I'm not associated with WonderCMS and I'm not using it right now. I don't need another blog. But, I used this in the past. I stopped using it because it was just for creating pages at the time. Well, I see now in the features you can turn on "blog mode."
This is a flat file, 5 file, 48kb, 1 step install CMS. And, it looks nice too. You edit things right in place in the frontend.

I'm a fan of when people build something so incredibly small, yet fairly powerful. 👍️
