Hey HN, I'm Pieter, maker of stackco.st. The idea came from a simple frustration — every time I was evaluating a new tool, I'd google "[tool name] pricing" and get either the official pricing page or a two-year-old blog post. I never found what real founders at my stage actually paid, with their actual stack, at their actual MRR. So I built a place where founders share their full SaaS stack and monthly bill. Not curated, not sponsored — just real numbers. You can see what a pre-revenue founder spends versus someone at $5K MRR. You can spot where people overpay. You can find cheaper alternatives people actually use. It's two days old and has four stacks including my own. I know that's basically nothing, but I wanted to put it in front of people who'd tell me honestly if this is useful or a waste of time. Happy to answer anything — including the hard questions.
