What it is

Build Check is a free quiz-based tool that helps non-technical founders and vibe coders evaluate whether their app idea is worth pursuing. It scores ideas across six dimensions to surface strengths and weaknesses before any time or money is invested. The goal is to reduce wasted effort by giving early-stage builders an honest, structured reality check.
