Open Source at Aetherius
Tools, libraries, templates, and experiments built by our
senior engineering team.
Shared to help others
Instead of solving the same problem repeatedly, we turn useful parts of our work into reusable tools, templates, libraries, and examples that other developers can build on.
Aetherius KMP Starter
Production-ready foundation for building Kotlin Multiplatform applications.
A starter project containing the architecture, integrations, and patterns we commonly use when starting production KMP applications.
CMP Native Navigation
Use shared Compose UI without sacrificing native iOS navigation.
Example implementation showing how Compose screens can work together with native navigation patterns on Android and iOS.

Aetherius KMP Starter
Production-ready foundation for building Kotlin Multiplatform applications.
The Problem
As useful as KMP setup is once it’s done correctly, it takes a lot of time and boilerplate code to initially make it work. There is always a struggle in finding solutions that work for both platforms, and bridging gaps for parts that still don’t exist.
Why We Built It
Our team also fell victim to initial KMP setup the first time we started using KMP. Many libraries were still in alpha or beta and we struggled a lot to patch differences between platforms, resulting in many hours spent on research and rewriting the code. Once we went through the fire ourselves, we wanted to make the whole process easier for anybody starting the KMP from scratch.

- Runnable iOS and Android app
Built With
Built in Kotlin for shared business logic and Android UI, and Swift for iOS UI, while relying on standard Firebase libraries for Sign in, Database, and Storage. Uses Koin for dependency injection and Ktor for API calls
