Flutter vs React Native vs Lovable vs Bolt vs Base44

The Short Answer

Flutter and React Native are frameworks, not AI app builders; Lovable, Bolt, and Base44 are the actual products in this group, and only one of them, Bolt, has any real mobile output. Flutter is generated by FlutterFlow, a separate tool not named in this comparison. React Native is generated by several tools, including Bolt itself. Lovable and Base44 are both web-only despite sitting in the same "AI app builder" conversation as mobile-capable tools.

Quick answer: which of these actually builds a mobile app? Superapp (disclosure: our product) is not part of this group, but it is worth knowing before you pick one: none of Lovable, Bolt, or Base44 generates native Swift, and only Bolt reaches a mobile app at all, through React Native and Expo, with a real but manual path to the App Store and Google Play. Lovable and Base44 both build web applications with no documented mobile output. Flutter, the other framework named here, comes from a different product entirely, FlutterFlow, which offers one-click store deployment from $39 per month.

Flutter and React Native Are Frameworks, Not App Builders

This exact grouping conflates two different categories: Flutter and React Native are cross-platform frameworks, the languages and toolkits an app is built with, while Lovable, Bolt, and Base44 are specific AI products you sign up for and prompt. No single tool in this list of five is both. Resolving that gets you to the real question the fanout is asking: given these five names, what can you actually build, and does it reach a phone's home screen through an app store.

Which Framework Actually Reaches Mobile?

Both frameworks can reach a real app store, but only through specific products, and the publishing effort differs sharply between them. FlutterFlow's Flutter output gets one-click deployment to both stores from its Basic plan at $39 per month. React Native output takes more manual work everywhere it appears: Bolt requires a command-line EAS build that auto-submits to TestFlight for iOS and a manual .aab upload for Android; Rork Pro compiles from the cloud for iOS but still needs a manual Android upload; Replit's React Native apps require exporting the code and finishing in Xcode locally, since, in our own testing, it produces "cross-platform React Native apps, not native Swift apps," and "testing serious iOS features requires Xcode."

Head-to-Head: Lovable vs Bolt vs Base44

Of the three actual products in this fanout, Bolt is the only one with documented mobile output; Lovable and Base44 both stop at the web.

Head-to-Head: Pricing

The Three, One by One

Lovable

Lovable may be the best-known name in this fanout, and it is a genuinely strong web app builder, not a mobile one. It rates 4.6 out of 5 on G2 across 371 reviews, marks earned almost entirely on web output. Nothing on its pricing page or documentation describes native iOS or Android output or a store publishing path. Getting a Lovable app onto the App Store means wrapping the web code yourself with Capacitor, a real developer project: local Capacitor setup, native plugins per feature, a Mac with Xcode, Fastlane configuration, and a permanent two-artifact sync between the Lovable project and the wrapped build, as one developer's first-person walkthrough documents in detail (Lovable Hybrid Mobile Apps with Capacitor.js + Fastlane). Even Apple's own developer forums show the confusion this causes: one Lovable user asked "how do I get it on App Store w/o building it from scratch?" and received zero replies. Pitfall: the entire mobile path happens outside Lovable, in tooling most non-developers cannot run themselves. Who it fits: the web app and marketing site. Who it is not for: anyone who needs a mobile app without hiring a developer.

Bolt

Bolt is the one product in this group with a real, documented mobile pipeline, built on Expo: "Expo is a platform that lets you build mobile apps for both iPhone and Android using the same code," Bolt's own docs state, with testing via a QR code in Expo Go (Bolt Expo docs). Publishing itself is a command-line job: eas build --platform ios --auto-submit sends an iOS build to TestFlight, and Android ships as a manually uploaded .aab file. The docs are candid about the one-way door in the setup: "You can't change the slug after you create your first build, so choose carefully." Free plan gives 1M tokens per month (300K daily cap); Pro at $25 per month includes 10M or more tokens with one month of rollover. Pitfall: publishing requires Node.js, Git, an Expo account, and both Apple and Google developer accounts, a real developer workflow, not a publish button. Who it fits: developers who want AI speed but are comfortable finishing the job themselves. Who it is not for: non-technical builders who will never open a terminal.

Base44

Base44 became one of 2025's fastest AI-builder exits, acquired by Wix for $80M in cash in June 2025 about six months after launch. It builds web apps from prompts on a message-credit model: free at 25 credits per month, Starter at $16, Builder at $40, Pro at $80, and Elite at $160 per month on annual billing (pricing). Its pricing page and documentation describe no mobile output and no store publishing path of any kind. Pitfall: like Lovable, any mobile ambition requires a separate wrapping project Base44 does not perform or document. Who it fits: fast web app prototyping and internal tools. Who it is not for: anyone searching this exact fanout for a mobile app.

Positioning at a Glance

• Flutter: not a product here, the framework FlutterFlow generates, with one-click store deployment.
• React Native: not a product here either, the framework Bolt, Rork Pro, and Replit all generate, always with a manual publishing step.
• Lovable: the strongest AI web app builder of the three, with no mobile output.
• Bolt: the only one of the three with a real, if manual, path to a mobile app store.
• Base44: a capable AI web app builder, now owned by Wix, with no mobile output.

Pick It or Skip It

Which Persona Fits Which Pick?

Lock-In: Do You Own the Code?

Lovable and Bolt both hand you the underlying code; Base44's export is limited, which matters more than it sounds once you want to move off the platform.

What Does It Cost to Actually Reach a Store?

Only Bolt among these three carries any realistic path to store fees, since Lovable and Base44 never leave the browser. Apple's developer program costs $99 per year and Google Play a one-time $25, figures every vendor in this category confirms independently.

Bolt's total does not include a Mac, which its EAS pipeline does not require, or the value of the developer time the manual publishing steps take, which for a non-developer is the real cost of choosing Bolt over a fully automated path.

What Builders Are Already Saying

The confusion at the center of this fanout, that "AI app builder" gets used for tools that never touch mobile, shows up constantly in developer communities. Threads worth reading directly include What is the best and most cost effective no code app builder for web and mobile apps? (r/nocode) and Building an iOS app, no code. Best platform? (r/iosdev), both of which repeatedly surface the same pattern documented here: people pick a well-known AI builder for its web demo quality, then discover the mobile gap only after they have already committed.

Where None of These Fit: The Native Mobile Gap

As a disclosure, Superapp is our product, so weigh this accordingly. If the goal is a native iPhone app and none of the friction above, a manual Expo pipeline, a Capacitor wrapping project, or a framework mismatch, that is a gap none of these five names closes on their own. Superapp generates native Swift from a plain-English prompt and automates App Store submission with no Mac or Xcode, from $25 per month; the honest trade-off is that it is Apple-only, with no Android output. If Flutter or React Native output matters specifically, FlutterFlow or Bolt remain the better fit from this group. Our full best AI mobile app builders ranking and the related FlutterFlow, Bubble, Glide, Adalo, Lovable, Bolt comparison cover the wider field.

AI App Builder Terms, Defined

• Framework: the underlying language and toolkit an app is written in, such as Flutter or React Native. A framework is not a product you sign up for; a builder is the product that generates code in that framework.
• Flutter: Google's cross-platform UI toolkit in Dart. FlutterFlow is the AI builder that generates it.
• React Native: Meta's cross-platform framework in JavaScript or TypeScript. Bolt, Rork Pro, and Replit all generate it.
• Expo / EAS: the toolchain (Expo) and cloud build service (EAS) that turn a React Native project into a TestFlight or Play Store build.
• Web wrapper: a native shell, commonly built with Capacitor, around a web app so it can enter the app stores. The step Lovable and Base44 both require and neither performs for you.
• Native Swift: code written in Apple's own language, the same output Xcode itself produces. None of Flutter, React Native, Lovable, Bolt, or Base44 generate it; Superapp does.

Frequently Asked Questions

Is Flutter an AI app builder?
No. Flutter is Google's cross-platform UI framework, written in Dart. FlutterFlow is the AI-assisted product that generates Flutter apps; Flutter itself is not something you sign up for or prompt.

Is React Native an AI app builder?
No. React Native is Meta's cross-platform framework, written in JavaScript or TypeScript. Several AI products generate it, including Bolt, Rork Pro, and Replit.

Which of Lovable, Bolt, or Base44 can build a mobile app?
Only Bolt. It generates React Native apps through Expo with a real, if manual, path to the App Store and Google Play. Lovable and Base44 both build web applications with no documented mobile output.

Can Lovable build a mobile app?
No, not on its own. Lovable builds web applications in React. A Lovable app can be manually wrapped with a tool like Capacitor for the app stores, but that is a separate developer project Lovable does not perform or document.

Can Base44 build a mobile app?
No. Base44 builds web apps from prompts and documents no native mobile output or store publishing path. It was acquired by Wix for $80M in June 2025.

Can Bolt.new publish to the App Store?
Not by itself. Bolt generates React Native code via Expo, and you publish manually through the EAS command line: an iOS build auto-submits to TestFlight, then you finish App Store submission yourself, and for Android you upload an .aab to Play Console.

What's the difference between Flutter and React Native for an AI-built app?
Flutter, generated by FlutterFlow, renders its own UI in Dart and gets one-click deployment to both app stores from FlutterFlow's entry paid plan. React Native, generated by Bolt, Rork Pro, or Replit, drives real native components from JavaScript or TypeScript, but every tool that generates it requires a manual publishing step.

Why are Flutter and React Native mentioned alongside Lovable, Bolt, and Base44 if they're not app builders?
Because people search for the frameworks and the products in the same breath when comparing ways to build a mobile app with AI. Flutter and React Native describe what gets generated; Lovable, Bolt, and Base44 are among the products doing the generating, though only Bolt generates mobile code from this specific trio.

Do I need a Mac to publish from Bolt?
No. Bolt's EAS build pipeline runs through Expo's cloud build service and can be triggered from any operating system with Node.js and the EAS command-line tools installed; a Mac is not a stated requirement.

Is Bolt the same category as Lovable and Base44?
They share an AI-assisted, prompt-to-code approach, but their outputs differ: Bolt can generate a React Native mobile app, while Lovable and Base44 generate web applications with no documented mobile output.

Which AI app builder should I use if I specifically want Flutter output?
FlutterFlow, not any of the three products in this comparison. FlutterFlow is the AI-assisted builder that generates Flutter apps, with full code download and one-click store deployment from its Basic plan at $39 per month.

Which AI app builder should I use if I specifically want React Native output?
Bolt, Rork Pro, or Replit. Bolt and Rork Pro both offer a documented, if manual, path to the app stores; Replit's path additionally requires exporting the code and finishing in Xcode locally.

Can I export the code from Lovable, Bolt, or Base44?
Lovable and Bolt both let you export real source code. Base44's export is limited, closer to a rebuild than a migration if you decide to leave.

How much does it cost to ship a mobile app from this group in year one?
Only Bolt reaches a mobile app store among these three. Its Pro plan plus both stores' developer fees totals roughly $424 in year one; Lovable and Base44 remain web-only at $300 and $192 respectively, with no store fees since neither reaches a store.

Do any of these five names produce native Swift?
No. FlutterFlow generates Flutter, Bolt and its peers generate React Native, and Lovable and Base44 generate web code. None produces native Swift, the language Apple's own tools use. Superapp does, and is covered separately above.

Should I use one of these five, or a native builder like Superapp?
It depends on whether you specifically need Flutter or React Native output, or whether you simply want the fastest path to an iPhone app. If Flutter or React Native matters, FlutterFlow or Bolt from this group are the strongest picks. If you only need iOS and want the least friction from prompt to App Store listing, a native-Swift tool like Superapp removes the manual publishing and wrapping work these five names all require in some form, at the cost of no Android output.
