Direct Git deployment (no intermediate Git hosting)
I've been using a lot of other hosts these days (Pantheon, Fortrabbit, etc.) that provide a git endpoint – pushing a commit will then deploy the code and run composer install.
This removes the need for an intermediary like Github, Gitlab, Beanstalk etc. and makes everything a lot more streamlined.
Not having this is probably the #1 reason I don't use Cloudways more.
