Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.
What each says it does
StackGen
AI-powered DevOps assistant for managing cloud infrastructure and applications.
expo-stack
Scaffolds a production-grade Expo app on one opinionated stack — Expo Router + Convex (cloud or self-hosted) + Better Auth + Uniwind + react-i18next + pre/post sign-in onboarding, with an Expo-UI-first UI layer (FlashList v2, TrueSheet, keyboard-controller, gifted-charts, calendars, pager-view), a react-native-ease / Reanimated / Skia motion split, deep linking through +native-intent (Universal/App Links plus the deferred-install gap), a premium-UI audit that verifies on a real device via argent alongside a screenshot-driven visual-design critique, revenue decisions backed by subscription data (trial length, hard vs freemium, Android billing recovery), ASO as part of the ship loop, and post-scaffold commands — /setup, /rebrand, /customize-onboarding, /configure-monetization, /add-language, /ship. Always resolves the latest Expo SDK — nothing is pinned except the mandatory better-auth version set, which is derived from the Convex component. bun/pnpm/yarn workspaces with the hoisting React Native actually needs
