> A typical web app requires a database, storage or caching backend, which can get complicated to run with Heroku.

Plainly wrong. Easiest thing ever to spin a pg instance for free and have it immediately available for your app to use.

Better Heroku? Does it let you use a pipeline of dev, staging and prod? Does it auto create new copies of your app (db and other services included!) every time you issue a pull request? Does it destroy those apps/services when you merge to master? Does it let you push to prod with one button? Integrated logs viewable on the web ui? Hell, integrated bash to a copy of your app in the web ui? Oh I forgot testing... webhooks... access control for other devs...

Better Heroku. Pathetic
