Show HN: Free MVP cost estimator – see what agencies charge vs. a 72-hour sprint

Built this after watching too many founders get quoted $40k for something that takes 72 hours to build.

You describe your app idea in plain English. Gemini AI breaks it down into real technical components and generates a realistic agency cost estimate with timeline and team size. Then you can see the lean MVP alternative.

No signup required to see the agency estimate. Curious whether the cost estimates feel accurate to people who have actually been through this — and whether the technical breakdowns match what you have seen in the wild.
