Best Mobile App Boilerplates in 2026 (React Native, Flutter, SwiftUI)

Shipping a mobile app means solving the same problems every time: authentication, in-app purchases, push setup, onboarding screens, App Store compliance. A good mobile app boilerplate handles that plumbing so you can spend your first week on the feature that makes your app worth downloading. A bad one locks you into someone else's architecture and costs you more time than it saves.

This guide covers ten mobile boilerplates from our catalog across four stacks: React Native with Expo, native SwiftUI for iOS, Flutter, and native Android with Kotlin. Prices range from $30 to $499, so there is a realistic option whether you are validating an idea or building for a client.

How we picked

Every product here is listed in the BoilerplateHub catalog, and every price was verified against the vendor's current pricing at the time of writing. We rank by stack fit rather than raw feature count: a $129 SwiftUI starter that matches your project beats a $499 monorepo you will never fully use.

React Native and Expo boilerplates

Cross-platform is the default choice for most solo founders, and React Native paired with Expo is the most mature way to do it in 2026. These four take different approaches to the same stack.

LaunchToday

LaunchToday is a $249 React Native and Expo boilerplate that supports both Firebase and Supabase as backends, which is unusual: most starters force you to pick one at purchase. It ships with AI features, chat, and ecommerce functionality, so it suits apps that are more than a CRUD wrapper, things like AI assistants, marketplaces, or anything with real-time messaging. The dual-backend support is also its honest tradeoff: maintaining two backend integrations means more surface area in the codebase, and you will end up deleting the half you do not use.

Native Express

Native Express costs $179 to $229 and takes a leaner path: React Native, Expo, Supabase, and TypeScript, with auth, payments, and a customizable UI layer. This is the pick if you want a typed codebase on a single opinionated backend rather than a buffet of options. The Supabase-only approach cuts both ways: if your project needs Firebase services like FCM-first push or Firestore, you are integrating those yourself. It is the sensible mid-range default for a standard subscription app.

AIO React Native & Next Template

The AIO React Native & Next Template is a $499 monorepo covering iOS, Android, and web from a single TypeScript codebase, with Expo and React Native on mobile and NextJS on web. If your product genuinely needs a real web app alongside the mobile clients, sharing types and logic across all three targets is worth paying for. The limitation is the price itself: at $499 it is the most expensive product on this list, and if you only need mobile, roughly half of what you are buying goes unused.

TurboStarter

TurboStarter runs $299 to $499 and covers the widest surface here: web via NextJS, mobile via Expo and React Native, and browser extensions via Plasmo, all backed by Supabase. It is aimed at founders building a product ecosystem rather than a single app, for example a tool with a web dashboard, a companion mobile app, and a Chrome extension. That breadth is also the caveat: a three-platform monorepo has a steeper learning curve than a mobile-only starter, and you should only pay for it if you will ship at least two of the three targets.

SwiftUI boilerplates (native iOS)

If your users are on iPhone and you want native performance, App Intents, and widgets without a bridge layer, SwiftUI starters get you to TestFlight fastest.

WrapFast

WrapFast costs $199 to $349 and is built specifically for iOS AI apps: SwiftUI, RevenueCat for in-app purchases, authentication, and a pre-built AI backend so you are not shipping API keys in the client. If you are building a ChatGPT-wrapper-style product or any app where an LLM call is the core loop, this is the most direct route in the catalog. The obvious constraint is that it is iOS only, so if Android turns out to matter for your market, none of this code comes with you.

SwiftyLaunch

SwiftyLaunch takes a different approach for $169 to $199: instead of handing you a repo, it generates a fresh Xcode project with your chosen modules, with Firebase or Supabase pre-integrated and RevenueCat wired in. The generator approach means less dead code to delete, which is a real advantage over clone-and-strip boilerplates. The flip side of generated projects is upgrades: once you have customized the output, pulling in improvements from newer generator versions is a manual job rather than a git merge.

SwiftShip

SwiftShip is the budget native option at a flat $129, covering the two things every paid iOS app needs: in-app purchases and authentication. It is deliberately smaller in scope than WrapFast or SwiftyLaunch, which makes it a good fit for a first App Store project or a weekend build where you mostly want IAP done correctly. The tradeoff is that scope: features the pricier SwiftUI kits bundle, like an AI backend or a project generator, are not part of the deal here, so budget time for anything beyond auth and payments.

Flutter boilerplates

Flutter remains the strongest alternative to React Native for cross-platform work, especially if you prefer Dart's tooling and a rendering engine that behaves identically on both platforms.

Fast Flutter

Fast Flutter is a general-purpose Flutter starter at $159 to $199, priced in line with the mid-range React Native options. It is the pick if you have already committed to Flutter and want a maintained foundation rather than assembling packages yourself. The catalog data on it is thinner than for the React Native entries, so review the vendor's feature list carefully before buying to confirm it covers your specific auth and payments needs.

ShipFlutter

ShipFlutter is the cheapest product on this list at $30, and it is focused: an ecommerce app template with Firebase and payments integrated. If you are building a shop-style app, that is a hard price to argue with, and even as a learning resource for Flutter plus Firebase it pays for itself. The limitation follows from the price: this is an ecommerce template, not a general SaaS starter, so if your app is not commerce-shaped you would be bending the architecture to fit.

Android native (Kotlin)

AppKickOff

AppKickOff is the only Kotlin-native option in the catalog, priced at $169 to $199, and like SwiftyLaunch it works as a starter code generator rather than a static repo. If your audience is Android-first, common in many markets outside North America, native Kotlin gives you better platform integration than any cross-platform layer. The constraint mirrors the SwiftUI kits: it is Android only, so an iOS launch later means a second codebase or a rewrite on a cross-platform stack.

Comparison table

Which should you choose

The real decision is not which boilerplate, it is cross-platform versus native. Everything else follows from that.

Choose cross-platform (React Native or Flutter) when you need both stores from day one, you are a solo developer or small team, and your app is mostly screens, forms, and API calls. That describes the majority of SaaS companion apps and consumer MVPs. One codebase halves your maintenance load, and modern Expo builds are close enough to native that users will not notice for typical apps. Within cross-platform, pick React Native if you or your team already write TypeScript and want to share code with a web app, and pick Flutter if you value pixel-identical rendering across platforms and do not mind Dart.

Choose native when the platform is the product. If you are building around iOS-specific surfaces like widgets, App Intents, Live Activities, or tight camera and sensor work, SwiftUI will fight you far less than any abstraction layer. The same logic applies to Kotlin on Android. Native also makes sense strategically when your entire market is on one platform: many indie iOS apps never need Android, and shipping a polished single-platform app beats shipping a mediocre one on two.

On budget: SwiftShip at $129 or ShipFlutter at $30 are enough to validate an idea. Spend $199 to $299 on the mid-range options when you are confident in the product. Only reach for the $499 monorepos when web is a genuine requirement, not a someday item.

Frequently Asked Questions

What is a mobile app boilerplate?

A mobile app boilerplate is a pre-built starter codebase that includes the infrastructure every app needs before it does anything useful: authentication, in-app purchases or subscriptions, push notification setup, onboarding flows, and often analytics and a backend integration. Instead of spending two to four weeks wiring these pieces together and debugging store review edge cases, you buy a tested foundation and start on your actual features from day one.

Is React Native or Flutter better for a boilerplate in 2026?

Neither wins outright, so decide by team fit. React Native with Expo is the better choice if you write TypeScript, want to share code or types with a web app, and value the huge JavaScript package ecosystem, which is why most premium mobile boilerplates like LaunchToday and Native Express target it. Flutter is the better choice if you want identical rendering on both platforms and prefer a single cohesive toolkit, and options like Fast Flutter and ShipFlutter cover that stack at lower price points.

Are mobile app boilerplates worth the money?

For most paid apps, yes, because the math is straightforward: correctly implementing subscriptions, receipt validation, auth, and store-compliant onboarding takes an experienced developer one to three weeks, and every product on this list costs less than a day or two of freelance rates. The exceptions are apps with unusual architectures that would fight the boilerplate's assumptions, and pure learning projects where writing the plumbing yourself is the point.

Can I build an iOS-only app with a cross-platform boilerplate?

You can, and it is a reasonable hedge if Android might matter later, but if you are confident your app stays iOS-only you are better served by a native SwiftUI starter like WrapFast, SwiftyLaunch, or SwiftShip. Native starters integrate directly with StoreKit, RevenueCat, and iOS-specific features without a bridge layer, produce smaller binaries, and never block on a cross-platform framework adding support for the latest iOS APIs.
