What language / stack do you know or use the most? go to staticgen.com and filter by your preferences. I used sculpin as it's really simple and for static landing pages you don't have to mess with many things. I tried gatsby, and to include an script on the head (the gtm js) you have to use a plugin or escape the script and include on helmet. I also used docfx indirectly to make automatic documentation pages for dotnet apis and it worked flawlessly, however I didn't have to do anything special on it, which is where the problems start to appear.
