Evidence, not vibes
Separate observable signals from interpretation. Every score points back to its evidence.
Stop building SaaS nobody wants.
BuildCheck validates demand, competition and distribution before you — or your coding agent — spend weeks building the wrong product.

Your coding agent can code. But should it?
Give your coding agent permission to say no — or to propose the smallest validation MVP worth building first.

Your AI knows how to code. BuildCheck tells it what’s worth coding.
See the market case, the failure case and the cheapest validation test in one explainable report.
Deterministic Build Score
Demand, pain, pricing, distribution, competition, simplicity and defensibility — weighted in code.
Roast before you build
Attack weak assumptions and define exactly what evidence would change the verdict.
Discover real problems
Start from repeated frustrations and costly workarounds, not a solution looking for a market.
Protect your tokens
Estimate implementation cost and shrink the idea into a test you can run this afternoon.
Built for AI-native builders
Service boundaries are ready for a future MCP without coupling product logic to the UI.
Demo workspace included
Kill weak ideas before they kill your roadmap.
No API key required. The demo uses a transparent, curated dataset and the same deterministic scoring engine as future live-source analyses.
