Live App Architecture Debugging with Kotzilla & Koin
summary
Live demos use the Now in Android sample migrated to Koin plus a JetBrains Koin plugin and the Codzilla Kotzilla platform to capture real user sessions, show a 1.5s artificial delay, and flag viewmodel creation taking >500 ms and component resolutions over 100 ms. The tooling shows a 41-instance dependency graph, background-thread blocking, startup >6s (threshold 5s), memory allocation per object (1–60 ms), and generates AI prompts to propose fixes; the plugin and cloud console work but demos suffer intermittent Wi‑Fi hiccups.
