Kotzilla

Kotzilla is a mobile application observability and AI remediation platform that helps Android and Kotlin Multiplatform (KMP) development teams identify, diagnose, and resolve production issues faster. Built on top of Koin, the #1 dependency injection framework for Android, Kotzilla automatically captures runtime data at the architecture level, giving developers the structural context needed to understand not just what broke, but why. Unlike general-purpose APM tools that require manual instrumentation, Kotzilla leverages Koin's embedded dependency graph to map component lifecycles and relationships automatically. This architecture-level intelligence makes AI-assisted fixes accurate and targeted, providing an unique context and knowledge base to LLM to ensure reliable fixes, even for complex issues. Kotzilla supports Android and KMP projects, with a single SDK for multiple targets: Android, iOS, Desktop (JVM), and Web (JS/WASM). Observability capabilities: -Crash & ANR tracking automatically captures unhandled exceptions, application-not-responding events, and startup failures, grouping them with session context and architecture-level data to surface root causes quickly -Session timeline provides a graphical, real-time view of user sessions, showing the sequence of events, component interactions, and failures leading up to an issue, without requiring manual log correlation -Dependency graph visualization automatically maps the application's Koin dependency graph and component lifecycles, making it immediately clear which modules, services, or injected dependencies are implicated in a given failure -Startup performance monitoring tracks app initialization metrics to detect regressions in boot time, slow module loading, and initialization order issues Fix your production issues in minutes instead of hours: -Kotzilla MCP connects production runtime data directly to the developer's IDE or terminal via the Model Context Protocol, enabling AI-assisted debugging with full application context, not just a stack trace -Koin Knowledge Base provides expert remediation guidance specific to Koin-based architectures, improving the accuracy and relevance of suggested fixes -IDE plugin surfaces performance reports and issue context inside the development environment, reducing context switching and time to resolution Deployment and integration: Developers integrate Kotzilla by adding the lightweight SDK to their existing Koin setup. Instrumentation is automatic; no manual trace configuration or annotation is required, holistic view of the application granted. The Kotzilla Console provides a web-based dashboard for monitoring app health, visualizing session timelines, and sharing diagnostic reports across teams. Kotzilla is designed for mobile and KMP development teams looking to reduce monitoring overhead and accelerate issue resolution. The platform reports a 50% reduction in monitoring costs through focused runtime data capture, and a 90% reduction in time to fix when using the Kotzilla MCP integration.
