What is the best static site generator?

[Madagaskar]

I decided to make a notion on the best static site generator available in the web.
What providers can you suggest me to try?
Found Flatsite.com but still don't know if you can trust them.
Do you know anything about them?
Alternatives for comparison?

A static site generator is a tool that generates a full static HTML website based on raw data and a set of templates. Because these HTML pages are pre-built, they can load very quickly in users' browsers.

You may do it manual. it is better to get priority for root pages.
