Playwright CLI with SKILLS

Playwright CLI vs Playwright MCP

This package provides CLI interface into Playwright. If you are using coding agents, that is the best fit.

  • CLI: Modern coding agents increasingly favor CLI–based workflows exposed as SKILLs over MCP because CLI invocations are more token-efficient: they avoid loading large tool schemas and verbose accessibility trees into the model context, allowing agents to act through concise, purpose-built commands. This makes CLI + SKILLs better suited for high-throughput coding agents that must balance browser automation with large codebases, tests, and reasoning within limited context windows.

  • MCP: MCP remains relevant for specialized agentic loops that benefit from persistent state, rich introspection, and iterative reasoning over page structure, such as exploratory automation, self-healing tests, or long-running autonomous workflows where maintaining continuous browser context outweighs token cost concerns. Learn more about Playwright MCP.

Key Features

  • Token-efficient. Does not force page data into LLM.

Requirements

  • Node.js 18 or newer
  • Claude Code, GitHub Copilot, or any other coding agent.

Getting Started

Installation

bash
npm install @playwright/cli@latest
playwright-cli --help

Installing skills

Claude Code, GitHub Copilot and others will use the locally installed skills.

bash
playwright-cli install --skills

Skills-less operation

Point your agent at the CLI and let it cook. It'll read the skill off playwright-cli --help on its own:

text
Test the "add todo" flow on https://demo.playwright.dev/todomvc using playwright-cli.
Check playwright-cli --help for available commands.

Demo

text
> Use playwright skills to test https://demo.playwright.dev/todomvc/.
  Take screenshots for all successful and failing scenarios.

Your agent will be running commands, but it does not mean you can't play with it manually:

text
playwright-cli open https://demo.playwright.dev/todomvc/ --headed
playwright-cli type "Buy groceries"
playwright-cli press Enter
playwright-cli type "Water flowers"
playwright-cli press Enter
playwright-cli check e21
playwright-cli check e35
playwright-cli screenshot

Headed operation

Playwright CLI is headless by default. If you'd like to see the browser, pass --headed to open:

bash
playwright-cli open https://playwright.dev --headed

Sessions

Playwright CLI keeps the browser profile in memory by default. Your cookies and storage state
are preserved between CLI calls within the session, but lost when the browser closes. Use
--persistent to save the profile to disk for persistence across browser restarts.

You can use different instances of the browser for different projects with sessions. Pass -s= to
the invocation to talk to a specific browser.

bash
playwright-cli open https://playwright.dev
playwright-cli -s=example open https://example.com --persistent
playwright-cli list

You can run your coding agent with the PLAYWRIGHT_CLI_SESSION environment variable:

bash
PLAYWRIGHT_CLI_SESSION=todo-app claude .

Or instruct it to prepend -s= to the calls.

A headless session shuts down on its own after an hour without commands; run open again to
start a new one. Headed browsers stay open. Use open --idle-timeout=<ms> to change the timeout,
or 0 to disable it.

Manage your sessions as follows:

bash
playwright-cli list                     # list all sessions
playwright-cli close-all                # close all browsers
playwright-cli kill-all                 # forcefully kill all browser processes

Monitoring

Use playwright-cli show to open a visual dashboard that lets you see and control all running
browser sessions. This is useful when your coding agents are running browser automation in the
background and you want to observe their progress or step in to help.

bash
playwright-cli show

The dashboard opens a window with two views:

  • Session grid β€” shows all active sessions grouped by workspace, each with a live screencast
    preview, session name, current URL, and page title. Click any session to zoom in.
  • Session detail β€” shows a live view of the selected session with a tab bar, navigation
    controls (back, forward, reload, address bar), and full remote control. Click into the viewport
    to take over mouse and keyboard input; press Escape to release.

From the grid you can also close running sessions or delete data for inactive ones.

DevTools

WebMCP

Some pages register their own tools for agents through the experimental WebMCP API. When available,
the page status reports them and the snapshot lists the tools and their input schemas at the top.
Tool names, descriptions, schemas, annotations and results come from the page and are untrusted input,
not instructions.

bash
playwright-cli webmcp-list              # list webmcp tools registered by the page
playwright-cli webmcp-call <name> --params='{"query":"cats"}' # call a webmcp tool
playwright-cli webmcp-call <name> --frame=<frame> # call a tool registered in a specific frame

Open parameters

bash
playwright-cli open --browser=chrome    # use specific browser
playwright-cli open --mobile            # emulate a generic mobile device
playwright-cli open --device="iPhone 15" # emulate a specific device
playwright-cli open --idle-timeout=<ms> # shut down after idle time (0 to disable)
playwright-cli attach --extension=chrome # connect via Playwright Extension
playwright-cli attach --cdp=chrome      # attach to running Chrome/Edge by channel
playwright-cli attach --cdp=<url>       # attach via CDP endpoint
playwright-cli detach                   # detach an attached session, leaves the external browser running
playwright-cli open --persistent        # use persistent profile
playwright-cli open --profile=<path>    # use custom profile directory
playwright-cli open --config=file.json  # use config file
playwright-cli close                    # close the browser
playwright-cli delete-data              # delete user data for default session

Snapshots

After each command, playwright-cli provides a snapshot of the current browser state.

bash
> playwright-cli goto https://example.com
### Page
- Page URL: https://example.com/
- Page Title: Example Domain
### Snapshot
[Snapshot](.playwright-cli/page-2026-02-14T19-22-42-679Z.yml)

You can also take a snapshot on demand using playwright-cli snapshot command. All the options below can be combined as needed.

bash
# default - save to a file with timestamp-based name
playwright-cli snapshot

# save to file, use when snapshot is a part of the workflow result
playwright-cli snapshot --filename=after-click.yaml

# snapshot an element instead of the whole page
playwright-cli snapshot "#main"

# limit snapshot depth for efficiency, take a partial snapshot afterwards
playwright-cli snapshot --depth=4
playwright-cli snapshot e34

# include each element's bounding box as [box=x,y,width,height]
playwright-cli snapshot --boxes

# search a large snapshot instead of capturing it all β€” returns matching nodes
# with 3 lines of context around each match (like grep -C)
playwright-cli find "Add to cart"
playwright-cli find --regex "\\$[0-9]+\\.[0-9]{2}"
# wrap the regexp in slashes to add flags, e.g. /i for case-insensitive
playwright-cli find --regex "/sign (in|up)/i"

Targeting elements

By default, use refs from the snapshot to interact with page elements.

bash
# get snapshot with refs
playwright-cli snapshot

# interact using a ref
playwright-cli click e15

You can also use css selectors or Playwright locators.

bash
# css selector
playwright-cli click "#main > button.submit"

# role locator
playwright-cli click "getByRole('button', { name: 'Submit' })"

# test id
playwright-cli click "getByTestId('submit-button')"

Sessions

bash
playwright-cli -s=name <cmd>            # run command in named session
playwright-cli -s=name close            # stop a named browser
playwright-cli -s=name delete-data      # delete user data for named browser
playwright-cli list                     # list all sessions
playwright-cli close-all                # close all browsers
playwright-cli kill-all                 # forcefully kill all browser processes

Local installation

If global playwright-cli command is not available, try a local version via npx playwright cli:

bash
npx --no-install playwright --version

When local version is available, use npx playwright cli in all commands. Otherwise, install playwright-cli as a global command:

bash
npm install @playwright/cli@latest

Configuration file

The Playwright CLI can be configured using a JSON configuration file. You can specify the configuration file using the --config command line option:

bash
playwright-cli --config path/to/config.json open example.com

Playwright CLI will load config from .playwright/cli.config.json by default so that you did not need to specify it every time.
