Heroku was / is like a mainframe. You get provisioning, scaling, configuration, etc all sorted out for you, as long as you pay through the nose.

I kind of think Railway and Fly.io is taking that spirit forward? Although I would love if Salesforce would just sell Heroku to somebody else and take it forward.

So, it's a price issue? My confusion / out-of-the-loop is thus: I hear that Heroku has gone downhill, is no longer recommended etc, yet I've noticed no degradation personally. Works well, is stable, has all the benefits I initially liked it for.
