Has anyone any experience with #opensource #slack alternatives, self hosted or otherwise? I've been reading up, but it would be useful to hear from somebody that has practical experience.
@lgatto @keyboardpipette we're using Mattermost, self-hosted on our server. It works very good, transition (usage) from slack was smooth. main reasons for it: was already connected to a mattermost workspace on another server and didn't want to have yet another client/app
@jorainer @keyboardpipette thank you, good to know. Is is managed by the institute's admins?
@lgatto @keyboardpipette yes, but they did not complain that it's too complicated to setup or manage - and seems also secure since our admins are supercareful
