Agreed. I actually have not too much problem with heroku pricing (I could complain about some areas, but it's working for us) -- I'm just worried that heroku seems to be slowly disintegrating through lack of investment, so am worried that there seem to be no other realistic options for that level of service! There don't seem to be other reliable options for managed PaaS that takes care of maintenance in the same way.

I've seen render.com thrown around a bit as an alternative. Haven't tried it out myself though.

There's also netlify, vercel and similar sites but I think they're mainly geared toward all-javascript apps.
