# `cdp`

Also expose a Chrome DevTools Protocol endpoint (cdpUrl).

**Use it for:** Puppeteer users and tools that speak raw CDP (Lighthouse, custom DevTools clients), or connecting with Playwright's connectOverCDP to reach Chromium-only features like network throttling and performance traces.

**Browsers:** [Google Chrome](https://cdpfleet.com/docs/browsers/chrome#opt-cdp), [Microsoft Edge](https://cdpfleet.com/docs/browsers/edge#opt-cdp), [Brave](https://cdpfleet.com/docs/browsers/brave#opt-cdp), [Opera](https://cdpfleet.com/docs/browsers/opera#opt-cdp), [Yandex Browser](https://cdpfleet.com/docs/browsers/yandex#opt-cdp), [Chromium](https://cdpfleet.com/docs/browsers/chromium#opt-cdp).

## Details

-   **Type:** `boolean`
-   **Default:** false
-   **Example:** `{"cdp":true}`

The launch response then carries `cdpUrl` next to `wsUrl`: a browser-level CDP WebSocket for Puppeteer (`puppeteer.connect({ browserWSEndpoint: cdpUrl, headers })`), Playwright's `connectOverCDP(cdpUrl, { headers })` in any language and version, or any raw CDP client (key in the `x-api-key` header or `?api_key=`).

Same session, proxy and limits. You can connect to `wsUrl` and `cdpUrl` at once, but closing either ends the session. Not on Patchright and Rebrowser (their stealth lives in the Playwright layer CDP bypasses), Whale, Camoufox, Firefox or WebKit.
