Starter-Kit-V4-Eleventy VS Directus

Sounds like you're talking about volunteering :), just make sure they're fine with having their website being built with code, since they won't be able to edit it as easily, if they need a Blog or something like that you can look at this repo

I don't know, it's something I've wanted many times.

Recently I discovered https://directus.io/ which comes pretty close and it's open source.

I using Directus CMS on several projects with pretty complicated flows, api extensions etc. probably there will be some work if you move. I liked Directus is because it's standard SQL I can always move my DB and documents to another solution. I don't use their hosted solution but they have an unlimited offering for $100 / month.

Have you looked at Directus? I’m not sure exactly what your needs are (sorry if I’ve misunderstood). I used it for my most recent project as the backend for data entry/queries/administration. It supports MySQL, but admins don’t need to know anything about SQL to do complex queries/filters/CSV exports from the Directus UI.
