Documented steps Install Playwright core (no local browser download needed since the browser runs in the cloud): `npm install playwright-core`. Create a Browserbase session to get a session id and connectUrl (see create-session route). Connect with Chromium over CDP: `const browser = await chromium.connectOverCDP(session.connectUrl); const page = browser.contexts()[0].pages()[0];` Interact normally: `await page.goto(url)`, `page.locator(...).click()`, `page.locator(...).fill(...)`, `await page.content()`. Close cleanly when done: `await browser.close()` so the session can shut down and stop billing. Official doc: https://docs.browserbase.com/platform/browser/getting-started/using-browser-session Known gotchas Use `playwright-core` (framework) rather than `playwright` (which bundles a local browser) when connecting to Browserbase over CDP. Grab the page from `browser.contexts()[0].pages()[0]` — there is already a default context and page after connectOverCDP. Always call browser.close() / end the session to avoid lingering billable browser time.
