About GapQuery
App ecosystem intelligence for developers and micro SaaS founders.
Why GapQuery exists
Picking what to build next is the hardest part of being a solo developer or micro SaaS founder. "Gut feel" is a lousy way to do it when there is real data sitting right there on every app store, free for anyone to look at.
GapQuery started as a spreadsheet. I was scrolling the Shopify App Store for the hundredth time, trying to figure out which category was worth building in. I had half-formed theories about which niches were saturated and which weren't, but no way to verify them. So I wrote a scraper. Then ten more. Then I realized the real leverage was cross-ecosystem: knowing which categories thrive on Shopify but don't exist on WordPress, which integrations are missing, which apps get reviewed often but rated badly.
GapQuery is that spreadsheet, turned into a product.
What makes it different
Most "app ideas" content on the internet is opinion. GapQuery is data. 40,000+ apps, 184,000+ reviews, and 13,000+ integrations across 11 ecosystems, all normalized so you can ask questions like:
- Which Shopify categories have the highest demand and lowest supply?
- Which apps have 1,000+ reviews but under 3.5 stars? (Disruption targets.)
- Which integrations exist on QuickBooks but are missing on Xero?
- Which niche categories are growing versus stagnant?
- What's the median price for an app in a given category?
