But it's probably to Render's credit that, in my opinion, the most annoying thing about Render is that it's impossible to google about Render because "render" is such a common word in the tech world!
Their support is good and responsive, and the developer experience was good enough. It has some warts, and there were definitely times I missed Heroku, but their speed of improvement gives me confidence in their future.
Sad to leave Heroku after almost a decade with them. They were far ahead of their time.
