This is ridiculous (as usual) - what are the alternatives folks are using? Or are there really no options like "git push heroku master" where everything just works (or at least, used to work magically).
I've tried all four, and Render is the closest experience to Heroku. It still isn't as easy to use as Heroku, but it is close.
Recently pivoted front end to vercel and it has been amazing, but back end has stayed on Heroku because Vercel only currently offers headless RoR. Actively considering alternatives because of this.
