Gapstr

Gapstr is an AI founder intelligence tool that scans Hacker News, GitHub, and Stack Overflow to surface unmet market demand for indie hackers and solo founders. It fits the startup-tools category by turning developer and community discussions into buildable product ideas: you type any keyword and get an opportunity score broken into demand, competition, and revenue-potential components, plus an AI-powered market analysis. Each result also includes a complete MVP plan with a sprint schedule and a ready-to-paste prompt for Cursor or Claude Code, so you can move from idea to build without rewriting the brief yourself. The homepage shows a sample "Today's Opportunity" with a score of 91 for an AI invoice tool for freelancers, listing signal sources such as Hacker News, GitHub issues, and product reviews, and suggesting an MVP path and price range. Gapstr states it is free with no login required and is currently in beta with early access. For founders comparing the best AI for finding startup ideas, Gapstr's multi-source demand scanning and copy-paste build prompts are its defining features.

Indie hackers and solo founders who want to find validated, underserved product ideas and a ready-to-build MVP plan.
