I'd love to know if puppeteer passed that test (probably). I have had exactly this problem many, many times and it is incredibly frustrating.

puppeteer passes the test if you run it from a machine that already has a good cloudflare reputation score. Try it from an AWS instance and it definitely fails 100% of the time.

(I've tried it, that's how I know)

There are github projects that are forks of things like selenium and puppeteer that are specifically designed to avoid detection for things like scraping google search results, etc.

That's fine as processing the javascript increases the coast at-least.
