Trend Gap

TrendGap helps indie hackers, solo builders, no-code teams, and founders identify SaaS and mobile app ideas with real demand. It analyzes large volumes of user reviews and complaints, then ranks the best opportunities by a Market Pain Score so you can focus on gaps with clear intent.

It’s geared toward people who don’t want to guess what customers want. Instead of broad trend lists, it points to specific pain points drawn from real review text and links back to where the signals came from.

• Review mining at scale scans 100,000+ app reviews weekly across sources like G2, TrustPilot, App Store, Capterra, and Product Hunt (plus community signals like Reddit)
• Market Pain Score ranking clusters complaints and highlights the highest-pain, lower-competition niches
• Validated opportunity reports show top pain points with links back to the underlying reviews
• Blueprint output provides a ready-to-ship blueprint, including tech stack recommendations and GTM playbook guidance for the niche
• Continuous updates keeps analyses running so new signals appear over time, not once and then stale

TrendGap also shows competitive density alongside example incumbents so you can judge how crowded the space looks. In addition, it supports a “started building it” claim workflow that links approved builders’ products to the idea card (with revenue proof reviewed manually).
