Directus is always at the top of self-hosted CMS lists, but one of the reasons I avoid it and other PHP self-hosted headless CMS solutions is due to the difficulties(tech debt) of automating dev environments and CI/CD pipelines across different distros and OSes.

I would have possibly given Directus a spin if it didn't have hard dependencies on the following PHP system extensions: curl, gd, finfo, pdo_mysql and mbstring. Not to go too off topic, but I wish PHP extensions could be installed via Composer and Packagist (similar to how NPM handles native modules).
