Why choose Hibox or Zulip?
Both platforms offer chat, file sharing, mentions, and group/channel features, as well as 1-1 and group video calls, but Zulip has more advanced features such as whiteboarding, recording, and participant permissions. Hibox has better customer support resources, including training and dedicated customer service, while Zulip offers on-premise deployment and SAML/SSO authentication. Ultimately, choosing between Hibox and Zulip will depend on your specific team's needs and priorities.
