# Headless mode
|
||
|
|
|
||
|
|
By default Puppeteer launches the browser in
|
||
|
|
[the Headless mode](https://developer.chrome.com/docs/chromium/new-headless/).
|
||
|
|
|
||
|
|
```ts
|
||
|
|
const browser = await puppeteer.launch();
|
||
|
|
// Equivalent to
|
||
|
|
const browser = await puppeteer.launch({headless: true});
|
||
|
|
```
|
||
|
|
|
||
|
|
Before v22, Puppeteer launched the [old Headless mode](https://developer.chrome.com/docs/chromium/new-headless/) by default.
|
||
|
|
The old headless mode is now known as
|
||
|
|
[`chrome-headless-shell`](https://developer.chrome.com/blog/chrome-headless-shell)
|
||
|
|
and ships as a separate binary. `chrome-headless-shell` does not match the
|
||
|
|
behavior of the regular Chrome completely but it is currently more performant
|
||
|
|
for automation tasks where the complete Chrome feature set is not needed. If the performance
|
||
|
|
is more important for your use case, switch to `chrome-headless-shell` as following:
|
||
|
|
|
||
|
|
```ts
|
||
|
|
const browser = await puppeteer.launch({headless: 'shell'});
|
||
|
|
```
|
||
|
|
|
||
|
|
To launch a "headful" version of Chrome, set the
|
||
|
|
[`headless`](https://pptr.dev/api/puppeteer.browserlaunchargumentoptions) to `false`
|
||
|
|
option when launching a browser:
|
||
|
|
|
||
|
|
```ts
|
||
|
|
const browser = await puppeteer.launch({headless: false});
|
||
|
|
```
