Why choose Rocket.Chat or Zulip?

Rocket.Chat and Zulip are two open-source communication platforms with high G2 scores of 4.1/5 and 4.2/5, respectively. While Rocket.Chat targets a global tech audience, Zulip focuses on open-source tech users.

Rocket.Chat offers a free version, custom domain name, roles management, and workspace/user activity monitoring, while Zulip offers a free trial, participant permissions, branding removal, and up to 5GB of storage. Both platforms offer chat, file sharing, groups/channels, mentions, and emojis, but Zulip lacks some features like voice messages, threads, and AI. Rocket.Chat requires integrations for video calls, while Zulip offers group video calls, whiteboarding, screen sharing, audio calls, and recording. Both platforms offer mobile, web, and desktop apps, integrations/APIs, and two-factor authentication. However, Rocket.Chat supports on-premise deployment, SAML/SSO authentication, and end-to-end encryption, which are not available in Zulip.
