We're Kotzilla — and We're Done Watching Android Devs Navigate Blind

Hey dev.to 👋
We're the team behind Koin — the dependency injection framework used by 25% of native Android applications. If you've built an Android or Kotlin Multiplatform app in the last few years, there's a good chance Koin is already in your stack.
We've spent years in the Android ecosystem. We know the codebase, the tooling, the pain points. And one pain point kept coming up, over and over again:

Production issues you can't explain.
A crash you can't reproduce. A frozen screen that only happens at scale. A startup time that degrades release after release, with no clear culprit. Most monitoring tools give you flat signals, logs, and stack traces and leave you to do the correlation manually.
We got tired of watching great developers navigate blind.

So we built Kotzilla
Kotzilla is a runtime observability platform built specifically for Android and Kotlin Multiplatform apps. Not a generic APM with a mobile SDK bolted on. Built from the ground up for the Kotlin ecosystem, with deep integration into the dependency injection layer where most performance issues actually originate.
The platform captures every event with full structural context: which component, which thread, which scope, which screen. It doesn't just tell you something is slow. It tells you why — and points to the exact component responsible.

What we just shipped: Console 4.0
Today we're sharing a walkthrough of our new Dashboard,the centrepiece of Console 4.0.

It connects business-level health KPIs (Crash Free Rate, ANR Free Rate, Slow Component Free Rate) to the root cause detection Kotzilla is known for. You start from user impact, drill down to the blocking component, and land on the exact dependency resolution causing the problem,in three clicks, with no custom instrumentation.
We walk through a real example in the full article, from a slow MainActivity all the way to MainViewModel, blocking the main thread and the full dependency graph explaining why.

What's next
We'll be posting here regularly — deep dives on Android performance, Kotlin Multiplatform observability, Koin internals, and everything we're learning building dev tools in the open.
If that sounds useful, follow us. And if you have questions, war stories about production issues, or things you wish your observability tooling could do — drop them in the comments. We're genuinely listening.
