Documented steps pip install playwright steel-sdk Create a session: session = client.sessions.create() Connect (sync API): browser = playwright.chromium.connect_over_cdp(f"{session.websocket_url}&apiKey={STEEL_API_KEY}") Reuse the session's existing browser context (browser.contexts[0]) rather than creating a new context, so activity is captured in the session viewer Drive the page with standard Playwright calls, then clean up with client.sessions.release(session.id) Docs: https://docs.steel.dev/overview/guides/playwright-python Known gotchas apiKey rides in the websocket URL query string (f"{session.websocket_url}&apiKey={key}"), not in a header Do not create a new browser context — use the one the session already opened, or the live viewer/recording misses your pages Default 5-minute session timeout applies unless you pass timeout= at creation; hard cap cannot be changed mid-session
