I’ve seen a lot of people spend weeks building side projects before ever asking whether the idea itself makes sense. Usually the excitement comes first, and validation happens much later, if at all.
Build Check is a simple tool built around that exact problem.
You answer a short set of questions about your app idea, and it scores the concept across several dimensions to help estimate whether it’s actually worth pursuing. The target audience seems pretty clear too: indie hackers, first-time founders, and “vibe coders” who can build quickly but may not always stop to evaluate demand first.
What I like about it is that it doesn’t pretend to predict startup success with perfect accuracy. It feels more like a structured reality check before committing serious time to something.
The scoring framework looks at areas like:
- market demand
- competition
- distribution difficulty
- monetization potential
- execution risk
A lot of builders don’t really need another productivity tool. They need something that helps them avoid building the wrong thing in the first place, and that’s the gap this product is trying to fill.
