Kotlin Multiplatform: Android, iOS, Desktop & Web - One Codebase

Why Your Competitors Are Shipping 2x Faster

They're building once, deploying everywhere. You're still maintaining separate codebases.

Kotlin Multiplatform lets you write your business logic once and deploy it to Android, iOS, Desktop, and Web - all from a single codebase. While you're fixing the same bug three times, they've already shipped their next feature.

60-90% Code Reuse
100% Native Performance
5+ Platforms Supported

We deliver production-ready apps with shared business logic and platform-specific UI

✓ Faster Time to Market

We help you launch on all platforms simultaneously without maintaining separate codebases

✓ Lower Development Costs

We reduce your development and maintenance costs by up to 60% with code sharing

Technical Benefits & Features

Maximum Code Reuse

Share business logic, networking, data persistence, and algorithms across platforms. Typically achieve 60-90% code sharing depending on project requirements.

Native Performance

Compiles to native code on each platform. No overhead from interpreters or virtual machines - your code runs at full native speed.

Platform-Specific APIs

Use expect/actual declarations to access platform-specific features while maintaining shared code. Full access to iOS, Android, and platform-specific capabilities.

Interoperability

Seamlessly integrate with existing Swift/Objective-C (iOS) and Java/Kotlin (Android) codebases. Adopt gradually without full rewrites.

Type Safety

Kotlin's strong type system catches errors at compile time, reducing runtime crashes and improving code quality across all platforms.

Modern Tooling

Full IDE support in Android Studio and IntelliJ IDEA with debugging, refactoring, and code completion across platforms.

Use Cases & Examples

Mobile Applications

Build iOS and Android apps sharing business logic, API clients, data models, and validation while using native UI frameworks (SwiftUI/Jetpack Compose or Compose Multiplatform for fully shared UI).

Cross-Platform Desktop Apps

Create desktop applications for Windows, macOS, and Linux using Compose Multiplatform, sharing code with your mobile applications.

Backend & Frontend Sharing

Share data models, validation logic, and business rules between Kotlin backend services (Ktor, Spring) and multiplatform clients.

SDK Development

Create libraries and SDKs that work across multiple platforms from a single codebase - perfect for analytics, networking, or utility libraries.
