  Wow, that's a great idea! My idea was to create browser-less environment, so I can use it via https://www.npmjs.com/package/@unbuilt/cli https://www.npmjs.com/package/@unbuilt/cli or just API not loading users resources. I'm not actually spending funds, just because I built infra on DO droplets, so worth case scenario - people will wait a bit longer if no cache found and queue is too long. My question - how can I access iframe runtime of 3-rd party website and access window, or intercept requests to analyze better. For example, I check headers, check global vars, go to check source maps, etc. Having full control gives me a bit more flexibility to have the most confident analysis.

    Welcome! So what I did was have setup a proxy server in cloudflare workers. proxy.yourdomain.com?url=websitetocrawl Now in the worker, I replaced all the external resources of a html (CSS URLs, scripts) via regex to also go through the proxy. Since the proxy is under the same cross-origin you're able to do whatever you want. And even if it was a different domain, window.postMessage has a domain argument that allows you communicate explicitly with the parent window.
