The category is “Platform as a Service”

Alternative to Fly or Heroku

Here is my source code Run it on the cloud for me I do not care how

In this case it looks like they also bundle together a bunch of the other services you would need to get code onto the platform, monitor it once it’s there and so on

Oh I see, so they manage the server hosting and application server configuration, optimization and all that jazz. Almost like one step away from managed hosting. Makes sense now, thankyou!
