I'm doing my best to migrate my databases off DigitalOcean's managed platform. It has served me well over the last 4 or 5 years with no regrets.
I created a tool, I'm calling PG Hub, which makes it much easier to create a new user + database from a website and even returns a formatted DATABASE_URL.
Today, I shipped a dozen features for it, including the first backup, restore, and copy-to-another-database tool that I don't hate.
