What will it cost
to run your idea?
Pick a stack, drag your expected users, and see the rough monthly bill. The honest answer for almost every vibe-coded idea at launch is nothing, and this shows you roughly when that changes.
At 1k users on Next.js + Postgres, this runs for nothing. You start paying somewhere past 1k users.
Launch is free. Traction is the bill.
This is the number people overestimate most. A new product on any of these stacks costs nothing to run until it has real users, so the thing standing between you and a live product is not a hosting bill, it is the build and the distribution. Spend the worry there instead.
Frequently asked
Is this a real quote?
No, it is a directional estimate. Cloud pricing changes and a real bill depends on how heavy each user is, so this works in ranges and free-tier thresholds. Treat it as a ballpark, not an invoice.
Why is it $0 at launch?
Because every stack here has a genuinely generous free tier. A solo builder with a new product almost never pays for hosting, database, or storage until there is real usage. That is the honest headline: you can launch for nothing.
When do I actually start paying?
Roughly when you pass the free-tier threshold shown for your stack, which is usually thousands of active users, not tens. The paid step is often one flat move, not a slow creep.
Does this include my own time?
No, only the infrastructure to run it. Your time is the real cost of any build, which is what the MVP time estimator is for.
Which stack is cheapest?
Usually the edge stacks, because their free tiers are the most generous and they scale in small steps. But the cheapest stack you cannot build on is no bargain, so pick the one you already know well, and then read what running it here would cost.
What is not in this number?
Your domain, any paid API the idea itself calls, and email sending past a free allowance. Those are per-idea rather than per-stack, so the build notes on each idea name the ones that matter.
