Hi, Is it possible for me to serve dynamic content from a free mongodb atlas cluster with nodejs to netlify free tier?
Sure, as long as you have a “free mongodb atlas cluster” which we don’t provide. We don’t put any restrictions on what you serve from what systems except that it must be legal and abide by our ToS which is service-agnostic.
Do be aware that we don’t “run nodejs” for you - except to build your site - our hosting philosophy is described here: https://jamstack.org/
