Protected Web Access, sessions, browser actions, all handled. ## Operate dynamic websites with browser sessions. Give your agents and workflows a real browser when pages require clicks, forms, login, pagination, session state, or multi-step navigation. Puppeteer, Playwright, any CDP client. Protected Web Access included. Formerly [Scraping Browser](https://docs.zenrows.com/browser-sessions/introduction) , now Browser. What you'd manage without Browser - Browser pool Spin up, cap, and tear down concurrent Chromium processes - Reconnect logic Detect CDP drops, retry connections, resume mid-flow - Memory ceiling Kill idle tabs, evict stalled sessions, prevent OOM crashes - Session storage Persist and rehydrate cookies and auth tokens across restarts - Proxy routing Thread each session through clean residential IPs per domain - Health checks Detect hung navigations, stalled pages, and silent failures at scale ## Your code is the driver. Drive it from the CLI with no key, or connect your own Playwright. Click. Type. Wait. Read the DOM back. ``` $ npm i -g @zenrows/cli $ zenrows browser open \ https://www.scrapingcourse.com/ecommerce/ ✓ Session 7cca8947… $ zenrows browser click \ --session 7cca8947… \ --selector a.next $ zenrows browser get-text \ --session 7cca8947… \ --selector \ .woocommerce-result-count Showing 17–32 of 188 results $ zenrows browser close \ --session 7cca8947… ✓ Closed session 7cca8947…. ``` ``` import { chromium } from "playwright"; const browser = await chromium.connectOverCDP( "wss://browser.zenrows.com?apikey=ZR_•••" ); const page = await browser.newPage(); await page.goto("https://example.com/login"); await page.fill("#email", "you@team.com"); await page.fill("#password", secret); await page.click("button[type=submit]"); await page.waitForURL("**/dashboard"); return await page.content(); ``` ``` import puppeteer from "puppeteer"; const browser = await puppeteer.connect({ browserWSEndpoint: "wss://browser.zenrows.com?apikey=ZR_•••", }); const page = await browser.newPage(); await page.goto("https://example.com/login"); await page.type("#email", "you@team.com"); await page.type("#password", secret); await page.click("button[type=submit]"); await page.waitForNavigation(); return await page.content(); ``` No drivers. No headless quirks. The Chromium runs on Zenrows. Your code runs anywhere. Sessions persist, the Protected Network routes, Protected Web Access stays out of the way. A session closes after 15 minutes. It bills 5 credits a minute, plus 25,000 credits a GB. ## Build any flow from browser actions. Navigate, fill, click, wait, screenshot, evaluate. Compose them in any order to handle any page. - 01 goto Navigate to any URL. Anti-bot, proxies, sessions, routed transparently. - 02 fill Type into any input. Forms, search boxes, auth credentials. - 03 click Click any selector. Buttons, links, dropdowns, modals. - 04 waitFor Wait for selector, URL change, or network idle. No race conditions. - 05 screenshot Capture the page. Viewport, full-page, or a specific element. - 06 evaluate Run JavaScript in the page context. Read the DOM, post events. ## Sessions persist. Cookies, auth, open tabs, they stay alive across calls. Build flows that span pages without reconnecting. - POST /auth Submit credentials The browser fills the form and posts to the auth endpoint. page.fill( "#email" , email); page.fill( "#password" , secret); page.click( "button[type=submit]" ); - SET-COOKIE The session lives. Auth response carries a cookie. The browser holds it. Every subsequent call rides it. Set-Cookie : session=abc123…; HttpOnly - GET /dashboard Stay authenticated. Navigate anywhere on the site. The session cookie rides along, no re-auth. page.goto( "/dashboard" ); // 200 OK — no redirect to /login - GET /api/report Pull the data. Hit the authenticated endpoint. Read the response. Done. const data = await page.evaluate( () => fetch( "/api/report" ).then(r => r.json()) ); ## Already in your stack. Any framework that speaks CDP speaks to Zenrows. No SDK lock-in. No driver install. ``` from playwright.sync_api import sync_playwright with sync_playwright() as p: browser = p.chromium.connect_over_cdp( "wss://browser.zenrows.com?apikey=…" ) ``` ``` import { chromium } from "playwright"; const browser = await chromium.connectOverCDP( "wss://browser.zenrows.com?apikey=…" ); ``` ``` import puppeteer from "puppeteer"; const browser = await puppeteer.connect({ browserWSEndpoint: "wss://browser.zenrows.com/…", }); ``` ``` const ws = new WebSocket( "wss://browser.zenrows.com/…" ); ws.send(JSON.stringify({ id: 1, method: "Page.navigate", … })); ``` ## Connect the browser. Free plan. 5,000 credits every month. No driver install.
