I’ve tried Render recently and overall i liked the experience with setup and configuration of my stack.
Although the performance was abysmal. It’s either their compute or postgres, but my import of 25mb json via a script took 22 minutes ($450/month) on job plan, while my 2GB digital ocean box did the same in 3 minutes.
Also email support takes 3 business days to respond.
But render has great potential. If they fix the performance and straighten out the support, they would definitely win over a lot of heroku customers.
Probably will just migrate to Dokky and be done with it.
