Show HN: I made a Chrome extension that can automate any website

As a web scraper, I'll say that because he is hooking into the browser like a debugger / remotely controlled browser, just like Puppeteer would - he is instantly detected by the Cloudflare, PerimeterX, Datadome bot management solutions; and will get consistently banned on his page reload for literally any site caring about bots.

He'd be better off running some javascript on the page instead (a-la Tampermonkey, but can be done really nicely with some server-served TypeScript) to scrape the pages stealthily and perform actions.

Run it against https://bot.sannysoft.com/ to see how it stacks up

Most anti-Puppeteer tech analyzes the state of various browser Javascript objects, and if you run Puppeteer in headful mode with plugins like https://www.npmjs.com/package/puppeteer-extra-plugin-stealth you'll bypass most detection.
