My go-to for creating a static website to be managed by non-tech people is Svelte + some markdown renderer. I put all the info into Markdown files so it can be easily changed, kind of like Jekyll.
It’s the typical “developer’s developer” solution. Fun for the dev to set up and write an article about how they built it on Dev.to, but with zero thought put towards the marketing functionality or flexible content production that any end user will need.
Developers don’t understand that their role in the process of creating a marketing site is the least important one. The marketing functionality (advanced SEO, newsletter sign up, form collection, landing page generation, dynamic header banners etc) and multi-author content production is all that matters. Otherwise nobody will ever be visiting the site.
Content is king. Not “developer pleasure is King.” Hence why Wordpress runs most of the internet.
More and more non-tech people are happy to be introduced to github. It's just an 'article' dir where you upload your markdown file, then click on 3 green buttons to create a PR.
They're happy to discover the integrated discussion system, issues, kanban, etc.
Of course, tailor it to your audience. Some people cannot read English and will be frightened by the interface.
