@danilasch @wordpressdotcom @photomatt Hmmmm…I do not think there are any “perfect” alternatives to WordPress, but the closest is a fork called Classic Press: https://www.classicpress.net/
There is also #WriteFreely (if a blog is what you are looking for): https://write.as
Also #MicroBlog (https://micro.blog) is a good alternative too.
