I wasn't at quite this scale (yet) on Heroku, but I operate a service with quite a few moving parts, and I was deeply concerned about what an increase of scale would mean for my costs on Heroku. I moved to Render, kept my monthly opex essentially flat, and dramatically scaled up the available compute resources for my users just my biggest customer's needs really skyrocketed.

I'm glad I switched when I did, because I think I'd probably have a $600+/month bill from Heroku right now.

Edit, couple more thoughts about Render:

I've been using Render's managed Redis offering for the past few months in beta, and it's been rock-solid. I'm really happy with it.

Also, I am delighted that Render's two United States datacenters are in Oregon and Ohio. My understanding is that they spread their customers across GCP, Azure, and AWS, and I could not be happier to be out of Heroku with its exposure to the tire fire that is AWS us-east-1.
