Mobile Development Platforms & Cross-Platform brand directory

Kotlin Multiplatform (KMP) is JetBrains' production-ready, Apache 2.0-licensed cross-platform development technology that lets developers write shared Kotlin code once and deploy it across Android, iOS, desktop, web, and server, with optional full UI sharing via Compose Multiplatform.

Expo is a full-stack React Native framework and managed cloud platform (EAS) that enables JavaScript and TypeScript developers to build, deploy, and maintain production-grade native apps for iOS, Android, and the web from a single codebase. Its SDK provides 100+ native modules; its cloud services automate builds, over-the-air updates, app store submissions, CI/CD pipelines, and web hosting—covering the entire mobile app lifecycle.

Flutter is Google's open-source, multi-platform UI SDK that lets developers write a single Dart codebase and deploy natively compiled applications to iOS, Android, web (including WebAssembly), Windows, macOS, Linux, and embedded devices. It uses its own high-performance rendering engine (Skia/Impeller) to render widgets pixel-by-pixel, enabling consistent, brand-driven UIs without relying on platform-native widget systems. Key developer productivity features include stateful hot reload, a rich built-in widget library, Flutter DevTools, and a 30,000+ package ecosystem on pub.dev.

React Native is Meta's open-source JavaScript framework for building natively rendered mobile applications for iOS, Android, and an expanding set of platforms from a single React codebase. It bridges JavaScript business logic and UI definitions to real native platform components via its New Architecture (JSI, Fabric, TurboModules), offering near-native performance while enabling web developers to apply React skills to mobile development. The framework is used in production by thousands of companies—from startups to enterprises such as Microsoft, Shopify, and Bloomberg—and is supported by a large global community and regular Meta-led releases.

Ionic is a web-first cross-platform mobile development platform providing an open-source UI component library (Ionic Framework), a native device bridge (Capacitor), and—historically—enterprise-grade CI/CD (Appflow), security components, and micro-frontend infrastructure (Portals). Now an OutSystems subsidiary, Ionic's open-source core remains actively developed while its commercial product suite has been sunset for new buyers.

.NET MAUI is Microsoft's open-source cross-platform UI framework enabling C# developers to build native Android, iOS, macOS, and Windows applications from a single codebase and project, released in 2022 as the successor to Xamarin.Forms.

Capacitor is the open-source native runtime layer at the heart of the Ionic/OutSystems mobile ecosystem. It converts any web app—regardless of the JavaScript framework used—into a publishable native app for iOS, Android, and the web by embedding a WebView inside a true native iOS (Swift/Xcode) or Android (Kotlin/Java/Android Studio) project shell, and providing a typed JavaScript plugin API that bridges web code to native device SDKs.

NativeScript is a free, open-source JavaScript/TypeScript framework for building truly native mobile apps for iOS, Android, and visionOS from a single codebase. It exposes 100% of native platform APIs directly to the JS runtime—no WebView, no bridge—and supports Angular, Vue, React, Svelte, and Solid as UI layer options. Governed by the OpenJS Foundation and maintained by a global open-source community, it targets web developers who want native mobile performance without learning Swift or Kotlin.

Tauri is a Rust-and-WebView framework that lets developers ship cross-platform desktop and mobile applications from a single web-technology codebase. By leveraging the OS's native WebView rather than bundling a full browser, it produces dramatically smaller, faster, and more memory-efficient apps than Electron, with a security-first permission architecture that denies all native API access by default.

.NET MAUI (Multi-platform App UI) is Microsoft's open-source, cross-platform application framework for building native mobile and desktop apps from a single C# codebase, targeting Android, iOS, macOS, and Windows. It is the direct successor to the now-retired Xamarin.Forms platform.
