About this extension
This DevTools extension is designed specifically for Opus UI applications, offering powerful insight into your app’s structure and runtime state. Whether you're building dashboards, flows, or complex interfaces, this tool helps you understand what’s going on under the hood.
With this extension, you can:
🔍 Inspect Components: Easily find components by ID, type, or scope.
🧠 View Application State: Access and explore live state with clear visual structure.
🔄 Trace Flows: See how data and actions move through flows and scopes.
🧭 Navigate Hierarchies: Understand relative IDs and how components relate to each other.
⚡ Debug Faster: A focused interface built for productivity and clarity, unlike general-purpose tools.
Built as a replacement for React DevTools, this extension speaks Opus natively — no translation layer needed, no clutter.
