What is the tech stack used in Hashnode? How does that scale? How good is it in terms of server bills?
I have been recently researching about server costs of various tech-stacks and it is interesting to know how much it costs to run these things. I came to know of one site which was written in C# which required 12 times more server costs than a similar app with same functionality written in Laravel(PHP) required.
Also, is it opensource?
