Is Kotlin Multiplatform production ready in 2026?

TL;DR: Yes. Kotlin Multiplatform has been stable since November 2023, Compose Multiplatform for iOS reached stable in May 2025, and companies like Netflix, McDonald's, and Cash App have been running KMP in production for years. The question is no longer if KMP is production ready, but how to adopt it effectively.

The short answer

Kotlin Multiplatform is production ready. JetBrains declared KMP stable in November 2023, and Google officially recommends it for sharing business logic between Android and iOS. As of 2025, Compose Multiplatform for iOS also reached stable status with version 1.8.0, meaning you can now share UI code across platforms with full production support.

But "production ready" means different things to different teams. Let's look at what's actually stable, what's still maturing, and what real companies are doing with KMP today.

What's stable in 2026

Kotlin Multiplatform core

The core KMP framework for sharing business logic (networking, data models, validation, business rules) has been stable since late 2023. This is the most battle-tested part of the ecosystem.

Compose Multiplatform for iOS

As of May 2025, Compose Multiplatform for iOS is officially stable. This means you can share UI code between Android and iOS with production-level support. The release includes native-like scrolling, iOS-native text selection, drag-and-drop functionality, variable font support, and natural gestures.

Android integration

Google officially supports KMP for Android development. Jetpack libraries like Room 2.8.3, DataStore 1.1.7, and ViewModel 2.9.4 now work with Kotlin Multiplatform, allowing you to use familiar Android APIs in your shared code.

Swift export (experimental but improving)

Kotlin 2.2.20 introduced direct Swift export, eliminating the need for Objective-C bridging. While still experimental, JetBrains is targeting stable Swift interoperability in 2026.

What's still maturing

Compose Multiplatform for web

The web target is currently in Beta. JetBrains continues to improve performance and add web implementations for more APIs. It's usable for early adopters but not yet at the same stability level as iOS and Android.

Kotlin/Wasm

WebAssembly support is progressing toward Beta. For web targets, Kotlin/JS remains the more stable option for now, with Wasm offering better performance for compute-heavy applications.

Companies running KMP in production

The best proof of production readiness is real-world usage. Here are three companies that have bet heavily on KMP:

Netflix

Netflix became the first FAANG company to publicly adopt KMP in 2020. They use it for their Prodicle app, which supports physical production of TV shows and movies. The app handles complex calculations on-device due to poor connectivity on film sets, making shared business logic essential.

McDonald's

McDonald's processes 6.5 million monthly purchases through their KMP-powered app, serving 69 million daily customers. After initial success with payments, they expanded KMP across their entire application. The result: fewer crashes and better performance on both platforms.

Cash App

Cash App has run KMP in production since 2018, making them one of the longest-running KMP adopters. As the #1 financial app in the United States, they handle critical financial transactions with KMP-powered shared code. Their engineering team has also contributed numerous open-source KMP libraries to the community.

Key statistics

Metric	Value
Market share growth	12% to 23% (2023-2025)
Developer reach	2.5 million developers worldwide
Code sharing	80%+ between platforms
Production track record	Cash App: 7+ years

When KMP might not be right for you

Production ready doesn't mean right for every project. Consider alternatives if:

Your team has no Kotlin experience and tight deadlines. The learning curve is real.
You need heavy platform-specific UI with minimal shared logic. The overhead may not be worth it.
Your iOS team strongly prefers native Swift. KMP works best when both platform teams buy in.

How to adopt KMP in 2026

The pattern every successful company follows:

Start with shared business logic. Networking, data models, validation, and business rules are the safest starting point.
Keep UI native initially. Let your teams stay productive while the shared layer proves itself.
Consider shared UI later. Once Compose Multiplatform fits your needs, you can share UI incrementally.
Use production-ready tooling. Don't reinvent the wheel for auth, payments, analytics, and CI/CD.

Skip the setup, start building

If you want to skip the months of infrastructure setup and start with a production-ready foundation, KMPShip gives you authentication, payments, CI/CD, and more out of the box, so you can focus on building your actual app.

The bottom line

Kotlin Multiplatform in 2026 is not experimental. It's not a gamble. It's a mature technology backed by JetBrains, endorsed by Google, and proven by companies processing millions of transactions.

The real question isn't whether KMP is production ready. It's whether your team is ready to take advantage of it.
