Why choose Slack or Hibox?
Both Slack and Hibox offer chat, file sharing, mentions, and voice messages, but Slack has more features such as polls, threads, and breakout rooms. Hibox offers task management and a calendar for tasks, while Slack offers a calendar for all events. Both have mobile, web, and desktop apps, integration with APIs, and end-to-end encryption, but Slack has more security features such as two-factor authentication and SAML/SSO authentication. Overall, Slack offers more features and add-ons but at a higher cost, while Hibox offers a more affordable option with task management and a calendar for tasks.
