Command Line Interface

Playwright comes with the command line tools.


# Install the CLI once.
dotnet tool install --global Microsoft.Playwright.CLI
# Use the tools.

Generate code#

playwright codegen

Run codegen and perform actions in the browser. Playwright CLI will generate JavaScript code for the user interactions. codegen will attempt to generate resilient text-based selectors.

Preserve authenticated state#

Run codegen with --save-storage to save cookies and localStorage at the end. This is useful to separately record authentication step and reuse it later.

playwright codegen --save-storage=auth.json
# Perform authentication and exit.
# auth.json will contain the storage state.

Run with --load-storage to consume previously loaded storage. This way, all cookies and localStorage will be restored, bringing most web apps to the authenticated state.

playwright open --load-storage=auth.json
playwright codegen --load-storage=auth.json
# Perform actions in authenticated state.

Codegen with custom setup#

If you would like to use codegen in some non-standard setup (for example, use BrowserContext.RouteAsync(url, handler)), it is possible to call Page.PauseAsync() that will open a separate window with codegen controls.

using Microsoft.Playwright;
using System.Threading.Tasks;
class Program
public static async Task Main()
using var playwright = await Playwright.CreateAsync();
var chromium = playwright.Chromium;
// Make sure to run headed.
var browser = await chromium.LaunchAsync(new BrowserTypeLaunchOptions { Headless = false });
// Setup context however you like.
var context = await browser.NewContextAsync(); // Pass any options
await context.RouteAsync('**/*', route => route.ContinueAsync());
// Pause the page, and start recording manually.
var page = await context.NewPageAsync();
await page.PauseAsync();

Open pages#

With open, you can use Playwright bundled browsers to browse web pages. Playwright provides cross-platform WebKit builds that can be used to reproduce Safari rendering across Windows, Linux and macOS.

# Open page in Chromium
playwright open
# Open page in WebKit
playwright wk

Emulate devices#

open can emulate mobile and tablet devices from the playwright.devices list.

# Emulate iPhone 11.
playwright open --device="iPhone 11"

Emulate color scheme and viewport size#

# Emulate screen size and color scheme.
playwright open --viewport-size=800,600 --color-scheme=dark

Emulate geolocation, language and timezone#

# Emulate timezone, language & location
# Once page opens, click the "my location" button to see geolocation in action
playwright open --timezone="Europe/Rome" --geolocation="41.890221,12.492348" --lang="it-IT"

Inspect selectors#

During open or codegen, you can use following API inside the developer tools console of any browser.


Query Playwright selector, using the actual Playwright query engine, for example:


Same as playwright.$, but returns all matching elements.


Reveal element in the Elements panel (if DevTools of the respective browser supports it).


Generates selector for the given element.

Take screenshot#

# Wait 3 seconds before capturing a screenshot after page loads ('load' event fires)
playwright screenshot \
--device="iPhone 11" \
--color-scheme=dark \
--wait-for-timeout=3000 \ twitter-iphone.png
# Capture a full page screenshot
playwright screenshot --full-page wiki-full.png

Generate PDF#

PDF generation only works in Headless Chromium.

# See command help
playwright pdf wiki.pdf

Install system dependencies#

Ubuntu 18.04 and Ubuntu 20.04 system dependencies can get installed automatically. This is useful for CI environments.

# See command help
playwright install-deps

You can also install the dependencies for a single browser only by passing it as an argument:

playwright install-deps chromium

Known limitations#

Opening WebKit Web Inspector will disconnect Playwright from the browser. In such cases, code generation will stop.
