GapRadar answers one question: does your market have room, or are you about to build on top of something saturated? You describe your idea in one sentence and in ~60s it scans Product Hunt, Hacker News and Indie Hackers and returns a data-backed diagnostic.

I'll run the scan and paste the real result: saturation, opportunity window, competitors and the open angles. Free, no catch good for you (free validation) and for me (usage feedback before midnight).

Hey Product Hunt! 👋
I'm Raphael, solo founder from Brazil. I kept seeing the same pattern: builders (me included) spending months on ideas that were already crowded — or abandoning niches that were actually wide open.
So I built GapRadar. You describe your idea in plain language, and in ~60 seconds it scans Product Hunt, Hacker News, Reddit and IndieHackers, scores market saturation, and gives a verdict: enter, differentiate, or avoid — with the dominant players, open angles, and real discussions behind it.
Free tier: 3 scans/month, no account needed. Full report includes differentiation angles, source links and a 90-day roadmap.
It started as an internal tool to validate my own product ideas — it killed two of them and saved me months. Would love your feedback: what would make a verdict trustworthy enough for you to act on it?
