Feature description

Can puppeteer launch headless browser and headed browser at the same time？

[OrKoN]

You can launch two browser instances by calling the launch method twice.

Howerver, when a headless browser launched, I cannot launch a headed browser any more.

[OrKoN]

import puppeteer from 'puppeteer'

const browser1 = await puppeteer.launch();
const browser2 = await puppeteer.launch({
  headless: false,
});

console.log('Two browsers launched');

browser1.close();
browser2.close();

works for me.

Oh, sorry、、I am using puppeteer-core and chrome、、

It would not work if you try to use the same userDataDir for example. Without seeing code, it is hard to say. Consider filing out a bug report form, if you think something is not working.

My codes below。I must use the same userDataDir to share user data for all browsers

    async openHeadless(){
        let  browser = await puppeteer.launch({
            width: screen.getPrimaryDisplay().width,
            height: screen.getPrimaryDisplay().height,
            executablePath: store.chromExecutablePath,
            headless: true,
            debuggingPort: remote_debugging_port,
            args: ['--remote-debugging-port=' + remote_debugging_port],
            ignoreDefaultArgs: ['--enable-automation'],
            userDataDir: 'default',
            defaultViewport: null,
        })
        let page = await browser.newPage()
        await page.goto('https://weibo.com')
        console.log('openHeadless success')
    },
    async openHeaded(){
        let  browser = await puppeteer.launch({
            width: screen.getPrimaryDisplay().width,
            height: screen.getPrimaryDisplay().height,
            executablePath: store.chromExecutablePath,
            headless: false,
            debuggingPort: remote_debugging_port,
            args: ['--remote-debugging-port=' + remote_debugging_port],
            ignoreDefaultArgs: ['--enable-automation'],
            userDataDir: 'default',
            defaultViewport: null,
        })
        let page = await browser.newPage()
        await page.goto('https://weibo.com')
        console.log('openHeaded success')
    }

That will not work since the instances can corrupt the user data dir. I suggest you make a copy for each of the instances.

Ok，thanks a lot
