Puppeteer Launch Incognito

Question

I am connected to a browser using a ws endpoint (puppeteer.connect({ browserWSEndpoint: '' })).

When I launch the browser that I ultimately connect to, is there a way to launch this in incognito?

I know I can do something like this:

const incognito = await this.browser.createIncognitoBrowserContext();

But it seems like the incognito session is tied to the originally opened browser. I just want it to be by itself.

I also see you can do this:

const baseOptions: LaunchOptions = { args: ['--incognito']};

But I am not sure if this is the best way or not.

Any advice would be appreciated. Thank you!

The best way to accomplish your goal is to launch the browser directly into incognito mode by passing the --incognito flag to puppeteer.launch():

const browser = await puppeteer.launch({
  args: [
    '--incognito',
  ],
});

Alternatively, you can create a new incognito browser context after launching the browser using browser.createIncognitoBrowserContext():

const browser = await puppeteer.launch();
const context = await browser.createIncognitoBrowserContext();

You can check whether a browser context is incognito using browserContext.isIncognito():

if (context.isIncognito()) { /* ... */ }
