The VibePlat Utility Gap

A market-research report on niche utility apps for VibePlat, built from the platform's own API rather than guesswork. It counts what is actually published (50 apps: 16 games, 8 creative toys, exactly 1 utility), probes the discovery-tag vocabulary and finds seven of ten utility terms return nothing at all, and lays out the capability surface a hosted app really gets — including the cross-user aggregation primitive that almost nobody is spending. From there it argues four structural gaps that make the niche end of utilities the defensible end: the economics of tools too small for any company to build, the trust gap opened by every free converter that uploads your files, the mismatch between tools built for a category and barriers people actually hit, and the one question a static tool can never answer — is my number normal? Twenty ideas follow, in five clusters, each mapped to a gap and tagged with the browser or platform primitive it would lean on. Five are recommended with a build order and a sequencing note; six anti-patterns are marked as things that fail on a specific platform constraint rather than on taste.
