Systatic is a Modern Static Site Generator built in PHP. It's faster and simpler than traditional static site generators.
Apart from using PHP to generate your site, you can use whatever tech stack you want, Vue, React, whatever. We don't dictate what you need.
Because Systatic generates HTML files, you can host your site anywhere you can put HTML files: Netlify, Github Pages, Amazon S3.
You can put your data where ever you want. You could have it in Markdown files, WordPress or even a headless CMS and it will all work and feel the same.
