Why use Compose Multiplatform for web

Build faster, share sooner

Bring your ideas to life instantly. Share new features or prototypes through a simple web link – no APKs, no builds, and no waiting.

Use your Compose skills everywhere

Keep using the APIs, patterns, and workflows you’re familiar with. Move from Android Studio straight to the browser.

Extend your app, don’t rebuild it

Reuse your logic, components, and architecture across Android, desktop, and the web. One Kotlin codebase powers many screens.

Deliver high-quality UIs in the browser

Create smooth animations and responsive layouts – all rendered in the browser.

Write pure Kotlin with zero JavaScript required

Skip JS toolchains and complex configuration. Stay in Kotlin, build with Gradle, and deploy directly to the web in a familiar workflow.

“I use Compose Multiplatform for web to showcase the components and APIs in my Compose Multiplatform open-source library. People love the interactive demos in the documentation. I believe it helped with the adoption of open source a lot, instead of using static images.”

“exaBase Roleplay is a Kotlin-based, enterprise-grade AI tool for voice-to-voice sales training, used by top financial institutions in Japan. It’s powered by Ktor and Compose Multiplatform for web (Wasm), which has been running in production for over a year – well before Compose Multiplatform for web reached Alpha. The app is live on iOS, Android, and the web with 90% shared code.”

“I built a management app for our football club – fully in KMP.
Some of our functionaries mainly use their work laptops, where installing third-party software isn’t always possible.
For that, Compose Multiplatform for web is a great alternative that can be set up and published quickly.”

“I introduced Compose Multiplatform at my company to showcase our design system in the browser. What’s really cool is that people started using it even on branches to show changes that could then be reviewed by stakeholders who only have iOS devices – right in their browsers.”

““I used Compose Multiplatform for web to build artistalley.pages.dev, which let me – a purely Android developer – reach a much wider audience at conventions, including iOS and Mac users. I don’t have exact numbers, but we went from fewer than 10,000 users last year with the original Google Sheets/Android setup to around 100,000 this year with the website. I credit a lot of that growth to the accessibility of a website compared to a spreadsheet or an Android-only app.”
