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
