# Kotzilla Platform Documentation

> AI-native developer observability platform for Android and Kotlin Multiplatform (KMP) apps. Kotzilla captures runtime data at the architecture level (dependency graphs, component lifecycles, scopes, threads) and connects it to any AI coding assistant through the Kotzilla MCP Server, so AI fixes are accurate instead of generic. It works on any Android or KMP app, with Koin, Hilt, Metro, Dagger or manual dependency injection.

Coding agents read your source code but they never see your production runtime. That is why an AI assistant can describe an ANR but cannot tell you which component chain caused it on a real user device. Kotzilla closes that gap for Android and Kotlin Multiplatform teams.

Kotzilla is built by the team behind Koin, the #1 dependency injection framework for Android, used by 40% of native Android apps with 20M+ monthly downloads across 130 countries. Because Koin instruments the application container, Kotzilla collects component resolution, dependency graphs, scopes and lifecycle data automatically, with no manual traces to add. Since SDK 2.3.0, the Kotzilla SDK also runs on apps with no Koin container at all: Hilt, Metro, Dagger or manual DI.

Traditional APMs collect logs and metrics. Kotzilla collects architecture, which is the context an AI agent needs to produce a one-shot fix.

This site is the Kotzilla Platform documentation: SDK setup for Android, KMP, CMP and non-Koin projects, issue detection and fixes, the Kotzilla Console, the Koin IDE Plugin, and the Kotzilla MCP Server.
