Yep! Used Heroku at a previous gig (now a mid-size startup), worked great, now on Render.com and it's also great. Also factor in fly.io and railway as quickly-growing platforms in the same PaaS sort of space.
I head up Dev Advocacy at Render (previously at Heroku). Happy to answer any questions about Render.
I'm really only waiting on PITR for postgres before moving all my workloads over to render. Do you know when that will be available?
(Render CEO) We're targeting early next year, but it might be sooner if we can hire faster!
Other competitors like render.com are starting to look like they'll be competitive on features and are way cheaper too.
