Build.io came out of this exact problem a few years ago (I joined in 25Q4) - trying to be what Heroku could have been if it had continued to evolve.

We offer the same default simplicity/speed, but with the ability to go deeper once teams hit scale, cost, or workflow limits. Plus a pricing model that stays understandable and improves as teams scale rather than punishing them for it.

Fair warning: the website is pretty light right now. It’s mostly a placeholder while we prep a broader push over the few months. Happy to answer questions here if helpful.
