Well, primo is an SSG, but some advantages over other SSGs: no setup for Tailwind/PostCSS, no setup for js modules/libraries, reusable components, coding from the browser, encapsulated component styles, developing components in isolation, wiring up components to fields in seconds, and a CMS your mom can use. More to come by version 1.

If I understood it correctly, the devs create the components and the end user (editorial people) can edit the content in a nice editor. Like this: https://imgur.com/7W9zcW9
