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

Se poutèt sa yon moun ta ka make Zulip kòm san komès pou "Pwojè Open-source, Rechèch nan yon anviwònman akademik, tankou gwoup rechèch, kolaborasyon kwa-enstitisyon, elatriye, Òganizasyon ki opere pa edikatè endividyèl, tankou yon pwofesè anseye youn oswa plis klas, San bi likratif ki pa gen okenn anplwaye peye oswa Kominote ak òganizasyon pèsonèl". Petèt 3 blòk ta ka apwopriye pou sa?
