Tumblr is great but I dislike it for same reason I don't like medium, facebook, twitter: I don't own content, database, cannot instantly pack my things and migrate to another hoster. I want to have control over content I host on internets.
Tried webhook CMS as CMS for static website - it has convenient web panel and it is open source, yet it made for installing it on server as SAAS or buying from them as 9$ month what is not acceptable as for that price I can host anywhere using anything. So I switched to Hugo static site generator. Why Hugo? Idk, random. So much of static site generators ~ Now my website generated using Hugo
