Create an Idea Validation Tool for Builders
11/15The Opportunity
Founders vibe-code their 15th SaaS with zero users. A pre-build demand scanner could save weeks of wasted effort.
Original Signal
“My agent just ran in a loop for 45 minutes burning $12 in API calls before I noticed. I have no idea where it got stuck or why it kept retrying the same tool call.”
Score Breakdown
11/15How urgently people need this solved and how willing they are to pay for it. Based on complaint frequency and spending signals across platforms.
How open the market is. A high score means few or no direct competitors, or existing solutions are overpriced and underdeliver.
How quickly a solo developer can ship an MVP. 5 = weekend project with standard tools. 1 = months of infrastructure work.
Existing Solutions
LangSmith has loop detection in traces but it's buried in observability noise and the free tier is limited. No standalone lightweight tool exists specifically for loop alerting.
Willingness to Pay
AI developers pay $20-49/mo for LangSmith or Helicone observability; a focused loop detector at $15/mo would be a cheap standalone alternative.
