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.
