Notebrew is an open-source static site CMS and blogging platform for Windows, macOS and Linux.
Notebrew is a static site generator with a Content Management System (CMS) built-in. It can be self-hosted or ran as a desktop program.
Some themes are available.
If you are self-hosting, Notebrew itself is a production-ready web server that automatically handles HTTPS so you don't need to fiddle with a separate web server like Nginx or Apache.
