Technically - for hierarchy / rendering, [Spector.js](https://github.com/BabylonJS/Spector.js) may be able to help you.  
For performance and CPU/GPU load inspection - [stats.gl](https://github.com/RenaudRohlinger/stats-gl).  
For RTs - [RenderTargetInspector](https://github.com/Fyrestar/THREE.RenderTargetInspector).  
For Unreal-like material cost inspection - [DrawCallInspector](https://github.com/Fyrestar/THREE.DrawCallInspector).
