Zulip is an open source chat and collaborative software created by Jeff Arnold, Waseem Daher, Jessica McKellar, and Tim Abbott in 2012. Today, it is one of the free and open source alternatives to Slack, with over 60,000 commits contributed by over 1000 people.
Here it’s important to differentiate and it’s not so easy to label Zulip as fully trade-free. 1. https://zulip.com/ is NOT trade-free. There are plans that one can subscribe to in the “cloud”: https://zulip.com/plans/#cloud and even in self-hosted version: https://zulip.com/plans/#self-hosted 2. However, there is a “free-community-plan” for certain groups of people (in education or non-profit for example): https://zulip.com/help/self-hosted-billing#free-community-plan
이것이 Zulip을 "오픈 소스 프로젝트, 연구 그룹, 기관 간 협력 등과 같은 학술 환경에서의 연구, 하나 이상의 수업을 가르치는 교수와 같은 개별 교육자가 운영하는 조직, 유급 직원이 없는 비영리 단체 또는 커뮤니티 및 개인 조직"에 대해 무역 자유로 표시할 수 있는 이유입니다. 어쩌면 3블록이 적합할까요?
