If you know which requests you need to do in order to get the info you want instead of waiting for the headless browser to execute the javascript code that renders the needed data, it is pretty simple, you just need an http client and something to parse the content, depending if is html I'd recommend using cheerio in NodeJS to parse and traverse the content with a jQuery like API. If you must scrape the content with a headless browser, I'd choose Selenium. https://github.com/sourcegraph/go-selenium https://github.com/sourcegraph/go-selenium
