Zulip include their user interface and organization style, message visibility, search and history capabilities, integration and extensibility options, multilingual support, and pricing/deployment models. These differences make each platform unique and cater to different communication needs and preferences.

Mattermost sports higher performance, uses Postgres, is a pure server side application not using up too much of system resources on the client side, and gives an overall enterprise grade impression in general.

Updates go smooth without a hassle, everything is organised logically, and the integration with the OS is absolutely stable. Apart from that, the underlying runtimes and code are mature, proven and stable.

The developers are maybe a bit more cautious in regard to introducing new features, but they maintain a stable experience, not breaking the codebase in order to hastily implement bells and whistles, which are not yet ready for production. Documentation and debugging are fantastic, so running this in enterprise production environment is absolutely approved of.

We chose RocketChat over other communications suites like Cliq or Slack mainly because we can self-host it on our own infrastructure. Since we have quite some projects going on which demand that we stay in touch with a lot of different stakeholders, pricing was an issue, too. With RocketChat, we have a huge set of features basically for free, RC offers apps for all major devices and systems and overall, we're very happy with it. The only downside is the limited amount of apps and integrations, but we can make due with what we have available.
