WebGL inspect images in samplers (similar to Renderdoc)?

Question

Is there a debugging tool in any browser, as an extension or otherwise, or any tool, that I could use to visualize the image loaded into a 2d sampler in GLSL?

Essentially something that has the same functionality as renderdoc but for WebGL.

Answer 1

Spector.js can show textures bound to texture units and a ton of other useful for debugging information.
