Why you can trust the picks

No hype, no vanity metrics. Here’s exactly how an opportunity earns its spot.

Commercial viability gate

Every opportunity is scored on buyer clarity, budget ownership, existing spend, and ROI before it’s shown. Weak ideas get filtered out — not dressed up.

Built on real developer signal

Thousands of posts from Hacker News, GitHub, Stack Overflow and Product Hunt — actual complaints and feature requests, never surveys or guesswork.

Computed verdicts, not opinions

BUILD / INVESTIGATE / SKIP is a calculated score from signal strength × commercial evidence. You see the reasoning and sources behind every call.

Niche Sonar shows its work. Built by a solo founder who got tired of guessing what to build, it surfaces every score, source link, and reason behind a pick — so you can judge the evidence yourself instead of taking anyone’s word for it.
