SpectorJS is kind of abandoned nowadays, it hardly has changed and doesn't support WebGPU.

Running the whole browser rendering stack is a masochist exercise, I rather re-code the algorithm in native code, or go back into pixel debugging.

I would vouch the state of bad tooling, and how browsers blacklist users systems, is a big reason studios rather try out streaming instead of rendering on the browser.

yeah... I tired to extend Spectors ui, the code base is "interesting" for simple changes seemed way harder than it should have been. Shame though as its really the only tool like it for web.

My favourite though is safari, graphics driver crashes all the time, the dev tools normally crash as well, so you have zero idea what is happening.

And I've found when the graphics crash the whole browsers graphic state become unreliable until you force close safari and reopen.
