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 (https://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.
