Bludit

Bludit is a lightweight, flat-file blogging and content management system that lets you build and manage websites without needing a database.

It’s simple to use, fast, and ideal for blogs, personal sites, and small projects.

I used to use this for my website, but found the support and documentation lacking. Also for what I was using it for, it was probably overkill. I have since moved to Pure Blog, which so minimal and easy to use.
