## What it is
SpectorJS is a JavaScript framework and browser extension for capturing and inspecting WebGL/WebGL2 frames. It lets developers view the full command list, visual states, shader sources, and context information for any WebGL engine or vanilla script.

## Use cases
- debug webgl rendering issues in my scene
- capture and inspect webgl frames
- see what draw calls a webgl app makes
- inspect shaders and visual state in webgl2
- troubleshoot 3d rendering in the browser
- debug webgl context without changing engine code

## When to choose
- you need engine-agnostic WebGL/WebGL2 frame debugging
- you want a browser extension or embeddable capture library
- you need to inspect draw calls, shaders, and textures in browser 3D apps

## When to avoid
- you need GPU-level profiling or performance counters rather than API call inspection
- you are debugging native OpenGL/Vulkan rather than WebGL

## Facets
- artifact type: library
- maturity: active
- function: developer-tools, graphics
- domain: web-development, graphics, developer-tools
- platform: browser, browser-extension
- tags: webgl, webgl2, debugger, inspector, frame-capture, shader-debugging, 3d, debugging, web-server
