you should look at #slcl, a suckless-inspired cloud server software written in C. while it's not quite feature complete yet, it's getting there and it's great
@hamblingreen What is 'feature-complete'? Will it support 'apps' like nextcloud does?
@hamblingreen my nextcloud usage has been dwindling. I use anonymous uploads, password prote-ted (expiring) share, and occasionally news (RSS reader). Of the groupware, mostly caldav is one I rely on so my wife and I can share a calendar.
