Yep, same situation. Looked into render. I liked what I saw (and spun up a trial). But it was going to be expensive for a bunch of low usage projects.
I ultimately went with a large-ish droplet from DO with dokku installed. It’s been great, for the many small sites use case. It doesn’t scale, but that’s fine. When projects get traction the intention is to move them.
Which one has, and is now on AWS. But if we’d been on render I wouldn’t have moved it. I’d just spin up its own db and scale up the processes.
