Discussion on: Which is the Best Static Site Generator and Why?

Ambiguous question. depends on your skills and the profile of your next products.

• Jekyll - based on ruby, used by Github
• Hugo, Gatsby, Hexo #impressive newcomers. Gatsby requires basic React / GraphQl knowledge.
• Gridsome - the Vue.js cousin of Gatsby, not so mature, the SEO score provided out of the box barely hit 80. A few starters are available. Also based on GraphQl.
• Vuepress - mature product, personally I don't have a good opinion about the support. A few months ago the head of their main branch was broken for one month.
• Pelican - used by Python community, nice tool but .. missing the new features offered by Gatsby, Hugo, Hexo
• Cactus - that's a plant. Joking, never use it
• Roots - never use it.

My personal choice is GatsbyJS for reasons listed below:

• Use React
• Use GraphQL, the REST architecture silent killer
• Impressive implementation of PRPL pattern
• The number of starters for almost any relevant frameworks: Bulma, Tailwind, Motlin, Firebase .. etc
• You get > 90 Lighthouse score, out of the box ..

Happy Coding!
