Hi,
after several trials and testing, my final thoughts are the following:
- Grav it is the ideal successor of Wordpress. It is faster and provides multilingual support and a lot of plugin. Unfortunately, the plugin that provides static Web site generation does not work
- Lektor it is very simple to use. It provides multilingual support and static Web site generation. However, it is too spartan and in my opinion requires further improvement
- Publii it is the most promising (app written in javascript-electron). It works entirely locally, easy to install, easy to use and provides static Web site generation with deploy to gitlab. It lacks of multilingual support (expected next year) and it has few themes.
- Netlify it works online directly on gitlab. It supports both hugo and gatsby framework and static Web site generation. I tried a theme for the first that provide multilingual, but it is not very user friendly.
- Jekyll Now it is a faster way to use Jekyll as static Web site generation directly into gitlab. Unfortunately, it is not simple to use multilingual support and the “GUI” is not user friendly compared to the others.
In conclusion, my suggestion is to use Publii a new way to static Web site generation.
