Playwright Python Automation

🔑 WebAuthn passkeys

New Credentials virtual authenticator, available via browserContext.credentials, lets tests register passkeys and answer navigator.credentials.create() / navigator.credentials.get() ceremonies in the page — no real hardware key required, works in all browsers:

context = browser.new_context()

# Seed a passkey your backend provisioned for a test user.
context.credentials.create("example.com",
    id=credential_id,
    user_handle=user_handle,
    private_key=private_key,
    public_key=public_key,
)
context.credentials.install()

page = context.new_page()
page.goto("https://example.com/login")
# The page's navigator.credentials.get() is answered with the seeded passkey.

You can also let the app register a passkey once in a setup test, read it back with credentials.get(), and seed it into later tests — see Credentials for details.

🗃️ Web Storage

New WebStorage API, available via page.localStorage and page.sessionStorage, reads and writes the page's storage for the current origin:

page.local_storage.set_item("token", "abc")
token = page.local_storage.get_item("token")
items = page.session_storage.items()

New APIs

• apiResponse.security_details() and apiResponse.server_addr() mirror the browser-side response.security_details() and response.server_addr().
• New option artifacts_dir in browserType.connect_over_cdp() controls where artifacts such as traces and downloads are stored when attached to an existing browser.
• New option cursor in screencast.show_actions() controls the cursor decoration rendered for pointer actions.
• The on_frame callback in screencast.start() now receives a timestamp of when the frame was presented by the browser.

🛠️ Other improvements

• Playwright now supports Ubuntu 26.04.
• HAR and trace recordings now include WebSocket requests.

Example

from playwright.sync_api import sync_playwright

with sync_playwright() as p:
    for browser_type in [p.chromium, p.firefox, p.webkit]:
        browser = browser_type.launch()
        page = browser.new_page()
        page.goto('http://playwright.dev')
        page.screenshot(path=f'example-{browser_type.name}.png')
        browser.close()

import asyncio
from playwright.async_api import async_playwright

async def main():
    async with async_playwright() as p:
        for browser_type in [p.chromium, p.firefox, p.webkit]:
