## Introduction

Each version of Playwright needs specific versions of browser binaries to operate. You will need to use the Playwright CLI to install these browsers.

With every release, Playwright updates the versions of the browsers it supports, so that the latest Playwright would support the latest browsers at any moment. It means that every time you update Playwright, you might need to re-run the `install` CLI command.

## Install browsers

Playwright can install supported browsers. Running the command without arguments will install the default browsers.

```bash js
npx playwright install
```

```bash java
mvn exec:java -e -D exec.mainClass=com.microsoft.playwright.CLI -D exec.args="install"
```

```bash python
playwright install
```

```bash csharp
pwsh bin/Debug/netX/playwright.ps1 install
```

You can also install specific browsers by providing an argument:

```bash js
npx playwright install webkit
```

```bash java
mvn exec:java -e -D exec.mainClass=com.microsoft.playwright.CLI -D exec.args="install webkit"
```

```bash python
playwright install webkit
```

```bash csharp
pwsh bin/Debug/netX/playwright.ps1 install webkit
```

See all supported browsers:

```bash js
npx playwright install --help
```

```bash java
mvn exec:java -e -D exec.mainClass=com.microsoft.playwright.CLI -D exec.args="install --help"
```

```bash python
playwright install --help
```

```bash csharp
pwsh bin/Debug/netX/playwright.ps1 install --help
```

### Install browsers via API
* langs: csharp

It's possible to run Command line tools commands via the .NET API:

```csharp
var exitCode = Microsoft.Playwright.Program.Main(new[] {"install"});
if (exitCode != 0)
{
    throw new Exception($"Playwright exited with code {exitCode}");
}
```

## Install system dependencies

System dependencies can get installed automatically. This is useful for CI environments.

```bash js
npx playwright install-deps
```

```bash java
mvn exec:java -e -D exec.mainClass=com.microsoft.playwright.CLI -D exec.args="install-deps"
```

```bash python
playwright install-deps
```

```bash csharp
pwsh bin/Debug/netX/playwright.ps1 install-deps
```

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

```bash js
npx playwright install-deps chromium
```

```bash java
mvn exec:java -e -D exec.mainClass=com.microsoft.playwright.CLI -D exec.args="install-deps chromium"
```

```bash python
playwright install-deps chromium
```

```bash csharp
pwsh bin/Debug/netX/playwright.ps1 install-deps chromium
```

It's also possible to combine `install-deps` with `install` so that the browsers and OS dependencies are installed with a single command.

```bash js
npx playwright install --with-deps chromium
```

```bash java
mvn exec:java -e -D exec.mainClass=com.microsoft.playwright.CLI -D exec.args="install --with-deps chromium"
```

```bash python
playwright install --with-deps chromium
```

```bash csharp
pwsh bin/Debug/netX/playwright.ps1 install --with-deps chromium
```

See [system requirements](./intro.md#system-requirements) for officially supported operating systems.

## Update Playwright regularly
* langs: js

By keeping your Playwright version up to date you will be able to use new features and test your app on the latest browser versions and catch failures before the latest browser version is released to the public.

```bash
# Update playwright
npm install -D @playwright/test@latest

# Install new browsers
npx playwright install
```
Check the [release notes](./release-notes.md) to see what the latest version is and what changes have been released.

```bash
# See what version of Playwright you have by running the following command
npx playwright --version
```

## Configure Browsers

Playwright can run tests on Chromium, WebKit and Firefox browsers as well as branded browsers such as Google Chrome and Microsoft Edge. It can also run on emulated tablet and mobile devices. See the [registry of device parameters](https://github.com/microsoft/playwright/blob/main/packages/playwright-core/src/server/deviceDescriptorsSource.json) for a complete list of selected desktop, tablet and mobile devices.

### Run tests on different browsers
* langs: js

Playwright can run your tests in multiple browsers and configurations by setting up **projects** in the config. You can also add [different options](./test-configuration) for each project.

```js
import { defineConfig, devices } from '@playwright/test';

export default defineConfig({
  projects: [
    /* Test against desktop browsers */
    {
      name: 'chromium',
      use: { ...devices['Desktop Chrome'] },
    },
    {
      name: 'firefox',
      use: { ...devices['Desktop Firefox'] },
    },
    {
      name: 'webkit',
      use: { ...devices['Desktop Safari'] },
    },
    /* Test against mobile viewports. */
    {
      name: 'Mobile Chrome',
      use: { ...devices['Pixel 5'] },
    },
    {
      name: 'Mobile Safari',
      use: { ...devices['iPhone 12'] },
    },
    /* Test against branded browsers. */
    {
      name: 'Google Chrome',
      use: { ...devices['Desktop Chrome'], channel: 'chrome' }, // or 'chrome-beta'
    },
    {
      name: 'Microsoft Edge',
      use: { ...devices['Desktop Edge'], channel: 'msedge' }, // or 'msedge-dev'
    },
  ],
});
```

Playwright will run all projects by default.

```bash
npx playwright test

Running 7 tests using 5 workers

  ✓ [chromium] › example.spec.ts:3:1 › basic test (2s)
  ✓ [firefox] › example.spec.ts:3:1 › basic test (2s)
  ✓ [webkit] › example.spec.ts:3:1 › basic test (2s)
  ✓ [Mobile Chrome] › example.spec.ts:3:1 › basic test (2s)
  ✓ [Mobile Safari] › example.spec.ts:3:1 › basic test (2s)
  ✓ [Google Chrome] › example.spec.ts:3:1 › basic test (2s)
  ✓ [Microsoft Edge] › example.spec.ts:3:1 › basic test (2s)
```

Use the `--project` command line option to run a single project.

```bash
npx playwright test --project=firefox

Running 1 test using 1 worker

  ✓ [firefox] › example.spec.ts:3:1 › basic test (2s)
```

With the VS Code extension you can run your tests on different browsers by checking the checkbox next to the browser name in the Playwright sidebar. These names are defined in your Playwright config file under the projects section. The default config when installing Playwright gives you 3 projects, Chromium, Firefox and WebKit. The first project is selected by default.

![Projects section in VS Code extension](https://github.com/microsoft/playwright/assets/13063165/58fedea6-a2b9-4942-b2c7-2f3d482210cf)

To run tests on multiple projects(browsers), select each project by checking the checkboxes next to the project name.

### Run tests on different browsers
* langs: python

Run tests on a specific browser:

```bash
pytest test_login.py --browser webkit
```

Run tests on multiple browsers:

```bash
pytest test_login.py --browser webkit --browser firefox
```

Test against mobile viewports:

```bash
pytest test_login.py --device="iPhone 13"
```
Test against branded browsers:

```bash
pytest test_login.py --browser-channel msedge
```

### Run tests on different browsers
* langs: java

Run tests on a specific browser:

```java
import com.microsoft.playwright.*;

public class Example {
  public static void main(String[] args) {
    try (Playwright playwright = Playwright.create()) {
      // Launch chromium, firefox or webkit.
      Browser browser = playwright.chromium().launch();
      Page page = browser.newPage();
      // ...
    }
  }
}
```

Run tests on multiple browsers and make it based on the environment variable `BROWSER`:

```java
import com.microsoft.playwright.*;

public class Example {
  public static void main(String[] args) {
    try (Playwright playwright = Playwright.create()) {
      Browser browser = null;
      String browserName = System.getenv("BROWSER");
      if (browserName.equals("chromium")) {
        browser = playwright.chromium().launch();
      } else if (browserName.equals("firefox")) {
        browser = playwright.firefox().launch();
      } else if (browserName.equals("webkit")) {
        browser = playwright.webkit().launch();
      }
      Page page = browser.newPage();
      // ...
    }
  }
}
```

### Run tests on different browsers
* langs: csharp

Run tests on a specific browser:

```bash
dotnet test -- Playwright.BrowserName=webkit
```

To run your test on multiple browsers or configurations you need to invoke the `dotnet test` command multiple times. You can either specify the `BROWSER` environment variable or set the `Playwright.BrowserName` via the runsettings file:

```bash
dotnet test --settings:chromium.runsettings
dotnet test --settings:firefox.runsettings
dotnet test --settings:webkit.runsettings
```

```xml
<?xml version="1.0" encoding="utf-8"?>
  <RunSettings>
    <Playwright>
      <BrowserName>chromium</BrowserName>
    </Playwright>
  </RunSettings>
```

### Chromium

For Google Chrome, Microsoft Edge and other Chromium-based browsers, by default, Playwright uses open source Chromium builds. Since the Chromium project is ahead of the branded browsers, when the world is on Google Chrome N, Playwright already supports Chromium N+1 that will be released in Google Chrome and Microsoft Edge a few weeks later.

Playwright ships a regular Chromium build for headed operations and a separate [chromium headless shell](https://developer.chrome.com/blog/chrome-headless-shell) for headless mode. See [issue #33566](https://github.com/microsoft/playwright/issues/33566) for details.

#### Optimize download size on CI

If you are only running tests in headless shell (i.e. the `channel` option is not specified), for example on CI, you can avoid downloading the full Chromium browser by passing `--only-shell` during installation.

```bash js
# only running tests headlessly
npx playwright install --with-deps --only-shell
```

```bash java
# only running tests headlessly
mvn exec:java -e -D exec.mainClass=com.microsoft.playwright.CLI -D exec.args="install --with-deps --only-shell"
```

```bash python
# only running tests headlessly
playwright install --with-deps --only-shell
```

```bash csharp
# only running tests headlessly
pwsh bin/Debug/netX/playwright.ps1 install --with-deps --only-shell
```

#### Opt-in to new headless mode

You can opt into the new headless mode by using `'chromium'` channel. As [official Chrome documentation puts it](https://developer.chrome.com/blog/chrome-headless-shell):

> New Headless on the other hand is the real Chrome browser, and is thus more authentic, reliable, and offers more features. This makes it more suitable for high-accuracy end-to-end web app testing or browser extension testing.

See [issue #33566](https://github.com/microsoft/playwright/issues/33566) for details.

```js
import { defineConfig, devices } from '@playwright/test';

export default defineConfig({
  projects: [
    {
      name: 'chromium',
      use: { ...devices['Desktop Chrome'], channel: 'chromium' },
    },
  ],
});
```

```java
import com.microsoft.playwright.*;

public class Example {
  public static void main(String[] args) {
    try (Playwright playwright = Playwright.create()) {
      Browser browser = playwright.chromium().launch(new BrowserType.LaunchOptions().setChannel("chromium"));
      Page page = browser.newPage();
      // ...
    }
  }
}
```

```bash python
pytest test_login.py --browser-channel chromium
```

```xml csharp
<?xml version="1.0" encoding="utf-8"?>
<RunSettings>
  <Playwright>
    <BrowserName>chromium</BrowserName>
    <LaunchOptions>
      <Channel>chromium</Channel>
    </LaunchOptions>
  </Playwright>
</RunSettings>
```

```bash csharp
dotnet test -- Playwright.BrowserName=chromium Playwright.LaunchOptions.Channel=chromium
```

### Google Chrome & Microsoft Edge

While Playwright can download and use the recent Chromium build, it can operate against the branded Google Chrome and Microsoft Edge browsers available on the machine (note that Playwright doesn't install them by default). In particular, the current Playwright version will support Stable and Beta channels of these browsers.

Available channels are `chrome`, `msedge`, `chrome-beta`, `msedge-beta`, `chrome-dev`, `msedge-dev`, `chrome-canary`, `msedge-canary`.

:::warning
Certain Enterprise Browser Policies may impact Playwright's ability to launch and control Google Chrome and Microsoft Edge. Running in an environment with browser policies is outside of the Playwright project's scope.
:::

:::warning
Google Chrome and Microsoft Edge have switched to a [new headless mode](https://developer.chrome.com/docs/chromium/headless) implementation that is closer to a regular headed mode. This differs from [chromium headless shell](https://developer.chrome.com/blog/chrome-headless-shell) that is used in Playwright by default when running headless, so expect different behavior in some cases. See [issue #33566](https://github.com/microsoft/playwright/issues/33566) fore details.
:::

```js
import { defineConfig, devices } from '@playwright/test';

export default defineConfig({
  projects: [
    /* Test against branded browsers. */
    {
      name: 'Google Chrome',
      use: { ...devices['Desktop Chrome'], channel: 'chrome' }, // or 'chrome-beta'
    },
    {
      name: 'Microsoft Edge',
      use: { ...devices['Desktop Edge'], channel: 'msedge' }, // or "msedge-beta" or 'msedge-dev'
    },
  ],
});
```

```java
import com.microsoft.playwright.*;

public class Example {
  public static void main(String[] args) {
    try (Playwright playwright = Playwright.create()) {
      // Channel can be "chrome", "msedge", "chrome-beta", "msedge-beta" or "msedge-dev".
      Browser browser = playwright.chromium().launch(new BrowserType.LaunchOptions().setChannel("msedge"));
      Page page = browser.newPage();
      // ...
    }
  }
}
```

```bash python
pytest test_login.py --browser-channel msedge
```

```xml csharp
<?xml version="1.0" encoding="utf-8"?>
<RunSettings>
  <Playwright>
    <BrowserName>chromium</BrowserName>
    <LaunchOptions>
      <Channel>msedge</Channel>
    </LaunchOptions>
  </Playwright>
</RunSettings>
```

```bash csharp
dotnet test -- Playwright.BrowserName=chromium Playwright.LaunchOptions.Channel=msedge
```

######
* langs: python

Alternatively when using the library directly, you can specify the browser [`option: BrowserType.launch.channel`] when launching the browser:

```python
from playwright.sync_api import sync_playwright

with sync_playwright() as p:
    # Channel can be "chrome", "msedge", "chrome-beta", "msedge-beta" or "msedge-dev".
    browser = p.chromium.launch(channel="msedge")
    page = browser.new_page()
    page.goto("http://playwright.dev")
    print(page.title())
    browser.close()
```

#### Installing Google Chrome & Microsoft Edge

If Google Chrome or Microsoft Edge is not available on your machine, you can install
them using the Playwright command line tool:

```bash lang=js
npx playwright install msedge
```

```bash lang=python
playwright install msedge
```

```bash lang=csharp
pwsh bin/Debug/netX/playwright.ps1 install msedge
```

```batch lang=java
mvn exec:java -e -D exec.mainClass=com.microsoft.playwright.CLI -D exec.args="install msedge"
```

:::warning
Google Chrome or Microsoft Edge installations will be installed at the
default global location of your operating system overriding your current browser installation.
:::

Run with the `--help` option to see a full a list of browsers that can be installed.

#### When to use Google Chrome & Microsoft Edge and when not to?

##### Defaults

Using the default Playwright configuration with the latest Chromium is a good idea most of the time.
Since Playwright is ahead of Stable channels for the browsers, it gives peace of mind that the
upcoming Google Chrome or Microsoft Edge releases won't break your site. You catch breakage
early and have a lot of time to fix it before the official Chrome update.

##### Regression testing

Having said that, testing policies often require regression testing to be performed against
the current publicly available browsers. In this case, you can opt into one of the stable channels,
`"chrome"` or `"msedge"`.

##### Media codecs

Another reason for testing using official binaries is to test functionality related to media codecs.
Chromium does not have all the codecs that Google Chrome or Microsoft Edge are bundling due to
various licensing considerations and agreements. If your site relies on this kind of codecs (which is
rarely the case), you will also want to use the official channel.

##### Enterprise policy

Google Chrome and Microsoft Edge respect enterprise policies, which include limitations to the capabilities, network proxy, mandatory extensions that stand in the way of testing. So if you are part of the organization that uses such policies, it is easiest to use bundled Chromium for your local testing, you can still opt into stable channels on the bots that are typically free of such restrictions.

### Firefox

Playwright's Firefox version matches the recent [Firefox Stable](https://www.mozilla.org/en-US/firefox/new/) build. Playwright doesn't work with the branded version of Firefox since it relies on patches.

Note that availability of certain features, which depend heavily on the underlying platform, may vary between operating systems. For example, available media codecs vary substantially between Linux, macOS and Windows.

### WebKit

Playwright's WebKit is derived from the latest WebKit main branch sources, often before these updates are incorporated into Apple Safari and other WebKit-based browsers. This gives a lot of lead time to react on the potential browser update issues. Playwright doesn't work with the branded version of Safari since it relies on patches. Instead, you can test using the most recent WebKit build.

Note that availability of certain features, which depend heavily on the underlying platform, may vary between operating systems. For example, available media codecs vary substantially between Linux, macOS and Windows. While running WebKit on Linux CI is usually the most affordable option, for the closest-to-Safari experience you should run WebKit on mac, for example if you do video playback.

## Install behind a firewall or a proxy

By default, Playwright downloads browsers from Microsoft's CDN.

Sometimes companies maintain an internal proxy that blocks direct access to the public
resources. In this case, Playwright can be configured to download browsers via a proxy server.

```bash tab=bash-bash lang=js
HTTPS_PROXY=https://192.0.2.1 npx playwright install
```

```batch tab=bash-batch lang=js
set HTTPS_PROXY=https://192.0.2.1
npx playwright install
```

```powershell tab=bash-powershell lang=js
$Env:HTTPS_PROXY="https://192.0.2.1"
npx playwright install
```

```bash tab=bash-bash lang=python
pip install playwright
HTTPS_PROXY=https://192.0.2.1 playwright install
```

```batch tab=bash-batch lang=python
set HTTPS_PROXY=https://192.0.2.1
pip install playwright
playwright install
```

```powershell tab=bash-powershell lang=python
$Env:HTTPS_PROXY="https://192.0.2.1"
pip install playwright
playwright install
```

```bash tab=bash-bash lang=java
HTTPS_PROXY=https://192.0.2.1 mvn exec:java -e -D exec.mainClass=com.microsoft.playwright.CLI -D exec.args="install"
```

```batch tab=bash-batch lang=java
set HTTPS_PROXY=https://192.0.2.1
mvn exec:java -e -D exec.mainClass=com.microsoft.playwright.CLI -D exec.args="install"
```

```powershell tab=bash-powershell lang=java
$Env:HTTPS_PROXY="https://192.0.2.1"
mvn exec:java -e -D exec.mainClass=com.microsoft.playwright.CLI -D exec.args="install"
```

```bash tab=bash-bash lang=csharp
HTTPS_PROXY=https://192.0.2.1 pwsh bin/Debug/netX/playwright.ps1 install
```

```batch tab=bash-batch lang=csharp
set HTTPS_PROXY=https://192.0.2.1
pwsh bin/Debug/netX/playwright.ps1 install
```

```powershell tab=bash-powershell lang=csharp
$Env:HTTPS_PROXY="https://192.0.2.1"
pwsh bin/Debug/netX/playwright.ps1 install
```

If the requests of the proxy get intercepted with a custom untrusted certificate authority (CA) and it yields to `Error: self signed certificate in certificate chain` while downloading the browsers, you must set your custom root certificates via the [`NODE_EXTRA_CA_CERTS`](https://nodejs.org/api/cli.html#node_extra_ca_certsfile) environment variable before installing the browsers:

```bash tab=bash-bash
export NODE_EXTRA_CA_CERTS="/path/to/cert.pem"
```

```batch tab=bash-batch
set NODE_EXTRA_CA_CERTS="C:\certs\root.crt"
```

```powershell tab=bash-powershell
$Env:NODE_EXTRA_CA_CERTS="C:\certs\root.crt"
```

If your network is slow to connect to Playwright browser archive, you can increase the connection timeout in milliseconds with `PLAYWRIGHT_DOWNLOAD_CONNECTION_TIMEOUT` environment variable:

```bash tab=bash-bash lang=js
PLAYWRIGHT_DOWNLOAD_CONNECTION_TIMEOUT=120000 npx playwright install
```

```batch tab=bash-batch lang=js
set PLAYWRIGHT_DOWNLOAD_CONNECTION_TIMEOUT=120000
npx playwright install
```

```powershell tab=bash-powershell lang=js
$Env:PLAYWRIGHT_DOWNLOAD_CONNECTION_TIMEOUT="120000"
npx playwright install
```

```bash tab=bash-bash lang=python
pip install playwright
PLAYWRIGHT_DOWNLOAD_CONNECTION_TIMEOUT=120000 playwright install
```

```batch tab=bash-batch lang=python
set PLAYWRIGHT_DOWNLOAD_CONNECTION_TIMEOUT=120000
pip install playwright
playwright install
```

```powershell tab=bash-powershell lang=python
$Env:PLAYWRIGHT_DOWNLOAD_CONNECTION_TIMEOUT="120000"
pip install playwright
playwright install
```

```bash tab=bash-bash lang=java
PLAYWRIGHT_DOWNLOAD_CONNECTION_TIMEOUT=120000 mvn exec:java -e -D exec.mainClass=com.microsoft.playwright.CLI -D exec.args="install"
```

```batch tab=bash-batch lang=java
set PLAYWRIGHT_DOWNLOAD_CONNECTION_TIMEOUT=120000
mvn exec:java -e -D exec.mainClass=com.microsoft.playwright.CLI -D exec.args="install"
```

```powershell tab=bash-powershell lang=java
$Env:PLAYWRIGHT_DOWNLOAD_CONNECTION_TIMEOUT="120000"
mvn exec:java -e -D exec.mainClass=com.microsoft.playwright.CLI -D exec.args="install"
```

```bash tab=bash-bash lang=csharp
PLAYWRIGHT_DOWNLOAD_CONNECTION_TIMEOUT=120000 pwsh bin/Debug/netX/playwright.ps1 install
```

```batch tab=bash-batch lang=csharp
set PLAYWRIGHT_DOWNLOAD_CONNECTION_TIMEOUT=120000
pwsh bin/Debug/netX/playwright.ps1 install
```

```powershell tab=bash-powershell lang=csharp
$Env:PLAYWRIGHT_DOWNLOAD_CONNECTION_TIMEOUT="120000"
pwsh bin/Debug/netX/playwright.ps1 install
```

If you are [installing dependencies](#install-system-dependencies) and need to use a proxy on Linux, make sure to run the command as a root user. Otherwise, Playwright will attempt to become a root and will not pass environment variables like `HTTPS_PROXY` to the linux package manager.

```bash js
sudo HTTPS_PROXY=https://192.0.2.1 npx playwright install-deps
```

```bash java
sudo HTTPS_PROXY=https://192.0.2.1 mvn exec:java -e -D exec.mainClass=com.microsoft.playwright.CLI -D exec.args="install-deps"
```

```bash python
sudo HTTPS_PROXY=https://192.0.2.1 playwright install-deps
```

```bash csharp
sudo HTTPS_PROXY=https://192.0.2.1 pwsh bin/Debug/netX/playwright.ps1 install-deps
```

## Download from artifact repository

By default, Playwright downloads browsers from Microsoft's CDN.

Sometimes companies maintain an internal artifact repository to host browser
binaries. In this case, Playwright can be configured to download from a custom
location using the `PLAYWRIGHT_DOWNLOAD_HOST` env variable.

```bash tab=bash-bash lang=js
PLAYWRIGHT_DOWNLOAD_HOST=http://192.0.2.1 npx playwright install
```

```batch tab=bash-batch lang=js
set PLAYWRIGHT_DOWNLOAD_HOST=http://192.0.2.1
npx playwright install
```

```powershell tab=bash-powershell lang=js
$Env:PLAYWRIGHT_DOWNLOAD_HOST="http://192.0.2.1"
npx playwright install
```

```bash tab=bash-bash lang=python
pip install playwright
PLAYWRIGHT_DOWNLOAD_HOST=http://192.0.2.1 playwright install
```

```batch tab=bash-batch lang=python
set PLAYWRIGHT_DOWNLOAD_HOST=http://192.0.2.1
pip install playwright
playwright install
```

```powershell tab=bash-powershell lang=python
$Env:PLAYWRIGHT_DOWNLOAD_HOST="http://192.0.2.1"
pip install playwright
playwright install
```

```bash tab=bash-bash lang=java
PLAYWRIGHT_DOWNLOAD_HOST=http://192.0.2.1 mvn exec:java -e -D exec.mainClass=com.microsoft.playwright.CLI -D exec.args="install"
```

```batch tab=bash-batch lang=java
set PLAYWRIGHT_DOWNLOAD_HOST=http://192.0.2.1
mvn exec:java -e -D exec.mainClass=com.microsoft.playwright.CLI -D exec.args="install"
```

```powershell tab=bash-powershell lang=java
$Env:PLAYWRIGHT_DOWNLOAD_HOST="http://192.0.2.1"
mvn exec:java -e -D exec.mainClass=com.microsoft.playwright.CLI -D exec.args="install"
```

```bash tab=bash-bash lang=csharp
PLAYWRIGHT_DOWNLOAD_HOST=http://192.0.2.1 pwsh bin/Debug/netX/playwright.ps1 install
```

```batch tab=bash-batch lang=csharp
set PLAYWRIGHT_DOWNLOAD_HOST=http://192.0.2.1
pwsh bin/Debug/netX/playwright.ps1 install
```

```powershell tab=bash-powershell lang=csharp
$Env:PLAYWRIGHT_DOWNLOAD_HOST="http://192.0.2.1"
pwsh bin/Debug/netX/playwright.ps1 install
```

It is also possible to use a per-browser download hosts using `PLAYWRIGHT_CHROMIUM_DOWNLOAD_HOST`, `PLAYWRIGHT_FIREFOX_DOWNLOAD_HOST` and `PLAYWRIGHT_WEBKIT_DOWNLOAD_HOST` env variables that
take precedence over `PLAYWRIGHT_DOWNLOAD_HOST`.

```bash tab=bash-bash lang=js
PLAYWRIGHT_FIREFOX_DOWNLOAD_HOST=http://203.0.113.3 PLAYWRIGHT_DOWNLOAD_HOST=http://192.0.2.1 npx playwright install
```

```batch tab=bash-batch lang=js
set PLAYWRIGHT_FIREFOX_DOWNLOAD_HOST=http://203.0.113.3
set PLAYWRIGHT_DOWNLOAD_HOST=http://192.0.2.1
npx playwright install
```

## Managing browser binaries

Playwright downloads Chromium, WebKit and Firefox browsers into the OS-specific cache folders:

- `%USERPROFILE%\AppData\Local\ms-playwright` on Windows
- `~/Library/Caches/ms-playwright` on macOS
- `~/.cache/ms-playwright` on Linux

These browsers will take a few hundred megabytes of disk space when installed:

```bash
du -hs ~/Library/Caches/ms-playwright/*
281M  chromium-XXXXXX
187M  firefox-XXXX
180M  webkit-XXXX
```

You can override default behavior using environment variables. When installing Playwright, ask it to download browsers into a specific location:

```bash tab=bash-bash lang=js
PLAYWRIGHT_BROWSERS_PATH=$HOME/pw-browsers npx playwright install
```

```batch tab=bash-batch lang=js
set PLAYWRIGHT_BROWSERS_PATH=%USERPROFILE%\pw-browsers
npx playwright install
```

```powershell tab=bash-powershell lang=js
$Env:PLAYWRIGHT_BROWSERS_PATH="$Env:USERPROFILE\pw-browsers"
npx playwright install
```

```bash tab=bash-bash lang=python
pip install playwright
PLAYWRIGHT_BROWSERS_PATH=$HOME/pw-browsers python -m playwright install
```

```batch tab=bash-batch lang=python
set PLAYWRIGHT_BROWSERS_PATH=%USERPROFILE%\pw-browsers
pip install playwright
playwright install
```

```powershell tab=bash-powershell lang=python
$Env:PLAYWRIGHT_BROWSERS_PATH="$Env:USERPROFILE\pw-browsers"
pip install playwright
playwright install
```

```bash tab=bash-bash lang=java
PLAYWRIGHT_BROWSERS_PATH=$HOME/pw-browsers mvn exec:java -e -D exec.mainClass=com.microsoft.playwright.CLI -D exec.args="install"
```

```batch tab=bash-batch lang=java
set PLAYWRIGHT_BROWSERS_PATH=%USERPROFILE%\pw-browsers
mvn exec:java -e -D exec.mainClass=com.microsoft.playwright.CLI -D exec.args="install"
```

```powershell tab=bash-powershell lang=java
$Env:PLAYWRIGHT_BROWSERS_PATH="$Env:USERPROFILE\pw-browsers"
mvn exec:java -e -D exec.mainClass=com.microsoft.playwright.CLI -D exec.args="install"
```

```bash tab=bash-bash lang=csharp
PLAYWRIGHT_BROWSERS_PATH=$HOME/pw-browsers pwsh bin/Debug/netX/playwright.ps1 install
```

```batch tab=bash-batch lang=csharp
set PLAYWRIGHT_BROWSERS_PATH=%USERPROFILE%\pw-browsers
pwsh bin/Debug/netX/playwright.ps1 install
```

```powershell tab=bash-powershell lang=csharp
$Env:PLAYWRIGHT_BROWSERS_PATH="$Env:USERPROFILE\pw-browsers"
pwsh bin/Debug/netX/playwright.ps1 install
```

When running Playwright scripts, ask it to search for browsers in a shared location.

```bash tab=bash-bash lang=js
PLAYWRIGHT_BROWSERS_PATH=$HOME/pw-browsers npx playwright test
```

```batch tab=bash-batch lang=js
set PLAYWRIGHT_BROWSERS_PATH=%USERPROFILE%\pw-browsers
npx playwright test
```

```powershell tab=bash-powershell lang=js
$Env:PLAYWRIGHT_BROWSERS_PATH="$Env:USERPROFILE\pw-browsers"
npx playwright test
```

```bash tab=bash-bash lang=python
PLAYWRIGHT_BROWSERS_PATH=$HOME/pw-browsers python playwright_script.py
```

```batch tab=bash-batch lang=python
set PLAYWRIGHT_BROWSERS_PATH=%USERPROFILE%\pw-browsers
python playwright_script.py
```

```powershell tab=bash-powershell lang=python

$Env:PLAYWRIGHT_BROWSERS_PATH="$Env:USERPROFILE\pw-browsers"
python playwright_script.py
```

```bash tab=bash-bash lang=java
PLAYWRIGHT_BROWSERS_PATH=$HOME/pw-browsers mvn test
```

```batch tab=bash-batch lang=java
set PLAYWRIGHT_BROWSERS_PATH=%USERPROFILE%\pw-browsers
mvn test
```

```powershell tab=bash-powershell lang=java
$Env:PLAYWRIGHT_BROWSERS_PATH="$Env:USERPROFILE\pw-browsers"
mvn test
```

```bash tab=bash-bash lang=csharp
PLAYWRIGHT_BROWSERS_PATH=$HOME/pw-browsers dotnet test
```

```batch tab=bash-batch lang=csharp
set PLAYWRIGHT_BROWSERS_PATH=%USERPROFILE%\pw-browsers
dotnet test
```

```powershell tab=bash-powershell lang=csharp
$Env:PLAYWRIGHT_BROWSERS_PATH="$Env:USERPROFILE\pw-browsers"
dotnet test
```

Playwright keeps track of packages that need those browsers and will garbage collect them as you update Playwright to the newer versions.

:::note
Developers can opt-in in this mode via exporting `PLAYWRIGHT_BROWSERS_PATH=$HOME/pw-browsers` in their `.bashrc`.
:::

### Hermetic install
* langs: js

You can opt into the hermetic install and place binaries in the local folder:


```bash tab=bash-bash
# Places binaries to node_modules/playwright-core/.local-browsers
PLAYWRIGHT_BROWSERS_PATH=0 npx playwright install
```

```batch tab=bash-batch
# Places binaries to node_modules\playwright-core\.local-browsers
set PLAYWRIGHT_BROWSERS_PATH=0
npx playwright install
```

```powershell tab=bash-powershell
# Places binaries to node_modules\playwright-core\.local-browsers
$Env:PLAYWRIGHT_BROWSERS_PATH=0
npx playwright install
```

:::note
`PLAYWRIGHT_BROWSERS_PATH` does not change installation path for Google Chrome and Microsoft Edge.
:::

### Skip browser downloads
* langs: java

In certain cases, it is desired to avoid browser downloads altogether because
browser binaries are managed separately.

This can be done by setting `PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD` variable before installation.

```bash tab=bash-bash lang=java
PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD=1 mvn test
```

```batch tab=bash-batch lang=java
set PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD=1
mvn test
```

```powershell tab=bash-powershell lang=java
$Env:PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD=1
mvn test
```

### Stale browser removal

Playwright keeps track of the clients that use its browsers. When there are no more clients that require a particular version of the browser, that version is deleted from the system. That way you can safely use Playwright instances of different versions and at the same time, you don't waste disk space for the browsers that are no longer in use.

To opt-out from the unused browser removal, you can set the `PLAYWRIGHT_SKIP_BROWSER_GC=1` environment variable.

### Uninstall browsers

This will remove the browsers (chromium, firefox, webkit) of the current Playwright installation:

```bash js
npx playwright uninstall
```

```bash java
mvn exec:java -e -D exec.mainClass=com.microsoft.playwright.CLI -D exec.args="uninstall"
```

```bash python
playwright uninstall
```

```bash csharp
pwsh bin/Debug/netX/playwright.ps1 uninstall
```

To remove browsers of other Playwright installations as well, pass `--all` flag:

```bash js
npx playwright uninstall --all
```

```bash java
mvn exec:java -e -D exec.mainClass=com.microsoft.playwright.CLI -D exec.args="uninstall --all"
```

```bash python
playwright uninstall --all
```

```bash csharp
pwsh bin/Debug/netX/playwright.ps1 uninstall --all
```
