Build vs Buy: A Framework for Founders Choosing React Native App Templates

A developer-facing guide argues that most founders waste time debating whether to build a React Native app from scratch or buy a template, when the real question is where their product's differentiation lies. The framework suggests that if an app's uniqueness comes from its AI pipeline, marketplace logic, or workflow, founders should buy a template and redirect engineering effort toward those differentiators. Roughly 90% of consumer apps fall into this category, yet many founders mistakenly assume their infrastructure needs are unique enough to justify building from scratch. Full-stack templates, unlike basic UI kits, ship complete vertical stacks including database schemas, authentication, edge functions, and push notifications, saving an estimated 60-plus hours of setup work. The guide also addresses common concerns around originality and flexibility, noting that templates ship full source code and can be rebranded in an afternoon using tools like NativeWind.
