I can second fly.io, I moved a bunch of personal (but "production") projects from Heroku to it recently (Node, Rust, Rails) and the experience has been great. I can also second their Heroku migrator, worked pretty flawlessly.
Overall, my pricing has been about the same or 5-10% less per month.
It doesn't have the same "Click this button to add this third-party service to your dynos, with billing included" eco-system that Heroku has (had?) but my Heroku usage was pretty vanilla so it wasn't an issue for me.
That's the one thing I haven't seen anywhere else. I think technically, for "run simple automatically built containers with little dev effort." there are many better solutions than heroku. The marketplace is the only existing differentiator for heroku, and I don't really understand why no-one seems to be trying to recreate it.
I get "marketplaces" are hard and there's a chicken/egg problem, but is anyone working on it? I think fly has the rest of it sorted and is clearly better. Would love to see the additional services as well.

I don't think that particular type of marketplace suffers from the chicken/egg problem, as that problem for me indicates when you must acquire two marketplace participants but it's hard to acquire one without the other.
But when it comes to integrations like this, you could easily write your own integrations as long as the platforms you try to integrate have APIs. Or contract freelancers to build those two. You don't need to have the platform owner to write the integration itself.
I guess I'd call it a "soft chicken/egg" problem rather than "hard".
