Preventing Puppeteer Detection

Preventing-Puppeteer-Detection.md

I’m looking for any tips or tricks for making chrome headless mode less detectable. Here is what I’ve done so far:

Set my args as follows:

const run = (async () => {

    const args = [
        '--no-sandbox',
        '--disable-setuid-sandbox',
        '--disable-infobars',
        '--window-position=0,0',
        '--ignore-certifcate-errors',
        '--ignore-certifcate-errors-spki-list',
        '--user-agent="Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/65.0.3312.0 Safari/537.36"'
    ];

    const options = {
        args,
        headless: true,
        ignoreHTTPSErrors: true,
        userDataDir: './tmp'
    };

    const browser = await puppeteer.launch(options);

I’m loading in a preload file that overrides some window.navigator globals:

    const preloadFile = fs.readFileSync('./preload.js', 'utf8');
    await page.evaluateOnNewDocument(preloadFile);

preload.js

// overwrite the `languages` property to use a custom getter
Object.defineProperty(navigator, "languages", {
  get: function() {
    return ["en-US", "en"];
  };
});

// overwrite the `plugins` property to use a custom getter
Object.defineProperty(navigator, 'plugins', {
  get: function() {
    // this just needs to have `length > 0`, but we could mock the plugins too
    return [1, 2, 3, 4, 5];
  },
});

I see there are some other things suggested here https://intoli.com/blog/making-chrome-headless-undetectable/ but I'm not 100% certain how to implement them in puppeteer. Any ideas tips or tricks?

Works on localhost for me, fails on remote vps
