Picking a cross-platform framework is a decision you’ll live with for years. You’ll hire for it, build your release process around it, and inherit its upgrade cycle.
All five frameworks have changed a lot since we originally published this article.
React Native now talks to native code directly, Flutter runs on its own rendering engine, and Kotlin Multiplatform can share your UI as well as your logic.
Here, we’ll compare the five frameworks worth evaluating in 2026, what each one does best, and which teams each one suits.
Cross-platform apps run on multiple operating systems, like Android and iOS, from a single codebase. You don’t write separate code for each platform.
That changes how you deliver. Instead of two native teams working in parallel, you get one codebase, one release process, and far less duplicated logic.
The savings can be large. On the eBay Motors app, 98.3% of the code was shared across iOS and Android.

eBay Motors also shows what that does to a timeline. In 2019, a small team had under a year to launch new apps on both Android and iOS, from concept to release.
Two native apps in that time wasn’t realistic. With Flutter, they launched the beta in three months and shipped the full app in 2020.
In a team survey, 70% of developers said Flutter was at least twice as fast as native development.
The top 5 cross-platform frameworks in 2026 are:
Flutter and React Native are still the two dominant choices. In August 2026, the react-native package recorded 50.2 million monthly downloads on npm, and Flutter’s package registry listed 76,922 packages.
Kotlin Multiplatform is smaller but growing fast. JetBrains’ library index passed 4,200 Kotlin Multiplatform projects in August 2026.
If you’re just looking for a quick overview, we’ve got you covered. Here’s a quick comparison across key categories:
Cross-platform mobile app development frameworks: overview
| Framework | Platforms | Main benefits | Main flaws | Notable apps |
|---|---|---|---|---|
| Flutter | iOS, Android, web, desktop | Consistent UI across platforms through its own rendering engine | Larger app size, Dart learning curve | Google Pay, BMW, Alibaba, eBay Motors, Wolt |
| React Native | iOS, Android, web, Windows, macOS | Large ecosystem, direct native access, familiar to JavaScript teams | Upgrade work on major versions, reliance on third-party native modules | Facebook, Instagram, Microsoft Outlook, Shopify |
| Kotlin Multiplatform | iOS, Android, web, desktop, server | Shared logic with native UI, or shared UI through Compose Multiplatform | Smaller ecosystem, iOS tooling still maturing | Google Docs, Duolingo, Cash App, McDonald’s |
| .NET MAUI | iOS, Android, macOS, Windows, tvOS | Microsoft stack integration and tooling | Microsoft dependency, 18-month support windows | Fidelity, NBC Sports Next, Azure mobile app |
| Ionic | iOS, Android, web | Easy entry for web developers | Web view rendering limits complex UI, paid services discontinued | Southwest Airlines, Shipt, H&R Block, NHS |
Here, we’ll discuss the frameworks we mentioned in more detail – their key features, pros and cons, and the top apps built using each framework.
Flutter is Google’s open-source framework for building cross-platform apps from a single Dart codebase.
It compiles to native ARM code, so apps run fast on both iOS and Android.
It’s a strong fit for apps that need custom, brand-heavy interfaces and complex animations.
source: Flutter Docs
Flutter draws every pixel itself instead of using each platform’s native components.
Its rendering engine, Impeller, is now the default on iOS, Android, and desktop, and it removes the stutter older versions had when compiling shaders.
That’s why Flutter apps look identical on every device. Everything on screen is a widget, from layouts to buttons and text, and you control all of it.
If you’re starting a project now, note one change. Flutter 3.47 moved Material and Cupertino, its built-in Android and iOS design libraries, into separate packages you add on purpose.
In Flutter, you can see code changes in real-time and you don’t need to restart your app – this can save you a lot of time.
Flutter has a rich set of customizable widgets with per-pixel Skia rendering for adaptive, polished designs, so you can quickly create great-looking UIs for your app.
Flutter easily integrates with Firebase, which simplifies backend development.
Ahead-of-time compilation gives smooth animations and fast startup.
Platform channels and plugins connect to the camera, sensors, and other device features.
Flutter has a very active community and a huge package library (pub.dev) with a wide range of plugins and pre-built solutions.
Some of the top apps built with Flutter, listed on Google’s showcase, are:
Choose Flutter when your app’s interface is a big part of the product and you want it to look the same everywhere.
React Native is Meta’s open-source framework for building mobile apps with JavaScript and React.
It renders real native components, so your app looks and behaves like a native one.
And if your web team already writes React, much of what they know carries over.
The biggest recent change is under the hood. The old asynchronous bridge, which passed every message between JavaScript and native code, is gone.
Its replacement, the New Architecture, became the default in 0.76, and version 0.84 removed the legacy code in February 2026.
source: React Native
JavaScript now calls native code directly through the JavaScript Interface (JSI), without converting data in between.
React Native also works alongside existing iOS and Android code, and Microsoft maintains Windows and macOS support.
For new apps, React Native’s docs recommend starting with a framework and name Expo.
Expo handles native setup, cloud builds, and over-the-air updates on top of standard React Native. Its hosted services are free for small projects and paid at team scale.
Your app uses each platform’s real UI components, making it feel just like a native app.
See code changes instantly while keeping the app’s state.
React Native can integrate with a huge number of libraries, tools, and frameworks to extend its functionality.
You can use React paradigms (JSX, props, state) to build a clean, modular UI.
Hermes engine support, auto-batching, Suspense, TypeScript default, improved bridging – just to name a few.
Some of the top apps built with React Native, listed on the official showcase, are:
Choose React Native when your team already works in JavaScript or TypeScript and you want the biggest ecosystem to draw from.
.NET Multi-platform App UI (.NET MAUI) is Microsoft’s framework for building cross-platform apps with C# and .NET.
It’s the successor to Xamarin. One project can target iOS, Android, macOS, Windows, and tvOS, and if your team already works in .NET, there’s no new language to learn.
source: Microsoft Learn
MAUI uses each platform’s native controls, and you can still call platform-specific features when you need them.
It works well with Visual Studio, Azure, Microsoft 365, and existing .NET backends.
Plan for its release cycle.
Microsoft ships a new version every year, and MAUI 10’s support ends on May 11, 2027. .NET 11, now in preview, switches the default runtime, which affects app size, performance, and debugging.
You can use one C#/.NET project targeting Android, iOS, macOS, Windows, and tvOS – no need for platform-specific projects.
.NET MAUI apps use each platform’s own UI components for a native look and feel.
You can modify XAML or C# code during runtime and instantly see changes without restarting the app
Hosts web UIs using BlazorWebView or HybridWebView to share web/native logic.
Full IDE support, debugging tools, and extensive open-source libraries .
Some of the top apps built with .NET MAUI, listed on Microsoft’s customer showcase, are:
Choose .NET MAUI when your company runs on Microsoft tools and you’re building internal or enterprise apps.
Kotlin Multiplatform is JetBrains’ open-source technology for sharing Kotlin code across platforms.
It lets you share business logic, like data models, networking, and business rules, while each platform keeps its native UI. That cuts duplicated code and bugs.
source: Kotlin
You don’t have to start from scratch. You can add Kotlin Multiplatform to existing apps one module at a time, which makes it a good fit for teams that already have native apps in production.
You can also share the UI.
Compose Multiplatform, built on top of Kotlin Multiplatform, uses Google’s Jetpack Compose to render one interface on iOS, Android, and desktop.
It’s been stable on iOS since May 2025. If your Android team already writes Compose, most of what they know transfers. The web version is still in beta.
Share only logic, specific modules, or the full UI, depending on what you need.
Shared code calls directly into your existing iOS and Android codebases.
Kotlin Multiplatform supports Gradle, a build automation tool, which simplifies dependency management and improves productivity.
You can mix Compose screens into existing SwiftUI and UIKit apps, and move more over as you go
Some of the top apps built with Kotlin Multiplatform, listed on JetBrains’ use cases page, are:
Choose Kotlin Multiplatform when you have native apps or a strong Android team and want to share code without a rewrite.
Ionic is an open-source toolkit for building mobile apps with HTML, CSS, and JavaScript.
It’s easy to pick up for web developers and works with Angular, React, and Vue.
Ionic uses Capacitor to access device features like the camera, location, and push notifications.
Your interface still runs inside a web view, a browser window embedded in the app, so complex animations hit limits sooner than in the other four frameworks.
There’s one business change to know about. In February 2025, Ionic stopped selling its commercial products, including the Appflow build service. Existing customers keep Appflow access until December 31, 2027.
The open-source framework is still actively maintained. OutSystems, which owns Ionic, has committed to supporting it and Capacitor. If you rely on Appflow, plan a replacement before the end of 2027.
Ionic uses HTML, CSS, and JavaScript to build cross-platform mobile apps, so it’s an easy transition for web developers.
Open-source runtime environment that connects your app to native device features.
Cards, lists, tabs, and more that adapt to iOS and Android design.
Works with Angular, React, Vue, or plain JavaScript
Some of the top apps built with Ionic, listed on Ionic’s customer page, are:
Choose Ionic when you have a web team, a content-focused app, and need to ship on mobile quickly.
There’s no single best framework. The right one depends on your team, your app, and your long-term plans.
Start with what your team already knows. The more familiar the tech, the faster they can master it.
Pick the framework your team can be productive in within weeks.
Most business apps are forms, lists, and screens that load data from a server. Any of the five frameworks handles that well.
If your app relies on complex animations or constantly redraws the screen, Flutter’s rendering engine gives you the most predictable results across devices.
One codebase doesn’t mean identical behavior. Date pickers, keyboards, safe areas, and the back gesture all work differently on iOS and Android.
Emulators also hide problems like overheating, battery drain, and low-memory crashes. Test on real devices on both platforms from the first sprint.
Flutter and React Native both ship on predictable schedules with public roadmaps.
Kotlin Multiplatform has JetBrains and Google behind it.
For .NET MAUI and Ionic, put the support dates in your plan now. MAUI 10 support ends May 11, 2027, and Appflow access ends December 31, 2027.
Neither rules the framework out, but you should know your upgrade path before development starts.
Lynx, open-sourced by ByteDance in 2025, reached version 4.0 in July 2026 and renders natively on iOS, Android, and web.
Its main production users so far are ByteDance’s own apps, TikTok and CapCut, and its 2026 roadmap lists device APIs and tooling as work in progress.
It’s worth tracking, but it’s early for a client project.
Very close, especially with Flutter and React Native. Flutter compiles to native code and draws through its own Impeller engine, so performance stays consistent across devices.
React Native now calls native code directly, with no bridge in between. For typical business apps, users won’t notice a difference from native.
For the hardest cases, like real-time video processing or complex 3D, fully native code (Swift or Kotlin) or a game engine like Unity is still the better choice.
It depends on what you need. Flutter gives you more control over the UI and more consistent rendering, because it draws everything itself.
The trade-offs are Dart, which has a smaller hiring pool than JavaScript, and larger app sizes.
React Native uses JavaScript, renders native components, and has a larger ecosystem for third-party integrations. Its main costs are upgrade work and waiting on third-party libraries to catch up.
Choose Flutter for UI control. Choose React Native if your team knows JavaScript and you want to move faster.
React Native is the natural fit. You use the same language, libraries, and tooling you already use on the web, and TypeScript works out of the box.
Most new React Native apps start with Expo, which handles native setup and builds for you.
Ionic is the other option, especially for content-focused apps. It runs in a web view, though, so complex animations will hit limits sooner.
