Android Developer’s Kotlin Stack — Ktor, Koin, Coil & SQLDelight
Hey Android developers! 👋 Have you heard of Ktor, Koin, Coil, or SQLDelight yet?
If not, you’re missing out on some of the cleanest and most modern tools in the Kotlin ecosystem.
If you’re building Android apps , it’s time to move beyond the old Retrofit + Dagger + Room combo.
The modern Kotlin ecosystem gives us something cleaner, faster, and 100% coroutine-friendly.

🌐 Ktor
A modern, coroutine-based HTTP client.
Fetch APIs and network data asynchronously using coroutines. It’s lightweight, Kotlin-first, and multiplatform-ready, making networking simpler than ever.
💉 Koin
Lightweight dependency injection made easy.
Forget complex Dagger setups — Koin lets you inject your repositories, ViewModels, and services with simple Kotlin DSL, keeping your code clean and testable.
💾 SQLDelight
Type-safe, compile-time verified database.
SQLDelight generates Kotlin classes from your .sq files. Queries are checked at compile time, giving you safer and faster database access than raw SQLite
🖼️ Coil
Kotlin-first image loader with Compose support.
Load images from the web, files, or resources efficiently with full coroutine support. Perfect for Jetpack Compose apps, with caching and transformations built-in.
Why This Stack is Awesome
- ⚡ Clean Architecture — Each library has a clear role, keeping your code organized and maintainable.
- 🧵 Full Kotlin Support — Everything is coroutine-friendly and type-safe.
- ✨ Zero Boilerplate — Forget Dagger annotations or manual SQLite queries.
- 🖥 Compose Ready — Coil integrates seamlessly with Jetpack Compose; Koin works with ViewModels.
- 💾 Reliable Data — SQLDelight ensures compile-time verified queries, reducing runtime bugs.
Together, they give you a modern, scalable, and efficient Android foundation — perfect for building apps faster, cleaner, and more reliably.
👉🏻 Next Steps
Want to see this stack in action? In the next blog, we’ll build a working Android app that:
- Fetches data from an API using Ktor
- Stores it safely with SQLDelight
- Loads images smoothly using Coil
- Uses Koin to wire everything together cleanly
💡 Pro tip: Setting up all these libraries and wiring them together can take a bit of time, so having a ready-to-run GitHub project will make it much easier. I’ll share the project link along with the next post …
Stay tuned to learn how to go from setup to a fully functional, modern Kotlin Android app — all without boilerplate! 🚀
Thank you for reading! 🙂
