Ask HN: Are there complimentary front end software for headless CMS?

With directus, strapi, baserow, and other headless cms/api first/database gui products, are there complimentary front end gui style products for non-tech users that will interact with the aforementioned using them as a backend? I recognize that they have their own interfaces, but they are more like an admin interface which still is needed. I understand that you can build the front end using react or vue or another framework, but curious if there is a prebuilt solution.

I recognize that possible solutions might be a cms like drupal, joomla, wordpress etc, but I like the simplicity and blank slate fee of the headless cms and curious if there is an equivalent for custom front end
