It is so inexpensive now to host your own blog. I don’t understand why you would let another platform own and control your content.
Ok. What system WordPress?
Static site generators like Hugo are great. If your blog is static, hosting is much less expensive and easier.
I use wordpress as self-hosted and write.as online
Your own self-hosted one.
If you don't want to. A blog system. On your machine. There is a thing called. A simple HTML, CSS JavaScript blocks. I would really suggest you check out Hugo. Where you write your blogs? In a certain language and it outputs into a simple HTML. Simple files. You don't need a back end server for this kind of a block. Unless you want. Comment section unless you want a fully blown features. And there's No Fear. Other than that. You can still connect. Comments and complicated features using Google, but that would require back end of 3rd party service. But I would suggest. To give Wordpress a try. It's still popular
