Check if other startups actually make money from ideas similar to yours. Reddit demand validation pulls from nearly 200,000 trending topics—shows what people complain about or ask for repeatedly.
For indie developers? Less guessing. Say you're thinking about an AI productivity tool. Build Or Not shows which competitors exist. How they monetize. Where users grumble in the App Store. Whether Reddit threads suggest real demand. It syncs with HuggingFace for AI model trends. Pulls from 234 payment platforms for revenue data.
Here's the catch with free access. You get unlimited AI model data. Browse Reddit startup ideas endlessly. Everything else? Capped at 100 items preview. That's barely enough to make decisions.
Basic ($20/mo) unlocks 2,000 App Store opportunities and 1,000 startup revenue cases. Advanced ($30/mo) goes to 30,000 revenue records. Pro ($50/mo) adds one-on-one support.
The gap between free and paid feels intentional. You can browse enough to see it works—not enough to validate an actual business idea. That pushes most serious users toward at least Basic tier.
