Dokku is nice and I used it for a while but recently I've been using CapRover [0] and been pretty happy with it. I only use it on 1 host but it supports multiple. It also has 1-click installs for the usual suspects (drupal/wordpress/etc) and things like spinning up a DB is easy. You can also define a docker file in your repo that you instruct it to build and use. HTTPS is a button click and it automatically sets up virtual hosts for you `<your app name>.<base url you configured>`. It's great for quick prototyping and to get a personal project online.
