I wanted to evaluate Render to host a node.js web service, and used the free tier to try it out. I love the ease of use and intuitive UI, but the free tier hibernation policies, along with it's general performance when not hibernating, prevented me from even evaluating it seriously, due to constant time-outs. I understand you need to limit the free tier in some form to incentivize upgrades to a paid plan, but I strongly suggest to find other avenues to do that. I will be looking elsewhere
