# cdpfleet

> Real cloud browsers — Chrome, Edge, Brave, Opera, Whale, Yandex, Chromium, Patchright, Rebrowser, Camoufox, Firefox and WebKit — launched over HTTP and driven with Playwright, Puppeteer or CDP, with proxies, residential IPs, live view, recordings and persistent profiles.

AI agents: start with the skill page; it has the launch flow, the browser table, limits and errors in one place.

## Try it in one minute

**Why cdpfleet:** 12 real browsers (Chrome, Edge, Brave, Opera, Whale, Yandex, Chromium, Patchright,
Rebrowser, Camoufox, Firefox, WebKit) in the cloud, with beta/dev channels and older versions;
your own proxies, pools and per-host rules, or residential IPs by country from $0.50/GB; live view,
video recordings and persistent profiles; and dated measurements of what gets through Cloudflare,
DataDome, Akamai and HUMAN with each browser (https://cdpfleet.com/bot-protection).

**1. Get an API key** at https://cdpfleet.com/app (sign up free; every plan includes a free shared proxy, used when you
leave `proxy` out, so no proxy of your own is needed to start; what a paid plan adds: https://cdpfleet.com/upgrade).

**2a. From an AI assistant (MCP):** add the hosted server and sign in with OAuth:

```bash
claude mcp add --transport http cdpfleet https://cdpfleet.com/mcp
```

Or in any MCP client's config: `{ "mcpServers": { "cdpfleet": { "url": "https://cdpfleet.com/mcp" } } }`.
Local alternative: `npx -y cdpfleet-mcp` with `CDPFLEET_API_KEY` set. Tools: launch_browser, navigate,
snapshot, click, type, press, wait_for, screenshot, evaluate, live_view, close_browser, downloads,
list_browsers, account. Example prompts and the tool calls they make: https://cdpfleet.com/docs/mcp/prompts

**2b. From code (Playwright, any language):**

```js
const res = await fetch('https://starter.cdpfleet.com/chrome/session', {
  method: 'POST', headers: { 'x-api-key': process.env.CDPFLEET_API_KEY, 'content-type': 'application/json' },
  body: JSON.stringify({ headless: 'new' }),
});
const { wsUrl } = await res.json();
const browser = await chromium.connect(wsUrl, { headers: { 'x-api-key': process.env.CDPFLEET_API_KEY } });
```

Or with the SDK (npm/PyPI `cdpfleet`, Go module; it retries when the fleet is busy):
`const session = await new Cdpfleet().launch('chrome', { headless: 'new' }); const browser = await session.connect(chromium);`
— all five languages, runnable as they are: https://cdpfleet.com/docs/quickstart

**2c. No browser to drive (Functions):** one HTTP call returns a page as Markdown, a screenshot, extracted
fields or the same page from several countries:

```bash
curl -s https://cdpfleet.com/v1/functions/markdown -H "x-api-key: $CDPFLEET_API_KEY" \
  -H "content-type: application/json" -d '{"url":"https://books.toscrape.com/"}'
```

Also `screenshot`, `pdf`, `scrape` (with `extract`), `map`, `geo` and `livetab`; on paid plans, batch and crawl
jobs over any number of URLs and monitors that send a diff when a page changes: https://cdpfleet.com/docs/functions

Every page of this site is also available as Markdown: add `.md` to its URL, or send
`Accept: text/markdown`. Everything at once: https://cdpfleet.com/llms-full.txt

- [Bot protection](https://cdpfleet.com/bot-protection): Which browser got the real page behind Cloudflare, DataDome, Akamai, HUMAN, Kasada and AWS WAF, on real sites and on the vendors' own pages: 12 browsers, dated measurements in five languages, what didn't help, and when to stop.
- [Proxies](https://cdpfleet.com/proxies): Every cdpfleet session browses through a proxy: bring HTTP, HTTPS or SOCKS5 proxies, pools and per-host rules, swap the exit live, use the residential proxy by tier and country, or your own VPN. Measured in cases.
- [CDP & Puppeteer](https://cdpfleet.com/cdp): Drive cdpfleet browsers with Puppeteer, Playwright connectOverCDP or any Chrome DevTools Protocol client: add "cdp": true and connect to cdpUrl.

- [Pages to text for LLMs](https://cdpfleet.com/llm-data): Turn web pages into compact text for LLMs and RAG with a real remote browser: ARIA snapshots that keep links at about a third of the HTML, innerText for summaries, structured extraction in the page, and the hosted MCP server for assistants.
- [Scoreboard](https://cdpfleet.com/bot-protection/scoreboard): One table: how often each of 12 browsers (and a returning Camoufox profile) got the real page behind Cloudflare, DataDome, Akamai, HUMAN, Kasada and AWS WAF on real sites, from dated lab runs in five languages.
- [Security](https://cdpfleet.com/security): How cdpfleet keeps sessions apart and data private: sessions reach only the public internet, file: URLs are refused, keys travel in headers, recordings and downloads sit behind short-lived private links, VPN configs are stored encrypted.
- [Functions](https://cdpfleet.com/functions): cdpfleet Functions: screenshots, PDFs, Markdown, scraping with actions and extraction, site maps, geo compare, a live remote tab, batch and crawl jobs, live page watching, warmed-up browsers and change monitors — one HTTP call each, in real browsers.
